ABSTRACT:
A combination process is provided for residua demetalation and desulfurization and resulting coke gasification which comprises contacting said residua with a porous refractory oxide in the absence of added hydrogen, at a temperature of from greater than 700.degree.F to about 1100.degree.F and a refractory oxide to oil weight ratio of from about 0.1 to about 5 to produce upgraded residua of cracking feed quality, and contacting said refractory oxide after an amount of coke has formed thereon with steam and a free oxygen containing gas in which the mole ratio of steam to oxygen is from about 3 to about 5, at a temperature of from about 1000.degree.F to about 1500.degree.F to produce producer gas and regenerated porous refractory oxide for further contacting with residua.
