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.

Different technologies are currently available for biodiesel production from various kinds of lipid containing feedstock. Among them, the alkaline-catalyzed methods are the most widely studied. However, here are several disadvantages related to biodiesel production using alkaline catalysts such as generation of wastewater, catalyst deactivation, difficulty in the separation of biodiesel from catalyst and glycerin, etc. To limit the problems mentioned above, in this study, biodiesel is produced by a non-catalytic using C2H5OH. The effect of experimental variables (the molar ratio ethanol/oil of 41.18:1 – 46.82:1, reaction times of 50 - 90 minutes and reaction temperatures of 2750C - 2950C) on the yield of biodiesel was studied. The 96% yield of Cambodia biodiesel of reaction between C2H5OH and Jatropha Oil at 46:1 at temperature 2900C at 60 minutes no using catalysts. Obtained biodiesel fuel was up to the International Standard ASTM D6751 for biodiesel fuel blend stock (B100).

As petrol will soon be exhausted in the near future, Jatropha is going to be one of the substitute candidates for future biodiesel production. Countries of South-East Asia, such as Malaysia, they are going to start the establishment of Jatropha plantations assuming that Jatropha will be the main resource for biodiesel production. A press is commonly used to extract oils from Jatropha. An oil press can be manually driven or engine-powered. In this paper, we will review some available advances focused on mechanical extraction techniques, covering three types of press for Jatropha oil extraction. We have found that major points like operating principles, oil extraction levels, advantages and disadvantages of each press and important factors to increase oil recovery. Based on the study, three types of press are: ram press, which is ineffective; strainer press, which is able to produce more oil than others and cylinder-hole press, which is the best due to its capacity in extracting oil from Jatropha seeds for about 89.4% of oil yields.
