摘要
Abstract
The cordierite support was treated by soaking and heating it in the dilute nitric acid solution for different times, and the change rules of the specific surface area and pore structure with the treating time were found out, by which the support with definite specific surface area could be prepared. The treated supports were used to prepare the monolithic catalysts, and the reaction of CO coupling with methyl nitrite to dimethyl oxalate was carried out over the catalysts in a gradientless reactor. According to the conversion of methyl nitrite and the selectivity to dimethyl oxalate, the optimum support specific surface area was determined for this reaction.关键词
