TLDR
In this paper, various Group I metal salts such as K 2 CO 3, Na 2 CO3 and borax are used as catalysts for coal-to-steam hydrogen reaction.Abstract:
Coal is catalytically reacted with steam to produce hydrogen. Various Group I metal salts such as K 2 CO 3 , Na 2 CO 3 and borax are used as catalysts. These catalysts are stabilized with fluoride containing salts such as CaF 2 to thereby extend their life. Alternatively, NaF was found to be a thermally stable catalyst for the reaction.read more
