✦ Synopsis

Steam reforming of petroleum residues was investigated at 1173 K and atmospheric pressure in a fluidized-bed flow system using a series of alumina-supported catalysts of alkali metal compounds. The catalytic activity increased with decreasing ionization potential of the catalytic alkali metals: Cs > K > Na > Li. Catalysis was elucidated in terms of an oxygen transfer mechanism proposed for the catalysis by alkali metal compounds in graphite-or char-steam reaction.
