Natural gas is a fossil other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. There are several different theories to explain how fossil fuels are formed. The most prevalent theory is that they form underground, under intense conditions. As plants, animals, and microorganisms decompose, they are ...

In this process, coal is combined with oxygen and steam to produce a combustible gas, waste gases, char, and ash. The more than 70 coal gasification systems available or being developed in 1979 can be classified by the heating value of the gas produced and by the type of gasification reactor used. HighBtu

Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal. Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and nitrogen.

A synthesis gas can also be created by reacting coal or biomass with hightemperature steam and oxygen in a pressurized gasifier. This converts the coal or biomass into gaseous components—a process called gasification. The resulting synthesis gas contains hydrogen and carbon monoxide, which is reacted with steam to separate the hydrogen.

The amount of CO 2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content or the amount of energy produced when a fuel is burned is mainly determined by the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and H combine with oxygen (O) during combustion. Natural gas is primarily methane (CH 4), which has a higher energy content ...
