【摘要】 以一定浓度的酚醛树脂溶液对炭膜基板进行碳沉积处理，考察碳沉积条件对所制备的分子筛炭膜气体分离性能的影响。实验结果表明，较好的碳沉积条件为：碳沉积液浓度为６０％，浸渍时间为１２０ｍｉｎ，碳沉积次数为三次，热处理温度为７００℃。此膜对ＣＯ_２和Ｈ_２有很好的分离作用，两者的透过速率分别为１０^－６和１０^－５ｃｍ^３（ＳＴＰ）／ｃｍ^２·ｓ·ｃｍＨｇ数量级，分离系数可达１７．８。初步研究结果表明，此膜对ＣＯ_２／Ｏ２、ＣＯ_２／Ｎ_２和ＣＯ_２／ＣＨ_４也有一定的分离能力，分离系数在６．０左右。更多还原

【Abstract】 A certain concentration of PF solution served as carbon material was used to manufacture carbon molecular sieve membrane.The effect of carbon deposition condition on gas permeability and selectivity through the membrane was investigated.The results show that the optimum carbon deposition conditions are as follow:the concentration of the solution, 60%（Vol）; soaking time,120min, treatment number,3;heat-treatment temperature 700℃. The permeation rate of CO₂ and H₂ through the membrane is in 10￣（-6） and 10￣（-5） cm￣3 （STP）/cm￣2·s·cmHg order of magnitude respectively,the separation factor of H₂ to CO₂ is about 17.8.The preliminary results show that the membrane is effective for separating CO₂/O₂, CO₂/N₂ and CO₂/CH₄, the separation factor are about 6.0.更多还原
