Abstract
A desulfurization system employing a system of fluidizable and circulatable solid particles to desulfurize a hydrocarbon-containing fluid in a fluidized bed reactor. The solid particulate system includes solid sorbent particles operable to remove sulfur from the hydrocarbon-containing fluid stream and solid catalyst particles operable to enhance the octane of the resulting desulfurized hydrocarbon-containing fluid stream. The solid particulate system can be circulated between a reactor, regenerator, and reducer, to thereby allow for substantially continuous desulfurization in the reactor.
Claims19
A solid particulate system comprising an unbound mixture of discrete sorbent particles and discrete catalyst particles, wherein said sorbent particles comprise zinc oxide and a promoter metal component, wherein said catalyst particles comprise a zeolite having a largest ring with at least 10 T-atoms, wherein the weight ratio of said sorbent particles to said catalyst particles is in the range of from about 100:1 to about 4:1, wherein the mean particle sizes of said sorbent particles and said catalyst particles are both in the range of from about 20 to about 200 microns.
