摘要： The present invention relates to an improved, fully-integrated continuous process of enhanced process operability for manufacturing copolyether glycols having enhanced physical properties by polymerization of a reaction mixture comprising tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst and at least one compound containing reactive hydrogen atoms. The copolyether glycols manufactured by the present process have enhanced physical properties of increased alkylene oxide incorporation, average molecular weight and polydispersity, as well as reduced crystallinity, color, oligomeric cyclic ether content, and linear oligomer having an average molecular weight of up to about 400 dalton content.

摘要： A method for preventing pressure build-up across a catalyst separation in a polyether polyol reactor comprising the steps of feeding reactants that comprise a monomer or co-monomers to be polymerized to form the polyether polyol into a continuous feed reactor, flowing the product stream through a catalyst separation system within the reactor, wherein the catalyst separation system is comprised of a plurality of filters, wherein each filter comprises an outer surface and an inner surface defined by a plurality of spaced-apart elements, and wherein the distance between the spaced-apart elements is smaller than the minor dimension of the suspended catalyst and recovering the filtered polyether polyol product and catalyst fines from the reactor outlet.

摘要： An improved process for selective vapor phase oxidation of n-butane to maleic anhydride involving the use of a recirculating solids reactor having a reaction zone and a catalyst regeneration zone wherein n-butane is converted to maleic acid in the reaction zone by use of a vanadium/phosphorous oxide (V/P/O) catalyst in oxidized form and the reduced vanadium/phosphorous oxide catalyst is regenerated by contact with oxygen in the regeneration zone. Replenishment of the inherent catalyst losses associated with the catalyst recycling process is accomplished by adding to the catalyst in the regeneration zone vanadium/phosphorous oxide catalyst precursor at a rate of addition that effectuates in situ calcination and activation of the vanadium/phosphorous oxide catalyst precursor while simultaneously maintaining the desired operating temperature of the n-butane to maleic anhydride conversion reaction. Such a process is useful in maintaining the high operating capacity of the reactor over an extended period of time.
摘要翻译：涉及使用具有反应区和催化剂再生区的再循环固体反应器的正丁烷选择性气相氧化为马来酸酐的改进方法，其中正丁烷通过使用钒转化为反应区中的马来酸氧化形式的氧化亚铜（V / P / O）催化剂和还原的钒/磷氧化物催化剂通过与再生区中的氧接触而再生。与催化剂再循环过程相关的固有催化剂损失的补充通过在再生区钒/磷氧化物催化剂前体中以催化剂加入的速率加入催化剂来实现，该速率实现了钒/氧化磷催化剂前体的原位煅烧和活化，同时保持正丁烷所需的操作温度至马来酸酐转化反应。这种方法对于在长时间内维持反应堆的高操作能力是有用的。
