Mixtures of potassium sulphate and iron sulphate as catalysts for water vapour gasification of carbon. 2. Wettability phenomena and reactions of the catalyst precursors

Controlled atmosphere electron microscopy study of the gasification of graphite by water, hydrogen, and oxygen catalyzed by a nickel/potassium mixture

“…In steam only, CAEM studies of Pt/Ba [17] indicate that this mixture is more resistant to poisoning than the components used independently, and flow reactor studies of Fe(N03)3/Na2(C03) mixtures [18] show that this catalyst is more active than either Fe(N03h or Na2(C03) alone. In wet H2, mixtures of K 2 S0 4 and FeS04 form a molten phase at 650°C and this phase has a higher steady state activity and an improved CH4 selectivity than the components used alone [19].…”
