摘　　要：利用微湿空气法对SiO2／γ-Al2O3催化剂进行处理,将其用于制取润滑油基础油。利用BET法对催化剂的结构进行测定,考察了微湿空气处理催化剂的最佳处理条件及活性组分的最佳负载量,在微型反应装置上应用该催化剂进行了α-烯烃聚合反应实验。结果表明,采用温度为170℃,压力为6．0 MPa,体积空速为0．5 h-1的最佳聚合工艺条件,微湿空气温度为45℃,处理温度为800℃,活性组分的质量分数为12％时,催化剂具有较好的催化活性和优良的经济性。润滑油的运动粘度为38．19 mm2／s,溴价为5．78 g(Br)／100 g,凝点为-43．0℃。The catalyst SiO2/γ- Al2O3 was treated by micro- wetness air for the production of lubricating base oil. The structure of the catalyst was determined by BET technology. The optimum treatment condition and the optimum content of active composition by micro- wetness air treating method were researched. The polymerization of α - olefin was performed on a microreactor with the catalyst The result shows that the catalyst is featured by high catalytic activity and advantage in economy when the best polymerization conditions with the reaction temperature at 170 ℃, reaction pressure at 6.0 MPa , the volume velocity at 0.5 h^-1, the micro wetness air temperature at 45 ℃, the reaction temperature at 800 ℃ and 12% mass fraction of active composition. The kinematic viscosity of lubricating base oil is 38.19 mm^2/S, bromine number is 5.78 g（Br）/100 g and pour point is 43.0 ℃.
