摘要: The process of co-hydrotreatment straight-run diesel fraction (DF) and vegetable oil (VO) on Co(Ni)-PMo/Al2O3 catalysts prepared from H3PMo12O40 cobalt (nickel) citrate has been studied. It shown that under conditions close to those in the industry, complete conversion fatty acid triglycerides (FATG) is achieved both types give an ultraclean hydrotreating product a 97% yield cetane number 5 points above DF alone. degree hydrodesulfurization (HDS) reduced more significantly Co-PMo/Al2O3 catalyst than case Ni-PMo/Al2O3. are susceptible deactivation blended feedstock containing VO. sample less stable Examination spent by transmission electron microscopy average particle length active phase increases, whereas this increment for Ni-PMo/Al2O3 insignificant, indicating higher stability particles NiMoS phase. Thus, co-hydrotreating petroleum fractions reasonable carry out NiMo/Al2O3 catalysts.
