Embodiment 1

[0020] With 1000 grams of silicon-aluminum ratio being 26 hydrogen type zeolite beta (produced by Zhuozhou Nanda Catalyst Co., Ltd.), getting commercially available silicon-alumina ratio is 1500 grams of HZSM-5 molecular sieve of 60, 0.6M Ce 2 (SO 4 ) 3 800ml of the solution was exchanged. That is, at 40°C, rapidly stir and exchange for 2 hours, then filter the slurry, dry at 110°C for 2 hours, crush and exchange again. After being dried and pulverized, modified zeolite beta A was obtained, wherein the content of cerium was 2.2%, and it was ready for use.

Embodiment 2

[0022] 1000 grams of HY zeolite (produced by Zhuozhou Nanda Catalyst Co., Ltd.) with a silicon-aluminum ratio of 4 were mixed with 0.6M LaCl 3 600ml of the solution was exchanged. That is, at 40°C, rapidly stir and exchange for 2 hours, then filter the slurry, dry at 110°C for 2 hours, crush and exchange again. After drying and crushing, La-modified Y zeolite B was obtained, wherein the La content was 1.5%, which was ready for use.

Embodiment 3

[0024] 1000 grams of hydrogen-type beta zeolite (produced by Zhuozhou Nanda Catalyst Co., Ltd.) with a silicon-aluminum ratio of 26 was exchanged with 800 ml of a 0.2M rare earth chloride solution. That is, at 40°C, rapidly stir and exchange for 2 hours, then filter the slurry, dry at 110°C for 2 hours, crush and exchange again. After being dried and pulverized, modified zeolite beta C is obtained, wherein the mixed rare earth content is 0.6%, which is ready for use.

Abstract

The invention discloses a catalyst, in particular an alkylation catalyst. Aiming at the problems of high activity lowering speed and short service life in the use process of the alkylation catalyst in the prior art, the invention provides a novel alkylation catalyst comprising 2-98wt% of modified zeolite and 98-2wt% matrix material weighted on the basis of the total weight of the catalyst; the modified zeolite is one or more of H-Y zeolite, hydrogen USY-zeolite and hydrogen beta-zeolite; the matrix material consists of a component A, a component B and a component C, wherein the component A is aluminum oxide, the component B is aluminum phosphate and the component C is any one of silicon dioxide, titanium dioxide, zirconium oxide and clay. Compared with the prior art, the alkylation catalyst has stronger alkylation reaction performance and stability and has the advantages of capability of increasing the conversion rate of alkylation isoparaffin , no hydrogen consumption, no noble metals and long service life; and a device is easy to operate.

Description

technical field [0001] The present invention relates to a catalyst, in particular to an alkylation catalyst. Background technique [0002] At present, all countries attach great importance to the protection of the environment on which human beings live. Among them, air pollution is one of the problems that need to be solved urgently. With the development of economy and the rapid development of transportation, vehicle exhaust emissions are one of the main sources of air pollution. Improve the quality of gasoline. There is no delay. Compared with European and American countries, my country's gasoline has the characteristics of high olefin content, low aromatic content and high sulfur content, which makes it difficult to meet the increasingly stringent gasoline standards. Adding environmentally friendly gasoline blending components is one of the effective ways to improve gasoline quality. [0003] The alkylated oil produced by the alkylation reaction of isobutane and butene i...
