Abstract

Mainly introduces the development trend of domestic and maleic anhydride, maleic anhydride analysis of industrial production in China and abroad, the gap between the status quo of China's maleic anhydride industrial development proposals. Outlined in the body of n-butane as the raw material, fixed bed, organic solvent recovery process of the production of maleic anhydride and at the same time introduced the use of industrial fixed bed butane oxidation is the process characteristics and processes, and fluidized bed technology and compared, and finally come to the conclusion: the use of n-butane production of Oxidation technology have great advantages and development prospects, not only rich in raw materials, and reduced costs as part of the driving force.

[Key words] Maleic anhydride N-butane fixed bed fluidized bed Oxidation
