43. H_2 production by catalytic steam gasification of HyperCoal

概要

論文の詳細を見る
HyperCoal is a solvent extracted coal with ash content <0.1%. Catalytic steam gasification of HyperCoal was carried out at 650-775℃ for production of H_2 and synthesis gas. The gasification results showed nearly 4 times higher gasification rate than raw coal. Deactivation of the catalyst was not observed even after 6 times recycling of the same catalyst amount. H_2/CO ratio was reduced from 10.5 to 1.4 by changing the partial pressure of steam. The preliminary results showed that HyperCoal, an ash less coal, could be a potential hydrocarbon resource for H_2 and synthesis gas production by catalytic steam gasification process.
