Does bio diesel produce green house gases?

Technically, yes it does.  But the neat thing about B100 is it is considered to be carbon neutral.\n\nWhat this means is that the amount of carbon released into the atmosphere is less than or equal to the carbon absorbed fromt he atmosphere by the plants.\n\nSo, while biodiesel does produce greenhouse gases.  Roughly the same amount of greenhouse gases were removed from the atmosphere by plant life to make the fuel.  And yes, if you use animal oils instead, you need to remember to follow the food chain back down to whatever ate the plant matter for the energy.\n\nKeep in mind, that certain aspects in the processing, transportation that require energy inputs that are not derived from renewable resources can potentially produce greenhouse gases as well.  Let's say that the farmer used a tractor powered by petroleum diesel.  In that case, you are slightly carbon positive since he didn't use the biodiesel to harvest the crop.

Depending on how much ethanol spilled. Ethanol is the same alcohol that is in wine, beer and liquor. Spilling\na significant amount in water will make the occupants drunk.\nSpilling a really significant could make them dead.\n\nAs far as ethanol giving off less CO2 than burning gasoline - it may give less. However, there is a tremendous quantity of CO2 given off in the fermentation process. I am curious whether there is any real green-house gas advantage.

Well of course if you spill them, it's kind of nasty. Think of engine oil scattered in your garage. It doesn't smell good - can cause respiratory problems. It can contaminate your drinking water. It can kill fish and other marine organisms.\n\nIf you burn them, like you use them to generate electricity. They will produce carbon dioxide which can contribute to global warming. This carbon dioxide gas functions like a glass .. (Have you ever seen a greenhouse?) wherein heat is trapped and cannot get out. This is what we call " greenhouse effect". And since heat is trapped, earth becomes warmer. This could lead to melting of icebergs and polar caps and some islands to submerge.\n\nLooking for a tutor?

fr_chuck, get your ass out of questions like this. You are a fucking evangelist and a preacher for cryin' out loud. I don't have to add that you are a neocon. You can't spell for wit (it's university, moron), so don't even attempt to answer questions about things you probably don't even know about it.\n\nTo the original poster, all I can say is that dioxin is used for molecular and cellular biology experiments. If used in laboratory processes, dioxin would be purchased from companies that supply to universities by stock. These chemicals are put into toxin bins and then disposed of properly.

Diesel or Diesel fuel is a specific fractional distillate of fuel oil (mostly petroleum) that is used as fuel in a diesel engine invented by German engineer Rudolf Diesel. The term typically refers to fuel that has been processed from petroleum, but increasingly, alternatives such as biodiesel or biomass to liquid (BTL) or gas to liquid (GTL) diesel that are not derived from petroleum are being developed.\nDiesel is produced from petroleum, and is sometimes called petrodiesel (or, less seriously, dinodiesel) when there is a need to distinguish it from diesel obtained from other sources. As a hydrocarbon mixture, it is obtained in the fractional distillation of crude oil between 250 °C and 350 °C at atmospheric pressure. Petro Diesel is considered to be a fuel oil and is about 18% denser than gasoline.\n\nThe density of diesel is about 850 grams per liter whereas gasoline has a density of about 720 g/l, or about 15% less. When burnt diesel typically releases about 40.9 megajoules (MJ) per liter, whereas gasoline releases 34.8 MJ/l also about 15% less. Diesel is generally simpler to refine than gasoline and often costs less (although price fluctuations often mean that the inverse is true; for example, the cost of diesel traditionally rises during colder months as demand for heating oil, which is refined much the same way, rises).\n\nDiesel fuel, however, often contains higher quantities of sulfur. In Europe, emission standards and preferential taxation have both forced oil refineries to dramatically reduce the level of sulfur in diesel fuels. In contrast, the United States has long had "dirtier" diesel, although more stringent emission standards have been adopted with the transition to ultra-low sulfur diesel (ULSD) occurring in 2006 (see also diesel exhaust). U.S. diesel fuel typically also has a lower cetane number (a measure of ignition quality) than European diesel, resulting in worse cold weather performance and some increase in emissions. High levels of sulfur in diesel are harmful for the environment. It prevents the use of catalytic diesel particulate filters to control diesel particulate emissions, as well as more advanced technologies, such as nitrogen oxide (NOx) adsorbers (still under development), to reduce emissions. However, lowering sulfur also reduces the lubricity of the fuel, meaning that additives must be put into the fuel to help lubricate engines. Biodiesel is an effective lubricant. Diesel contains approximately 18% more energy per unit of volume than gasoline, which, along with the greater efficiency of diesel engines, contributes to fuel economy (distance traveled per volume of fuel consumed).\n\nThere has been a lot of discussion and misinformation about algae in diesel fuel. Algae is a plant, and it requires sunlight to live and grow. As there is no sunlight in a closed fuel tank, no algae can survive there. However, some microbes can survive there. They can feed on the diesel fuel.\n\nThese microbes form a slimy colony that lives at the fuel/water interface. They grow quite rapidly in warmer temperatures. They can even grow in cold weather when fuel tank heaters are installed. Parts of the colony can break off and clog the fuel lines and fuel filters.\n\nIt is possible to either kill this growth with a biocide treatment, or eliminate the water, a necessary component of microbial life. There are a number of biocides on the market, which must be handled very carefully. If a biocide is used, it must be added every time a tank is refilled until the problem is fully resolved.\n\nBiocides attack the cell wall of microbes resulting in Lysis, the death of a cell by bursting. The risk of filter clogging may continue for a short period after biocide treatment until cellular residues break down and are absorbed into the fuel.\n\nDiesel fuel is very similar to heating oil which is used in central heating. In Europe, the United States and Canada, taxes on diesel fuel are higher than on heating oil due

