Here is what I would suggest.  First let the water stand still for a while to settle heavy particle as sand, pebbles, rocks etc.  Then using coffee filter or thick paper towel, decant water.  That should take care of smaller stuff.  Then you use fine powder charcoal and add to your water (filterate).  Let it sit for 10 minutes and stirr occasionally.  Then filter the water using coffee filter or paper towel and you will have odor free-clear, very pure (~ 99%+ water) that can be used for drinking.  If you want absolute pure, before charcoal step, heat the water to boil, cool and then do charcoal step and you will have killed all bio organisms also.

Coal is not actually a compound, but rather a mixture of compounds and so it does not have a chemical formula.\n\nHowever depending on the type of coal, it is composed of between 50-100% carbon, by mass, with the rest being Hydrogen, Nitrogen, Oxygen, and trace amounts of Sulfur. \nLignate has the lowest carbon content followed by sub-bituminous coal, bituminous coal, and finally anthracite which is almost pure carbon.

They burn the coal.\nThe heat generated by burning the coal is used to boil water.\nThe water turns to steam.\nThe steam turns a turbine.\nThe turbine is connected to a magneto.\nThe magneto generates electricity.\n\nViola!

Diamonds and coal have the same basic component, carbon.  Diamonds have been turned into their current form due to extreme pressure and temperature.  Diamonds come from diamond mines, not coal mines.

Coal is a fossil fuel extracted from the ground by underground mining or open-pit mining (strip mining). It is a readily combustible black or brownish-black sedimentary rock. It is composed primarily of carbon along with assorted other elements, including sulfur. Often associated with the Industrial Revolution, coal remains an enormously important fuel and is the largest single source of electricity world-wide. In the United States, for example, the burning of coal generates 50% of the electricity consumed.

heat the pure gas in a sealed tube in absence of air. it breaks up into its components. you've got solid yellow sulphur.

Coal is formed by decomposition of wood.

Commercially:\n=============\nFractional distillation of liquified air. This method involves:\n\n1. Liquifying air which is mostly Oxygen and Nitrogen\n2. Heating liquid air.\n3. Cooling at different temperatures to collect different gases.\n\nOne of the major bi-products of this method is Nitrogen. \n\nLaboratory:\n===========\nHeating some oxide in presence of a catalyst or electrolysis.

Yes, it is bituminous (the only type in the state), if indeed you are talking about soft coal.

Charcoal powder will burn very well.\nThe flame used to ignite the powder will not be affected and will not change color.\nThe charcoal dust will burn yellow/white.  It will be that color because your experiment lacks enough oxygen for it to burn blue.\n\nOther dusts are very flammable and sometimes are explosive.  The dust from grain when stored in a silo is extremely flammable. Silos across the country explode every year.\nCoal is crushed into dust and blown into the furnaces at electrical power plants.  The heat makes steam for the turbine/generators.  \n\nI would like to suggest some experiments with common powders to see how well they burn.  But I singed the hair off both hands, my brother singed off his eyebrows, and we decided playing with fire was (though great fun) rather stupid.

You don't need a chemical reaction.\nFrozen carbon dioxide, known as dry ice, can do the job.\nIt's in a thermos container, but as soon as it touches the air, it sublimates into gaz, producing the smoke. (To make more, put it in water instead.)  And it's heavier than air, so it stays close to the ground.  And it's not expensive!

are you asking how to make it?\n\nfirst make pig iron in a furnace using\n- manganese \n- silicon \n- carbon \n- phosphorous \n- sulphur \n- etc \n\nthen you:\n1. Charge (pour in) scrap iron \n2. Pour in molten (pig) iron \n3. Add lime \n4. Run the furnace \n5. Tap the furnace to remove the steel - care must be used not to pour the slag on the surface \n6. Pour off the slag off \n\nthe second link below gives companies that sell steel.

Can you give more info?  There seems to be much info on making fuels by this method, but nothing on quenching.
