Sinopec University of Petroleum (East China) signed an adiponitrile project

　　Recently, Associate Professor Wang Bo from the School of Chemistry and Chemical Engineering, China University of Petroleum (East China) signed an agreement on the development of a complete set of technologies for the production of adiponitrile by butadiene hydrocyanation with a refining and chemical company under Sinopec, which officially started.
The technology is transformed into industrial applications
.

　　Adiponitrile is the main raw material of the nylon industry chain, and it belongs to China's "stuck neck" product, which has become a major bottleneck restricting the development of nylon 66 industry
.
The innovative production process of adiponitrile developed by Wang Bo has independent intellectual property rights, and has a complete technical process package for the direct cyanation of butadiene and hydrocyanic acid to produce adiponitrile, including the whole process technology, equipment design, process safety protection, Online analysis and detection,
etc.
He also developed a complete set of production technology for the production of hydrocyanic acid by ammonia oxidation of methanol, and invented the industrial on-line detection technology of hydrocyanic acid, which has a cost advantage compared with the American natural gas Angstrom method
.
In terms of catalyst system, Wang Bo has developed a highly active and highly selective metal-organic catalyst system for the reaction of butadiene and hydrocyanic acid to produce adiponitrile, which realizes the efficient recovery and recycling of the catalyst
.

　　This technology breaks through the technical barriers existing in catalytic system, reactor, separation and purification, equipment selection and so on
.
Compared with the existing adipic acid ammoniation method and acrylonitrile electrolysis method in the industry, this technology has significant advantages such as higher yield, lower cost, and environmental friendliness
.
At present, this innovative production process of adiponitrile has completed the verification of a modular continuous small-scale industrial demonstration unit
.
After reviewing by experts organized by Sinopec, it was agreed to start the construction project of 10,000-ton industrial production equipment
.

　　When evaluating the technology, Gilbert F.
Froment, academician of the American Academy of Engineering and world leader in the field of reaction engineering, said: "The technology developed by Wang Bo to prepare hydrogen cyanide by ammonia oxidation of methanol uses methanol as raw material to develop a highly active and selective composite metal oxidation technology.
It has low reaction temperature, energy saving and environmental protection, and the yield of hydrocyanic acid is significantly higher than that of the Anson method
.
The overall energy consumption of this complete set of technical devices is low, which can effectively reduce construction investment and operating costs, and has great advantages.
good industrial application value
