Jilin Petrochemical overcomes synthesis of ethylbenzene catalyst technology

Sinochem News News on September 8, the catalyst technology developed by Jilin Petrochemical Company for the synthesis of ethylbenzene by liquid-phase alkylation of benzene passed the acceptance by experts organized by the Science and Technology Department of Jilin Province
.

The expert group carefully inspected the technical development site, listened to the report on the implementation of the project by Jilin Petrochemical, reviewed the acceptance data and other related materials, discussed key issues, and concluded that the project has completed the project mandate and evaluation indicators, and agreed to pass the acceptance
.

According to the project leader, Dr.
Li Jing, the project developed a new type of benzene liquid phase alkylation synthesis ethylbenzene catalyst-nano-thin MCM-22 molecular sieve catalyst through the method of compound additives modification, and clarified the preparation process of the catalyst after treatment.
In addition to the reaction process conditions, the raw material impurity control indicators have been determined, the pilot scale-up synthesis pilot study of a 1 cubic meter crystallization kettle has been completed, and the pilot production device of nano-thin-layer MCM-22 molecular sieve has been built, and the catalytic performance has reached the level of imported catalysts
.

The data shows that the MCM-22 molecular sieve catalyst in the synthesis of ethylbenzene, compared with the existing catalysts in the device, the number of fillings is significantly reduced, and the reaction temperature, benzene to ene ratio, material consumption and energy consumption are also reduced.
While saving costs, Increase the production capacity of ethylbenzene and reduce the residual oil by-product
.

Not only that, the MCM-22 molecular sieve catalyst also has the characteristics of stable performance and long operating cycle
.

"If the MCM-22 molecular sieve catalyst is industrialized, it will reduce the energy consumption of the device and increase the production capacity of the device.
It is expected to save 500,000 yuan per ton
