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%, C8-16hydrocarbons 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%, C8-16hydrocarbons 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.

Introduction: The utilization of biodiesel as an alternative fuel is turning out to be progressively famous these days because of worldwide energy deficiency. The enthusiasm for utilizing Jatropha as a non-edible oil feedstock is quickly developing. The performance of the base catalyzed methanolysis reaction could be improved by a continuous process through a microreactor in view of the high mass transfer coefficient of this technique. Materials & Methods: Nanozirconium tungstovanadate, which was synthetized using sol-gel preparation method, was utilized in a complementary step for biodiesel production process. The prepared material has an average diameter of 0.066 &µm. Results: First, the NaOH catalyzed methanolysis of Jatropha oil was investigated in a continuous microreactor, and the efficient mixing over different mixers and its impact on the biodiesel yield were studied under varied conditions. Second, the effect of adding the nanocatalyst as a second stage was investigated. Conclusion: The maximum percentage of produced methyl esters from Jatropha oil was 98.1% using a methanol/Jatropha oil molar ratio of 11 within 94 s using 1% NaOH at 60 &°C. The same maximum conversion ratio was recorded with the nanocatalyst via only 0.3% NaOH.

Maranhão state in Brazil presents a big potential for the cultivation of several oleaginous species, such as babassu, soybean, castor oil plant, etc... These vegetable oils can be transformed into biodiesel by the transesterification reaction in an alkaline medium, using methanol or ethanol. The biodiesel production from a blend of these alcohols is a way of adding the technical and economical advantages of methanol to the environmental advantages of ethanol. The optimized alcohol blend was observed to be a methanol/ethanol volume ratio of 80 % MeOH: 20 % EtOH. The ester content was of 98.70 %, a value higher than the target of the ANP, 96.5 % (m/m), and the biodiesel mass yield was of 95.32 %. This biodiesel fulfills the specifications of moisture, specific gravity, kinematic viscosity and percentages of free alcohols (methanol plus ethanol) and free glycerin.