Diesel engines were built to run on vegetable oil also. But it only works when the engine is at a certain temperater so you have to have to fuel tanks on for diesel and one for veggie oil when the engine reaches the right temp you switch to veggie power. You can buy kits to modify your car this way and there are a few garages that will do it for you.

Your question is not very specific. However, here are some information that might be helpful.\n\n1. If you are pertaining to fresh concrete, there is no specific record on the degrading effect of diesel. In fact, actual construction sometimes uses diesel based form release agents that debonds the fresh concrete from the formwork. Diesel is oil based. Knowing that, it will not in anyway mix or affect water content of the fresh concrete since oil and water repel each other. It may be important to note however, that there is no defined ACI or ASTM specification for the use of these form release agents. These materials are mostly regulated by EPA.\n\n2. In terms of concrete design, it is apparent that the main effect of diesel is its specific gravity. Diesel has a specific gravity ranging between 0.81 - 0.96 (based on water SG @ 60 deg. F. This means that you would not require as much reinforcement as you would in a tank that would store water.\n\n3. Some waterproofing materials that are used to protect concrete are diesel based. Again, this proves to show that diesel has no degrading effect on concrete.

The basic answer is yes.\n\nThere are several forms of biomass energy. In the realm of liquid fuels (for transportation, for example) you have biodiesel (made from soy or another plant, basically vegetable oil) and ethanol (currently mostly made from corn but in the future also to be made from grasses, crop "waste", etc. These fuels are becoming cheaper and are now getting competitive. For example a 20% blend of biodiesel is probably no more than 5% over regular diesel, and ethanol is competitive with regular octane fuels (at least in the cost of manufacture). \n\nSolid biomass is a good option for mixing in with coal-fired power plants to cut costs and CO2 emissions.

Yes - you use the same tranesterification process used to make biodiesel. React molten, dewatered lard with potassium hydroxide (1%w/v) dissolved in methanol. Allow reaction to proceed to completion. Drain glycerol/free water off. Wash with water, drain and allow to settle till all water is released. Drain again - viola, Biodiesel!\n\nBTW - if you follow Chem Mans advice and hit the lard with potassium hydroxide solution (in water), you will form liquid soap - not oil.

