摘　　要：为了获得可用于催化裂化干气中吸附分离丙烯用的活性炭,选择国内有代表性的不同材质和产地的活性炭,测定了比表面积、孔容、平均孔径和微孔体积等物性参数。在自制的吸附实验装置上,测定了101.3kPa、40℃下丙烯和乙烯在不同活性炭上的吸附量,比较对丙烯的选择性。结果表明在上述吸附条件下,活性炭AC-1对丙烯的吸附量最大,达3.552mmol/g,对丙烯的选择性为1.37。测定了乙烯丙烯二元混合气中,不同丙烯分压下,活性炭AC-1对丙烯和乙烯的吸附量。活性炭AC-1适用于干气吸附分离丙烯过程。Characteristics of activated carbon adsorbents for the separation of propylene from dry gas are studied.Five kinds of activated carbon of different material are selected as candidates.Physical parameters such as BET surface area,pore volume,average pore diameter and micropore volume are measured.The adsorption amounts of activated carbons for ethylene and propylene,as well as the selectivities for propylene are obtained at a condition of 101.3 kPa and 40℃.Under above conditions the adsorption amount of activated carbon AC-1 for propylene can reach 3.552 mmol/g,which is the largest among all prepared catalysts.The adsorption amounts for propylene and ethylene are also measured under a range of partial pressure in binary mixed gas of ethylene and propylene.As a result AC-1 is chosen as the optimal one for the separation of propylene from dry gas.
