【摘要】 本文用脉冲色谱技术,在接近反应条件的高温下,研究了H型丝光沸石(HM)对甲苯的吸附性质,测得了不同焙烧温度的HM对甲苯的比保留体积和吸附热。说明焙烧温度未改变HM对甲苯的吸附能量和吸附表面积,而只改变了沸石单位面积上的吸附中心数目。并从实验结果看出,焙烧温度对HM的甲苯歧化活性的影响与比保留体积随焙烧温度的变化趋势颇为相似。更多还原

【Abstract】 Adsorption properties of toluene on the H-mordenite under the approximation condition of reaction have been studied by means of the pulse chromatog-raphic technique. The specific retention volume and adsorption heat of toluene on H-mordenite at various calcination temperatures were measured. It was found that the adsorption energy of H-mordenite for toluene and the adsorption surface area did not change with calcination temperature, but the number of adsorption sites per surface area were changed. The experimental results show that the effect of calcination temperature upon activity of disproportion-ation of toluene is similar to that upon retention volume on H-mordenite.更多还原
