COAL AND NATURAL GAS PRODUCE ETHYLENE AND ETHANOL.
C + CH4
+ $ 170.00/TON = $ 1,300.00/TON
Selling coal as it is, is a huge loss, while converting it to ethylene achieves a profit far better than crude oil
While coal could find only
one market of some power plants, Crude Petroleum liquid fuels brought a lot of prosperity. Coal is a very precious and
abundant natural resource of fuels.
COAL PRODUCE ETHANOL through well known, simple
and efficient process. Like petroleum, coal consists of several components, mainly coke, light oil,
tar and some natural gas. Also like petroleum these components can be separated by pyrolysis (=carbonization, =destructive
The successful scheme to process coal is similar to petroleum, in
which each component is separated first and next processed individually. Unhappily coal processing, was and still
is, misled by the Fischer Tropsh chemical reaction, in which coal, as a whole, is subject to a chemical reaction (with
steam) before separating its components. Fischer Tropsh reaction has destroyed the value of coal.
Imagine that crude petroleum
would be treated by a chemical reaction before its distillation and the separation to its components, such chemical reaction
would have destroyed the value of crude petroleum.
It is needed to imitate the petroleum refining to produce liquid fuels out
of coal. It is also totally unlogic to expect that the reaction of a fuel (COAL) with water (steam)
would be fruitful. ETHANOL is produced out of coke by the following two simple reactions:
1] In an electric furnace coke
is allowed to react with methane to produce ethylene gas.
C + CH4
Coke + Methane
Acetylene is produced by this reaction, a well known reaction, with established technology, and straight forward.
( Encyclopedia of Chemical Technology, Kirk and Othmer, under Acetylene)
2] Next comes the well known acid catalysed
hydration of ethylene to produce ethanol:
H2O = C2H5OH
+ Steam = Ethanol
Two well known technologies.
As for the light oil and tar, they are unsaturated
cyclic compounds which can be saturated by hydrogen over catalysts and converted to Diesel fuel.
