季铵盐型改性淀粉辅助蒸汽相法合成多级孔 EU －1沸石及其催化性能
Synthesis of hierarchical EU - 1 zeolite using quaternary ammonium salt modified starch assisted vapor phase method and its catalytic performance
摘要
Abstract
Using quaternary ammonium salt modified starch as mesoporous template,hierarchical EU - 1 zeolite was synthesized by vapor phase method. The physicochemical properties of the synthesized samples were characterized by XRD,FT - IR,SEM,N 2 adsorption - desorption and NH3 - TPD. The results showed that by regulating the dosage of quaternary ammonium salt modified starch,the mesoporous pore volume of the sample is increased by 0. 081 cm3 / g and the apparent surface area of the sample is increased by 23. 35 cm2 / g. The catalytic performance of the samples is examined by xylene isomerization test. The results showed that the equilibrium concentration of PX is increased by 0. 88 percent points,the ethylbenzene conversion is increased by 8. 47 percent points and the yield of C8 hydrocarbons is increased by 1. 66 percent points.关键词
