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 hydr ...
