Abstract

The invention relates to a cracking C5 desulfurization agent composition. The cracking C5 desulfurization agent composition comprises the following components in percentage by weight: 10-98% of first component, 0.1-85% of second component and 0.01-0.5% of third component. The cracking C5 desulfurization agent composition disclosed by the invention has the beneficial effects that on the premise of ensuring the quality of a product, by introducing the desulfurization agent composition, the total sulfur removal rate of the C5 can be greatly improved, the total sulfur content in the product and the desulfurization cost can be reduced, the output of desulfurization reaction products is little, and the desulfurization reaction products can be used as other chemical products, so that the cracking C5 desulfurization agent composition has secondary utilization values and obvious economic benefits and environment-friendly benefits.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a cracking C5 desulfurizer composition. Background technique [0002] Cracking C5 (referred to as C5 fraction) can synthesize many high value-added products, which has become an important aspect of rational utilization of petroleum resources and reduction of ethylene production costs. However, the C5 raw material contains about 10-300ppm of sulfur-containing impurities, usually mercaptan, hydrogen sulfide, carbonyl sulfide, carbon disulfide, sulfide, disulfide and thiophene, etc. The sulfide will not only make the C5 fraction process Catalyst poisoning and equipment corrosion also have a negative impact on the quality and processing and application of C5 products. Especially in recent years, domestic refineries mainly process imported high-acid, high-sulfur and low-quality heavy crude oil, and the sulfur content in the cracked C5 fraction has a tendency to increase gradua...
