Recently, DBI-1 ultra-selective olefin double-bond isomerization 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.
This application broke the monopoly of foreign catalysts in the field of butene double bond isomerization, and realized the first localization of ultra-high selective double bond isomerization
catalysts.
At present, the catalyst has achieved long-term stable operation of the industry, and the performance indicators are excellent
.
During the catalyst commissioning, the technical team of the Shanghai Institute overcame difficulties, remotely assisted in the filling, activation and feeding of the catalyst, and guided the optimization of the catalyst operation plan
.
In the next step, the technical team of Shanghai Institute will further strengthen the sense of innovation and provide strong technical support
for the expansion and strengthening of the carbon IV value-added utilization chain.
