本文提出在高于室温的条件下用气相法测定吸附平衡数据.测定了对二甲苯、间二甲苯、邻二甲苯和乙苯四个纯组分在175℃下的饱和吸附量(用法测得的KY分子筛微孔体积与晶格理论计算的微孔体积是一致的)。测定了碳八芳烃异构体组成的六种二元溶液于90℃和475℃下在KY分子筛上的吸附平衡数据。并推出适用温度范围从30℃到175℃,包含温度变量的全浓度范围的普遍化吸附平衡关系。用普遍化吸附平衡关系计算了30℃、90℃和175℃三个温度下全浓度范围的吸附平衡数据。所得计算值与实验值的相对误差(除个别点外)均在5％以内。
In this paper, the adsorption equilibrium data were determined by gas-phase method above room temperature.The saturated adsorption capacity of four pure components of p-xylene, m-xylene, o-xylene and ethylbenzene at 175 ℃ Of the KY molecular sieve pore volume and lattice theory calculated micropore volume is consistent). The adsorption equilibrium data of six binary solutions composed of carbon isocyanide isomers on KY zeolites at 90 ℃ and 475 ℃ were measured. And generalized adsorption equilibriums for the full range of concentrations, including temperature variability, are available for use in the temperature range from 30 ° C to 175 ° C. The adsorption equilibrium data of the full range of concentration at three temperatures of 30 ℃, 90 ℃ and 175 ℃ were calculated by generalized adsorption equilibrium. The relative error between the calculated value and the experimental value (except for some points) is within 5%.
