A heavy hydrocarbonaceous oil feed is hydrogenated in a two-stage process by contacting the oil with hydrogen in the presence of added dispersed hydrogenation catalyst, suspended in the oil, and porous solid contact particles. At least part of the normally liquid product from the first stage is hydrogenated in a second stage catalytic hydrogenation reactor.

A process for hydroprocessing a heavy hydrocarbonaceous oil feed to convert at least a portion of feed components boiling above 350°C. to components boiling below 350°C. comprising: (a) contacting said oil with added hydrogen in a first reaction zone under hydroprocessing conditions, including a hydrogen partial pressure of above 35 atmospheres in the presence of (1) added dispersed hydrogenation catalyst suspended in said oil and containing at least one catalytic hydrogenation component selected from transition metal elements or compounds thereof, and (2) added porous contact particles to produce a first effluent having a normally liquid portion; and (b) contacting at least a portion of the normally liquid portion of said first effluent in a second reaction zone with hydrogen under hydrogenation conditions in the presence of a bed of particulate hydrogenation catalyst, to produce a second effluent.
