Abstract

The invention relates to a hydrocarbon oil desulfurization catalyst containing an FAU structural molecular sieve, a preparation method of the hydrocarbon oil desulfurization catalyst and a hydrocarbonoil desulfurization process. Based on the weight of the hydrocarbon oil desulfurization catalyst or the total weight of a sulfur storage metal oxide, an inorganic oxide binder, boron nitride, the FAUstructural molecular sieve and a metal accelerant, the hydrocarbon oil desulfurization catalyst contains 10-80wt% (calculated by oxides) of sulfur storage metal oxide, 3-35wt% (calculated by oxides)of inorganic oxide binder, 5-40wt% of boron nitride, 1-20wt% (calculated by dry bases) of FAU structural molecular sieve and 5-30wt% (calculated by metal elements) of metal accelerant. When being applied to the hydrocarbon oil desulfurization process, the hydrocarbon oil desulfurization catalyst provided by the invention has the advantages of high stability, good desulfurization activity and goodwear resistance.

Description

technical field [0001] The invention relates to a hydrocarbon oil desulfurization catalyst containing molecular sieve with FAU structure, a preparation method thereof and a hydrocarbon oil desulfurization process. Background technique [0002] With the increasing scarcity of crude oil resources, how to effectively utilize limited resources to produce light products in a large amount has become the goal pursued by refinery technology developers. On the other hand, with the continuous improvement of environmental protection requirements, environmental protection regulations are becoming increasingly strict. The current gasoline quality standard GB17930-2013 requires that the sulfur content in gasoline must be less than 10ppm from January 1, 2017. Therefore, the clean product production technology that can simultaneously increase the yield of the target product has become the choice of many refiners. [0003] In my country, catalytic cracking has been widely used due to its go...
