Coal Gasification Research @ RGD Lab, MiT

2017-10-3  Gasification is defined as the process of reacting a carbon-rich feedstock (coal, petroleum coke, biomass, waste, etc.) with steam and oxygen to form a synthesis gas containing H2 and CO. It can be viewed globally as extremely rich combustion and usually utilizes solid or liquid feedstocks.
