Studies On Catalysts And Hydroprocessing Technology For Production Of Bio-diesel

Renewable liquid alkanes can be produced by hydrotreating of vegetable oils and animal fats at standard hydrotreating conditions with conventional hydrotreating catalysts.In this paper, Hydrogenation of vegetable oils and animal fats on CoMo/γ-Al2O3, NiMoP/γ-Al2O3 and NiMoP/USY+γ-Al2O3 catalysts was separately investigated in a high pressure fixed bed micro-reactor. For hydrogenation of vegetable oils and animal fats under conditions of pressure 3.0 MPa, temperature 320℃, LHSV 2.0 h-1 and volume ratio of H2 to oil 500 on CoMo/γ-Al2O3 and NiMoP/γ-Al2O3 catalysts separately, the main product was n-C15-18, but on NiMoP/γ-Al2O3-HUSY catalyst containing acidic component with higher cracking ability, main product of hydrogenation was
