摘要
Abstract
1,3-propanediol was synthesized without generating aldehyde by-products by catalytic hydrogenation of diethyl malonate over Cu/HMS catalyst in a continuous high pressure fixed-bed reactor.Effects of raw material concentration,ratio of H2/DEM,liquid hourly space velocity,reaction temperature and reaction pressure on the hydrogenation reaction were investigated. And the main causes of the catalyst deactivation were analyzed by XRD and TEM characterizations.Under the condition of raw material concentration as 7.5wt%,ratio of H2/DEM as 400,liquid hourly space velocity as 1.8h-1,reaction temperature as 200℃ and reaction pressure as 1.8MPa,the catalyst showed good catalytic hydrogenation performance,and diethyl malonate conversion and 1,3-propanediol yield reached 93.4% and 52.8%,respectively.The catalyst was deactivated completely after 120h.From both XRD and TEM results,the main causes for the catalyst deactivation were considered as the agglomeration of particles,loss of active components or the partial oxidation to Cu+.关键词
