Method of making a product more valuable from sulfur-containing crude oil

摘要

Is a lower sulfur concentration was purified or upgrading a high sulfur-containing hydrocarbon oil, I discloses a method for the oil light is the product of high-value therefore more. Method of reacting in the presence of a low pressure hydrogen and a catalyst to oil heavy hydrocarbon the high sulfur, to produce a reaction product stream in which the light oil is collected include the method. To produce a low sulfur petroleum product was further upgraded in order to separate a portion of the reaction product is used as distillate fuels. The upgrading process produces residual oils also suitable for making olefins, asphalt and carbon fibers. Catalyst used in the process of the present invention may include a transition metal-containing compound, a Group V of the periodic table, Group VIII and Group VI and the metal is selected from mixtures thereof.
