Abstract: Co-hydroprocessing of petroleum fractions with residual lipids is a promising technology for hybrid fuels production. The aim of this study is the identification of an effective operating window for co-hydroprocessing of Heavy Atmospheric Gas Oil (HAGO) with Waste Cooking Oil (WCO) within the nominal operating limits of a refinery. In particular, two Liquid Hourly Space Velocities or LHSVs (0.66 and 1 h −1 ) and three hydrogen-to-oil or H 2 /Oil ratios (300, 400 and 500 L H 2 /L feed) were studied for a HAGO/WCO 90/10 V/V blended feedstock over a commercial hydrotreating NiMo/Al 2 O 3 catalyst. The two parameters were evaluated with respect to the attained diesel content and quality of the produced hybrid fuels. All experiments were performed at a constant pressure of 5.6 MPa and temperature of 350 °C. The results have shown that higher LHSV is preferable in terms of the hydrogen consumption affecting the conversion cost. As far as H 2 /Oil is concerned, high H 2 /Oil ratios are more effective, rendering higher conversion, diesel content and heteroatom removal. [ABSTRACT FROM AUTHOR]
