摘要： The present invention is drawn to a process for the production of anode grade coke from a hydrocarbon feed characterized by high levels of sulfurs and metals. The hydrocarbon feed is hydrocracked in a hydrocracking reactor so as to produce an overhead effluent which is fed to a hot separator wherein a light hydrocarbon stream and a slurry hydrocracked product are produced. The hydrocracked product is fed to a separator and mixed with a solvent wherein the solids are separated out from the hydrocracked residual so as to produce a clean hydrocracked residual which is fed to a coking drum and coked so as to leave a mass of green anode grade coke.

摘要： The present invention relates to a combined process for separating and converting asphaltenes of high molecular weight and high softening point from heavy hydrocarbon material containing asphaltenes by a process that combines a deasphalting method to produce solid asphaltenes and a continuous coking procedure for the solid asphaltenes. The combined process converts the material into more valuable liquid hydrocarbon products of lower molecular weight and coke.
