高空速高选择性丙烯氧化制丙烯酸工艺探讨

Production of acrylic acid by high selectivity and high space velocity propylene oxidation

在LY-A-9601、LY-A-9602丙烯醛、丙烯酸催化剂工业应用的基础上,兰州化工研究中心开发了PRI0901、PRI0902高空速、高选择性丙烯醛、丙烯酸催化剂。考察了氧烯比、水烯比、反应负荷等因素对催化剂性能的影响。

Based on the successful industrial application of the first generation acrylic acid catalyst,Lanzhou Petrochemical Research Center(LPCR) developed a second generation high-space-velocity and high-selectivity catalyst.In order to get the optimal process conditions,many reaction conditions,mainly including the oxygen-propylene ratio,water-propylene ratio,load capacity,were investigated in single-tube reactor.
