Dalian Institute of Chemical Physics Chinese Academy of Sciences and Shandong Union Chemical Limited by Share Ltd to cooperate in the development of the key technology of methanol ethanol methanol phase carbonylation of methyl acetate in test technology research results through the identification of the China petroleum and chemical industry association in Beijing.
Ethanol is not only an important solvent and chemical raw material, but also an ideal non polluting high octane number vehicle fuel and additives. Methanol / multi phase carbonylation synthesis gas and its hydrogenation to ethanol technology to meet the requirements of current industrial layout in China, has great technical and production cost advantages, and methanol phase carbonylation of methyl acetate technology is the key technology of the technology route.
Deputy director of the Ministry of science and technology expert Wang Xiujiang presided over by the Federation of petrochemical, taking Fudan University Zhao Dongyuan as director of the appraisal committee listened carefully to the technical research report Dalian Institute researcher Ding Yunjie, review of the relevant test report, report and other relevant information, agreed that the technology innovation ability, has the good economic expectations and social benefits, technical indicators have reached the international advanced level.
Ding Yunjie led the research team developed with high dispersion, high activity, high ivity and high stability of the methanol phase carbonylation of methyl acetate Ir-La based catalyst, effectively reducing the methanol carbonylation reaction phase separation cost and loss of precious metals. Through the use of Ir-La based catalyst for methanol conversion and control, and the use of Hastelloy tube in iodine carbonylation system, successfully reduce the project investment and production cost, the total space time yield of methyl acetate and acetic acid reached 3-5kg/kgcat.h, new technology to achieve a multi phase methanol carbonylation of methyl acetate.
