Study on performances of glycerol to acrolein catalyzed by copper phosphates
摘要
Abstract
Converting glycerol into high-value-added acrolein is one of the effective ways to promote green and low-carbon development of chemical industry.The catalyst is the key factor influencing the production capacity of the glycerol to acrolein route.A series of copper phosphate catalysts were prepared by rotary evaporation method,and the catalysts were characterized by XRD,SEM and so on.Effects of different n(Cu)/n(P)and Cu sources on structure-activity relationships of catalysts were studied.The results show that increasing n(Cu)/n(P)can increase the specific surface area of catalyst,thereby improving the catalytic performance of the catalyst.Different Cu sources can affect the surface morphology of the catalyst,and thereby influence its acrolein selectivity.Under the conditions of reaction temperature of 300℃and glycerol solution(mass fraction of 10%)feed flow rate of 4 mL/h,the catalyst prepared with n(Cu)/n(P)of 1.0 and copper nitrate as the Cu source exhibits relatively optimal catalytic performance,with glycerol conversion rate,acrolein selectivity and acrolein yield of 97%,80%and 78%,respectively.关键词
