摘要
Abstract
Macroporous α-Al2O3 supports were prepared by using the γ-Al2O3 as raw material, washing it with dilute nitric acid, impregnating the washed γ-Al2O3 with NH4F and then calcining it in the muffle furnace. The samples were characterized by DTG, XRD, SEM and mercury intrusion method. Results show that the sample calcinated under 1050℃ had high purity of α-Al2O3 crystal, high crystallinity, uniform pore size distribution with a average pore size of 2066nm. Furthermore, the α-Al2O3 supported Pd catalyst was prepared and used for CO coupling to produce dimethyl oxalate, over which the conversion of CO could reach 89.0% with a se-lectivity to dimethyl oxalate of 97.6%.关键词
