The coal gasification process includes the reaction of coal feedstock, prepared in either a dry or slurried form, with steam and oxygen at high temperature and pressure in a reducing atmosphere. The synthesis gas is then used to produce electricity, liquid fuels, methane gas, or chemicals. Coal Gasification means methane or other commercial coal.
