GAS?
Uses: Methane – meth – CH4 is a colorless, flammable, nontoxic gas with a sweet, oil type odor.
Methane is useful in the testing of gas appliances which are to be used for natural gas areas. It is
one of the raw materials used in the production of ethanol, methyl chloride, methylene chloride, and
is also used to produce ammonia and actylene. High purity mathane is burned to form a high quality
carbon black which is used in a variety of electronic components.
Methane also is produced industrially by the destructive distillation of bituminous coal in the
man-ufacture of coal gas and coke-oven gas. The activated-sludge process of sewage disposal
also produces a gas rich in methane.
Methane is the simplest member of the paraffin series of hydrocarbons. Its chemical formula is
CH4. It is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in
water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly
luminous, and very hot. The boiling point of methane is -162.0° C (-259.6° F) and the melting
point is -182.5° C (-296.5° F). Methane in general is very stable, but mixtures of methane and air,
with the methane content between 5 and 14 percent by volume, are explosive. Explosions of such
mixtures have been frequent in coal mines and collieries and have been the cause of many mine
disasters.
The chief source of methane is natural gas, which contains from 50 to 90 percent methane,
depending on the source. Methane produced by the destructive distillation of bituminous coal and
by coal carbonization is important in locations where natural gas is not plentiful.
Since commercial natural gas is composed largely of methane, their uses may for all practical
purposes be considered identical. Because of its abundance, low cost, ease of handling, and
cleanliness, such gas is widely used as a fuel in homes, commercial establishments, and factories.
Methane is an important source of hydrogen and some organic chemicals. Methane reacts with
steam at high temperatures to yield carbon monoxide and hydrogen; the latter is used in the
man-ufacture of ammonia for fertilizers and explosives. Other valuable chemicals derived from
methane include methanol, chloroform, carbon tetrachloride, and nitromethane. The incomplete
combustion of methane yields carbon black, which is widely used as a reinforcing agent in rubber
used for automobile tires.
And yes it is used in tractor pulls and some dragsters.It is changed to nitromethane.
