A process for gasifying liquid and solid hydrocarbons by contact at elevated temperature with a novel hydrocarbon gasifying catalyst comprising K.sub.2 O--CaO--Al.sub.2 O.sub.3 containing from about 5 to 15% by weight K.sub.2 O, from about 0.1 to 7% CaO, and from about 78 to 94.9% Al.sub.2 O.sub.3.

Process for gasifying hydrocarbons

Reducing gas of low CH.sub.4 content is produced by cracking a heavy hydrocarbon having a C/H atomic ratio of more than one at 800.degree.-950.degree. C. in the presence of a catalyst comprising at least one metal selected from K, Ni, Co and Mo or at least oxide of said metal, associated with alumina or a silica-alumina composite.
