Abstract

The co-processing of fossil and waste raw materials can postpone the depletion of fossil resources. The effect of waste cooking oil addition to catalytic vacuum hydrocrack residue was studied. Commercial NiW/SiO –Al O , activated ben- 2 2 3 tonite, Fe O nanopowder, and synthesized CoMo/SiO , CoMo/Al O catalysts were used at 390 C and 15 MPa. The 2 3 2 2 3 products were analyzed by simulated distillation (SimDis), C, H, N, and S elemental analysis, GC and solubility in n- heptane. The vacuum residue conversion decreased in the order CoMo/Al O [ CoMo/SiO = NiW/SiO –Al O [ 2 3 2 2 2 3 bentonite = nano Fe O . CoMo/Al O catalyst was selected for hydrocracking the vacuum residue and its mixture with 2 3 2 3 waste cooking oil. The best yield of light compounds with the highest hydrogen content in the product occurred when 20 wt% of waste cooking oil and 80 wt% of vacuum residue were used. A bigger content of waste cooking oil generated an increase in the solid yield production (10 wt%). Co-processing produced lighter hydrocarbons and deoxygenation intermediates.
