Abstract (en)
[origin: EP0314992A2] In the process for the hydroconversion of heavy and residual oils, spent and waste oils mixed with sewage sludges in a typical liquid-phase hydrogenation with hydrogen-containing gases with addition of a finely ground material, this additive preferably has a large internal surface area. <??>Industrial and also municipal sewage sludges frequently contain problematic constituents which preclude disposal by application to fields in agriculture or landfill or by combustion and pyrolysis processes. <??>The additive is added in two different grain size ranges, in such a way that a part of the additive is a fine-grained fraction having a grain size of 90 mu m or less and another part is a coarse-grain fraction of a grain size from 100 mu m to 2000 mu m, preferably 100 to 1000 mu m, and that the process is carried out at a weight ratio of the feed oils and the sewage sludges used of 10 : 1 to 1 : 1.5. <??>The process is used for converting the vacuum residue from a Venezuelan heavy oil with addition of 2% by weight of lignite coke as an additive and admixing of 10% by weight of sewage sludge in a liquid-phase hydrogenation to obtain, in particular, useful liquid products and extensive conversion of the organic fractions of the sewage sludge.
