No. 36 Effect of reaction parameters on gasification rate and H_2/CO ratio of synthesis gas produced by catalytic steam gasification of HyperCoal

Abstract

Effect of steam partial pressure on reaction rate and on composition of the gas produced from catalytic steam gasification of HyperCoal has been investigated. The parameters investigated were gasification temperatures 700, and 750℃, catalyst loading 50wt%, and steam partial pressure 0.5, 0.1 and 0.02atm. By changing partial pressure of steam, synthesis gas with desired H_2/CO ratio was obtained. Gasification rates were high. The results showed that synthesis gas suitable for DME, methanol and methane production by FT synthesis process can be produced in a single step at 700℃ by catalytic steam gasification process.
