This patent describes an integrated coking and hydroconversion process. It comprises: treating a hydrocarbonaceous feed having a Conradson carbon content of at least 5 weight percent in a coking zone maintained under fluidized coking conditions, including a pressure ranging from zero to about 100 psig, to produce coke and a vapor phase product, including hydrocarbonaceous comprising constituents boiling above 975 {degrees} F; passing the vapor phase product to a scrubbing zone; separating a heavy bottoms fraction in the scrubbing zone having a Conradson carbon content of at least about 5 weight percent, including the constituents boiling above 975 {degrees} F, from the hydrocarbonaceous material; passing the heavy bottoms fraction through a microfiltration system thereby resulting in a solids laden fraction and a hydrocarbonaceous filtrate; recycling at least a hydroconversion catalyst or hydroconversion catalyst precursor to at least a portion of the hydrocarbonaceous filtrate; subjecting at least a portion of the mixture to hydroconversion conditions to produce a hydroconverted oil; passing the hydroconverted oil to a microfiltration system wherein solids suspended in the hydroconverted oil are removed; and passing the filtrate resulting from the filtration to a liquid-liquid separation wherein the resulting heavy fraction is recycled to the coking zone.
