Triglycerides Catalytic Hydroconversion into Bio-Aviation Fuels Based on Temperature by One-Step

Abstract:

One-step hydrotreatment of three different vegetable oils have been carried out over Pd loading bi-functional catalyst in batch reactor. Rubber seed oil, Jatropha oil and castor oil have different acid value and constituents, which will influence the hydroprocessing and the quality of products. With temperature rising, several principles have been summarized, and an optimal temperature corresponding to three oils have been determined respectively. At the optimal temperature of Jatropha oil, 300°C, deoxygenation rate was up to 99.29%, C_8-16 hydrocarbons of products was up to 77.36%; 310°C and 320°C were respectively optimal temperature of rubber seed oil and castor oil, deoxygenation rate were 99.15% and 98.78%, C_8-16 hydrocarbons were 71.46% and 69.25%. The products quality of Jatropha oil was better than rubber seed oil and castor oil, and rubber seed oil and castor oil can cause the deactivation of catalyst.