ALL ESTIMATES ARE ROUGHLY\nOil\nSpent in USA\n$100-150 billion every year on crude oil\nUsed in USA\n60 billion gallons of petroleum diesel\n120 billion gallons of gasoline\n\nBiodiesel\n\nTo grow the "feedstocks"\n$80,000 per hectare for algal ponds\n3.85 million hectares of algae ponds would be need to replace all petroleum transportation fuels with biodiesel\n$308 Billion just to build the farms\n\nOperating cost\n$12,000 per hectare\n$46.2 billion per year to yield all the oil feedstock necessary for the entire country\n\nI will add more fuel later must go watch TV now\n***EDIT***\nOk I am back, it turn out that makeing ethanol and biodiesel are around the exact same cost.  But I doubt that they will ever be a realistic source of fuel.\n\n I found this and thought you might find it interesting\n""...but producing ethanol or biodiesel from plant biomass is going down the wrong road, because you use more energy to produce these fuels than you get out from the combustion of these products.""\n\nStudies done everywhere show that cost and disposal of the bi-products are going to be a problem, plus energy wise its just not worth it.  They are working on these problems trying to figure something out to make it more feasible.\n\nIn terms of energy output compared with energy input for ethanol production, the study found that: \n\ncorn requires 29 percent more fossil energy than the fuel produced; \nswitch grass requires 45 percent more fossil energy than the fuel produced; and \nwood biomass requires 57 percent more fossil energy than the fuel produced. \n\nIn terms of energy output compared with the energy input for biodiesel production, the study found that: \n\nsoybean plants requires 27 percent more fossil energy than the fuel produced, and \nsunflower plants requires 118 percent more fossil energy than the fuel produced.

Yes CO2 is produced.\nThis occurs during the 2 oxidative decarboxylation reactions. Isocitrate (6-carbon compound) is decarboxylated to form alpha-ketoglutarate (5-C compound) and subsequently to Succinyl CoA(4-C compound).

Don't fool yourself. They are all liars. Everything is a lie. Biodiesel isn't biodiesel. It's 90% diesel, and 10% soybean methyl ester. The govt makes environmental laws, not for the sake of the environment, but to create jobs, which is not such a bad thing, but this is what the e-check was all about- to make sure no-accounts and convicts getting out of prison had jobs. My job is centered around an environmental industry, but there aren't enough hours in the day for me to be totally compliant. If I had one more person to work with, I could. Our product also contributes to pollution, so you see, it's bs.

I like the idea of Bio fuel, you can make a low octane fuel from all kinds of agricultural bi-products. We happen to be really good at agriculture

It won't be there, and there is no satisfactory alternative.  Biofuels are a fantasy.  Try running your car on wind, coal or nuclear power.  \n\nGone is gone.  It's like money in the bank.  After you spend it all, there ain't no more.

To Prove to the Right People that My Compact, Safe, Low Pressure Unit can Turn Regular Pump Gasoline into Propane. I've already Accomplished it. The Problem is the Fact that all Vehicles from 1996 to the Present are Required by the Stringent EPA  OBD II Law to Run at 14.7 Parts of Air to 1 Part of Fuel, or the vehicle will Fail Inspection . Even if Fuel Economy is Markedly Improved, and Emissions Lowered, the Vehicle will fail Inspection because by Law, there is a maximum, and a Minimum Limit. Deviate from Either Parameter and the Vehicle will Fail Inspection. This is Insane! I've been to the US Patent Office and Looked at the Patents for Other Similar Units that have been kept off the Market.The Pogue Carburetor, which is Patented, is Documented to Provide 100 + MPG with a Flat-Head Ford V-8 Engine, that's usually 15 MPG, or Less! We have got to Reduce Dependence on Petroleum Worldwide, Vehicle Emissions, and Global Warming. That's the Dream , and the "Why". So, How am I Doing? 14.7 to 1 is the Law. I've Managed to prove 100 to 1 is Possible, but it's a Losing Proposition at this Point. For even More,http://energy21.freeservers.com/bookrep.html Hybird Vehicles aren't the Answer.At Highway Speed, the Gas Engine takes Over, plus the Heavy Batteries have to be Hauled.Cheap, Safe Hydrogen is the Answer, but as long as there is a High level of Profit in Petroleum, nothing will Change, including the insane EPA OBD II Law.So, I'm not doing very well at this Point. Maybe with the Power of the Internet that will Change.
