Hydrocracking of heavy feeds with dispersed dual function catalyst

摘要

Catalytic hydroconversion of a relatively heavy hydrocarbon residual fraction is effected by adding a thermally decomposable metal compound to the oil, along with an acidic catalyst solid to the oil, and passing the mixture to a hydroconversion zone containing hydrogen at an elevated temperature. Preferred metals are cobalt and molybdenum. Preferred solids are large pore zeolites, silica/alumina, clays and surface activated metal oxides.
