On November 16, 2017, the project of "Development and Industrial Application of Butadiene Oxidative Dehydrogenation to Butadiene" independently researched and developed by Wison Engineering Co., Ltd. passed the technology organized by China Petroleum and Chemical Industry Federation in Beijing Results identification.
The identification by the China Petroleum and Chemical Industry Federation, Ministry of Science and Technology Director Jiang Yanru presided over the Chinese Academy of Engineering, Professor Jin Yong appointed Tsinghua appraisal committee director, members from East China University of Technology, the Branch Synthetic Oil Technology Co., Ltd., Tianjin University , Peking University, China Fifth Ring Engineering Co., Ltd., Beijing University of Chemical Technology and other famous enterprises and university experts.China Petroleum and Chemical Industry Federation, Deputy Director of Science and Technology Hu Juan also attended the meeting.
Expert Appraisal Committee fully affirmed the Wison project of technological innovation, that: 'butadiene oxidative dehydrogenation of butadiene technology and catalyst development and industrial applications as a whole the results of the international advanced level, in which a new type of butane oxidation of the catalyst product The yield is at the leading level in the world and unanimously passed the appraisement 'and suggested that' speed up the popularization and application '.
Jin Yong academician said: "butadiene oxidative dehydrogenation of butadiene technology has been developed for more than 50 years, but due to production costs, has not been well promoted and applied.Wisconsin engineering in the past on the basis of technical achievements, in the A great deal of technological innovation has been carried out on the catalyst and the process, the energy consumption and the production cost have been reduced effectively, and the technology has good application prospect.
Wison engineering research and development of butadiene oxidation butadiene dehydrogenation technology butadiene using two fixed-bed process and Wison heat research and development of new catalysts, in a single production line to achieve production capacity of 100,000 tons / year at the same time the conversion of butene up 80%, butadiene selectivity of about 93%, the yield of more than 74%; part of the separation using NMP or improved ACN technology can significantly reduce the device investment and energy consumption.This technology also includes suitable for large-scale reactor technology, Plant waste water reuse, online catalyst regeneration and other innovative technologies.At present, the scientific and technological achievements have been in Shandong Heze Jade Chemical Co., Ltd. butadiene plant industrial success, and achieved significant economic and social benefits, and once again authorize Nanjing Chengzhi Yongqing Energy Technology Co., Ltd. 100,000 tons / year butadiene plant.
Liu Haijun, President of Wison Engineering, said: "We are very grateful to Jin Yong Academicians and Panels for their approval of Wison Oxidative Dehydrogenation Technology, which is a recognition, encouragement and encouragement for Wison's R & D work. Wison Engineering will continue its efforts In the clean energy, green chemical technology research and development, China's chemical technology innovation to make its own contribution.
Butadiene is an important basic chemical raw material, with the global light olefin raw materials, conventional ethylene plant cracked C4 tetrabutadiene extraction of the amount of butadiene monomer will be significantly reduced, the global supply of butadiene The problem will be solved by specialized butadiene production technology. Butadiene oxidation and dehydrogenation production of butadiene technology is one of the solutions. Wacky Butadiene oxidation and dehydrogenation of butadiene technology through the optimization of catalyst and process technology, production costs Can be used as an effective complement to the butadiene by-product of ethylene and contribute to the diversification of raw materials for butadiene production.Under the current high coal prices, this technology can be used for the co-production of coal-to-olefins Comprehensive utilization to produce high value-added butadiene monomer, substantially enhance the overall efficiency of MTO plant, has a good promotion prospects.
