以拟薄水铝石为铝源、水玻璃为硅源、十六烷基三甲基溴化铵为模板剂,在110℃水热条件下合成了含Al的MCM-41介孔分子筛。以AlMCM-41介孔分子筛为载体、以W和Ni为活性组分制备了加氢脱氮催化剂,在反应压力4 MPa、反应温度350℃、氢油体积比800及质量空速2.0 h-1条件下,喹啉的脱氮率可达99%以上。
The MCM-41 mesoporous molecular sieves containing Al were synthesized under the conditions of hydrothermal treatment at 110 ℃ with pseudoboehmite as aluminum source, water glass as silicon source and cetyltrimethylammonium bromide as templating agent. AlMCM-41 mesoporous molecular sieves were used as supports and W and Ni as active components to prepare hydrodenitrogenation catalysts. Under the conditions of reaction pressure of 4 MPa, reaction temperature of 350 ℃, volume ratio of hydrogen to oil of 800 and mass space velocity of 2.0 h-1 Conditions, quinoline denitrification rate of up to 99%.
