PROCESS FOR HYDRODESULFURIZATION OF CARBONACEOUS STOCKS USING SUSPENDED CATALYST ABSTRACT OF THE DISCLOSURE A solid, sulfur-containing carbonaceous feedstock, e.g. coal or other high carbon content solid, in a finely divided form is suspended in a hydrocarbon liquid along with a finely divided hydroconversion catalyst having a nominal particle size of less than about 10 microns. The resulting suspension and a hydrogen- containing gas are contacted at an elevated temperature and pressure and at a weight hourly space velocity of between 200 and 50,000 kg. of the suspension per kg. of catalyst per hour. The resulting product is continuously withdrawn from the contact zone and normally gaseous materials are separated. A liquid product having a substantially reduced sulfur content and containing the finely divided catalyst is recovered as desulfurized product. -1-
