摘要: The present invention provides a process for desulfurizing gasoline fraction by solvent extraction: introducing the gasoline fraction into an extraction tower at a lower-middle part thereof, introducing a solvent into the extraction tower at the top thereof, injecting saturated C5 hydrocarbon into a reflux device at the bottom of the extraction tower, wherein the gasoline fraction which is desulfurized flows out from the top of the extraction tower; the solvent that has extracted sulfide, aromatics and C5 hydrocarbon flows out from the bottom of the extraction tower, and is separated into a C5 hydrocarbon-containing light component, a sulfur-rich component, water and the solvent. The present invention also provides a process for deeply desulfurizing catalytic cracking gasoline, which flexibly combines the process described above and an existing desulfurization technology.

摘要: The present disclosure provides an aromatization catalyst, a preparation method, a regeneration method and an aromatization method thereof. The preparation method comprises steps of: mixing a zeolite molecular sieve with a binder to obtain a catalyst precursor; the catalyst precursor is successively subjected to an ion exchange modification and a first modification treatment, and then subjected to a hydrothermal treatment, and further subjected to active metal loading and a second modification treatment, to obtain the aromatization catalyst. The aromatization catalyst has good carbon deposition resistance and high aromatization activity, and enables an aromatization reaction to be completed under mild conditions, and has high aromatic selectivity, and the liquid yield is above 98.5%.

摘要: A method for upgrading fluid catalytic cracking gasoline includes the following steps: cutting fluid catalytic cracking gasoline into light, medium, and heavy gasoline fractions; subjecting the medium gasoline fraction to an aromatization/hydroisomerization reaction in the presence of a catalyst to obtain a desulfurized medium gasoline fraction; and blending the light gasoline fraction, the desulfurized medium gasoline fraction and the heavy gasoline fraction to obtain upgraded gasoline; where, a cutting temperature of the light and the medium gasoline fractions is 35-60° C., and a cutting temperature of the medium and the heavy gasoline fractions is 70-160° C. The method according to the present invention not only can realize deep desulfurization of fluid catalytic cracking gasoline, but also can improve octane number significantly.
