The catalyst activity problem is solved

"The catalyst activity problem that plagued the production of the factory has finally been solved.
At present, the octenal hydrogenation catalyst has reached the ideal standard in the production process of octanol
.

It is understood that the butanol unit of the Jilin Petrochemical Fertilizer Plant has been using the octenal hydrogenation catalyst developed by the Jilin Petrochemical Research Institute to produce octanol for more than 20 years, but the activity of the catalyst has been reduced during the production process
.

In order to solve the catalyst activity problem, the Jilin Petrochemical Research Institute organized scientific researchers to start with the determination of the hydrogen temperature programmed reduction peaks of the two batches of catalysts
.

According to reports, the low-temperature reduction peak of the catalyst is the reduction peak of the highly dispersed active components of the catalyst, and the lower the reduction temperature, the higher the dispersion of the active components of the catalyst, and the stronger the catalyst activity
.

In the process of solving the problem, the backbone of scientific research Lu Jianhui modified the existing automatic chemical adsorption instrument in the institute, established a hydrogen temperature programmed reduction measurement method, and completed the hydrogen temperature programmed reduction analysis of two batches of catalysts with the research team
.

"Without specific data on the degree of dispersion, it is difficult to have a definite conclusion
.

After the ball mill is replaced, the catalyst activity returns to normal, and the octenal hydrogenation catalyst to produce octanol unit will achieve full-load production
