Single-step Hydroconversion of Jatropha Oil to High Quality Fuel Oil over Reduced Nickel-Molybdenum Catalysts

摘要

The catalytic activities of reduced NiMo catalysts supported on Al2O3, SiO2-Al2O3, SAPO-11 and AlSBA-15 in hydroconversion of Jatropha oil were evaluated. A high deoxygenation ratio was achieved over each reduced catalyst as well as sulfided catalysts. Catalytic performance was obviously influenced by the acidity of supports, resulting in significantly different carbon number distribution in produced hydrocarbons. High yield of 74.6 % of C_(11)-C_(18) hydrocarbon products with low cloud point of ca. -16 °C was obtained in single-step hydrotreating of Jatropha oil over NiMo/SiO2-Al2O3 catalyst.
