【摘要】 以悬浮床加氢水溶性催化剂前体水溶液作为溶剂、以起泡剂作为溶质,制备胶质气体泡沫(CGA),并对其结构和稳定性进行了探讨;以辽河常压渣油和委内瑞拉常压渣油为原料油,对CGA分散水溶性催化剂的分散效果进行了光学显微镜观察,并评价了其悬浮床加氢反应的性能。结果表明,与催化剂前体水溶液直接分散相比,CGA分散的辽河常压渣油悬浮床加氢的生焦率由2.33%降至1.67%,委内瑞拉常压渣油的生焦率由2.74%降至2.05%;馏分油收率有所提高。更多还原

【Abstract】 The solution of catalyst precursor for slurry phase hydro-processing and a foaming agent were used as solvent and solute,respectively,to prepare colloidal gas aphron(CGA).The structure and stability of CGA were discussed.Liaohe and Venezuela atmospheric residual oil(LHAR and VRAR) were taken as base oil to study the dispersion effect of CGA.The microscope observation and autoclave reaction were used to evaluate the dispersion effectiveness of CGA catalyst.The results showed that compared to the catalyst precursor as aqueous solution dispersed directly in oil,the coke yields of LHAR and VRAR slurry-bed hydro-processing catalyzed by the catalyst in the form of CGA reduced from 2.33% to 1.67% and from 2.74% to 2.05%,respectively,with the increase of distillate yield to some extent.更多还原
