Abstract:
1. A method of processing petroleum, comprising: contacting in a reactor a solid particulate mixture with a hydrocarbon-containing feed stream, wherein the solid particulate mixture comprises a sorbent and a catalyst, wherein the sorbent comprises a nickel-containing material impregnated thereon and adsorbs sulfur-containing compounds from the hydrocarbon-containing feed stream, wherein magnetization of the sorbent is increased by adsorbing said sulfur-containing compounds to produce a sulfided sorbent, wherein the catalyst comprises a zeolite and causes reactions that increase octane of the hydrocarbon-containing feed stream; removing at least part of the solid particulate mixture from the reactor to provide a removed portion of the mixture; separating the removed portion by relative magnetization into a first portion comprising the sulfided sorbent and a second portion comprising the catalyst and the sorbent; and processing the first portion independent of the second portion and replenishing the solid particulate mixture within the reactor with at least part of the first portion, at least part of the second portion, or a mixtures thereof.
