摘 要:研究了水蒸气处理对渣油加氢催化剂载体性质的影响。结果表明:处理时间、空速及焙烧温度对催化剂载体的孔结构和表面酸度均有显著影响;与在空气中焙烧相比,在有水蒸气存在的条件下恃烧,载体的相对酸度由1.000下降为0.491—0.884,相对比表面积由100下降为66~79,相对孔容由1.00上升为1.13~1.22,相对孔径由1.0上升为1.3~1.9。The influence of treating conditions in steam on the properties of residuum hydrocracking catalyst carrier was studied.The results showed that the pore structure and surface acidity of carrier were affected by treating time,space velocity and calcination temperature evidentially.Compared with air,on the conditions of steam during calcinations,the relative acidity of carrier decreased from 1.000 to 0.491~0.884,the relative specific surface decreased from 100 to 66~79,the relative pore volume increased from 1.00 to 1.13~1.22 and the relative aperture increased from 1.0 to 1.3~1.9.
