Abstract
Methods and apparatus relate to processing of petroleum with a bed having a sorbent based diluent that the petroleum contacts upon passing through the bed. Magnetic properties of the sorbent and any other material, such as zeolite, used in the bed enable separation of such bed constituents based on a sulfided form of the sorbent being magnetic in contrast to a non-sulfided form of the sorbent being non-magnetic. Dividing the bed constituents into first and second portions by magnetic separation facilitates in selective replacing and/or regenerating the first portion independent of the second portion.
Claims13
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.
