Shanghai Yuan olefin isomerization catalyst realized industrial application

Recently, DBI-1 ultra-selective olefin double-bonding catalyst independently developed by Shanghai Petrochemical Research Institute has achieved its first industrial application
in the 20,000 tons/year polymerization grade 1-butene production unit of Ningxia Coal Industry of China Energy Group.
Up to now, the catalyst has been running stably for two cycles, with excellent performance indicators, and has been highly recognized
by enterprises.

With the acceleration of the transformation and upgrading of China's refining and chemical enterprises, high-end and refined carbon IV value-added utilization technology has attracted more and more attention, and the related technology market and catalyst application have also shown an upward trend
.
Double bond isomerization catalysts have the advantages of ultra-high selectivity of target products and simple product separation, but the problems of easy inactivation and poor stability limit their wide application
in industry.
Previously, only one foreign company realized the industrial application
of this type of catalyst.
The application of DBI-1 ultra-selective olefin double-bond isomerization catalyst broke the monopoly of foreign catalysts in the field of butylene double-bond isomerization, and realized the localization of ultra-highly selective double-bond isomerization catalyst
.

After several years of research, the technical team innovated the catalyst surface defect control technology, significantly improved the effective active site density of the catalyst surface, and overcame the problem
of poor catalyst stability.
During the catalyst commissioning period, the technical team of Shanghai Academy overcame the impact of the epidemic, actively communicated with the owner through video conference, email and other means, remotely assisted in the filling, activation and feeding of the catalyst, and guided the optimization of the catalyst operation plan
