Abstract
A continuous fluidized process for upgrading a heavy liquid hydrocarbon charge-stock containing solid or solid-forming contaminants, e.g., inorganic solids, metals and asphaltenes. The charge is atomized to provide a stream of liquid particles introduced horizontally into a horizontal contacting zone to contact a vertical curtain of fluidized hot solid particles so as to vaporize hydrocarbons in the charge without substantial cracking, the solid particles being solely derived from the contaminants in the charge. The mixture of hydrocarbon vapors and solid particles are rapidly separated, carbon is burned from the separated particles, and the resulting hot solid particles are recycled to the contacting zone. The hydrocarbon vapors are condensed and there is recovered a liquid product having a substantially reduced content of contaminants.
