ABSTRACT:
Process for the hydrogenative conversion of heavy oils and residual oils, used oils and waste oils, mixed with sewage sludge in a typical liquid phase hydrogenator with gases containing hydrogen, with the addition of a finely ground substance that preferably has a large internal surface area, as additive. The additive is added in two different particle size ranges so that a portion of the additive is present as a fine particle size fraction iwth a particle size of 90 .mu.m or less and another portion as a coarse particle size fraction with a particle size of 100 .mu.m to 2000 .mu.m, preferably 100 to 1000 .mu.m with the procedure being carried out with a weight ratio of raw oils to sewage sludge used of 10:1 to 1:1.5. Conversion of vacuum residue of a Venezuelan heavy oil with the addition of 2 wt. % of lignite coke as additive and with the admixture of 10 wt. % industrial or municipal sewage sludge in a liquid phase hydrogenator to obtain useful liquid products in particular, and extensive conversion of the organic fractions of the sewage sludge.
