A catalyst for use in a process for steam conversion of a heavy hydrocarbon feedstock includes the steps of: providing a heavy hydrocarbon feedstock; providing a catalytically active phase comprising a first metal and a second metal wherein said first metal is a non-noble Group VIII metal and said second metal is an alkali metal; and contacting said feedstock with steam at a pressure of less than or equal to about 300 psig in the presence of said catalytically active phase so as to provide a hydrocarbon product having a reduced boiling point. The catalyst may be supported on a support material or mixed directly with the feedstock and comprises a first metal selected from the group consisting of non-noble Group VIII metals and mixtures thereof and a second metal comprising an alkali metal wherein said catalyst is active to convert said heavy hydrocarbon at a pressure of less than or equal to about 300 psig.

Un procédé catalytique de conversion à la vapeur d'une alimentation d'hydrocarbures lourds comprend les étapes suivantes : partir d'une alimentation en hydrocarbures lourds; obtenir une phase catalytiquement active, renferment un premier métal, à savoir un métal non précieux du Groupe VIII, et un second métal, soit un métal alcalin; mettre en contact ladite alimentation avec de la vapeur à une pression inférieure ou égale à environ 300 lb/po2, en présence de ladite phase catalytiquement active, de façon à obtenir des hydrocarbures à point d'ébullition plus bas. Le catalyseur, sur une matière de support ou mélangé directement avec l'alimentation, comprend un premier métal, choisi dans le groupe constitué des métaux non précieux du Groupe VIII et de leurs mélanges, et un second métal, à base d'un métal alcalin; ledit catalyseur permet de convertir activement lesdits hydrocarbures lourds à une pression inférieure ou égale à environ 300 lb/po2.
