Clean catalyst for benzene alkylation to ethylbenzene

Recently, the research team of Shanghai Research Institute of Petroleum and Chemical Industry has developed a clean production technology for the gas-phase benzene alkylation to ethylbenzene catalyst, which can effectively reduce the "three wastes" emissions in the catalyst production process
.
? The scientific research team successfully synthesized ZSM-5 molecular sieve with high crystallinity and small crystal particles under sodium-free conditions, reducing the amount of template agent by more than 70%, and at the same time eliminating the ammonium exchange step.
The production of 1 ton of catalyst can avoid the production of 60 tons of ammonia.

.
The technology was expanded for industrial testing in September this year, and the whole process of the clean production technology of the catalyst for the production of ethylbenzene from benzene alkylation was opened up
.
It only took one and a half years from laboratory research to industrial production .
