Hydrotreating - slurry using a supported catalyst slurry to improve the quality of heavy oil

摘要

The method comprising the presence of a supported metal catalyst and a hydrogen-containing treatment gas, can be treated with a slurry hydrogenation conditions a hydrocarbon feedstock, to obtain a product stream of the first containing feed stream which has been hydrotreated and the catalyst, The supported metal catalyst is a sulfide, which is supported on a metal selected from the group consisting of mixtures of these non-noble Group VIII metal, and Group VIB metals, and an inorganic oxide, the carrier, the catalyst The steps have an average diameter of about 0.5 to about 100μm; least one stream comprising said catalyst; and separated into a stream containing the catalyst and the product stream does not contain the catalyst, the product of the first Slurry hydroprocessing method comprising the step of recycling back to the hydrogenation process, the part (SHP) is disclosed.
