Abstract


Biodiesel is a renewable biomass energy, bio-diesel can not only reduce human dependence on fossil energy, but also reduce environmental pollution. Thesis, we selected the pistache seed as a biodiesel feedstock, transesterification of the the Pistacia chinensis seed oil into bio diesel, grease extraction method comparison studies, Experimental preparation of biodiesel, biodiesel determination of physical and chemical indicators. Specific conclusions are as follows: paper, crushing and extraction are two ways to extract from the Pistacia chinensis seed the pistache seed oil, and compare the two extraction methods on the of Pistacia chinensis seed oil extraction rate, physical and chemical characteristics and fatty acid composition of ingredients. The results show that: the two methods obtained Pistacia chinensis seed oil fatty acid composition and physical and chemical indicators are similar, but significantly higher mechanical compression of the Pistacia chinensis seed oil acid value, and the low quality of the grease. Therefore, the extraction method is more suitable for the extraction of Pistacia chinensis seed oil. Papers for the determination of of Pistacia chinensis seed oil physical and chemical properties in accordance with the national standards and fatty acids, the results showed that: Pistacia chinensis seed containing 46.38% oleic acid, linoleic acid 32.24%. Therefore, pistache is a species of the prospects for the development of new oil crude material. Paper, ultrasound-assisted preparation of biodiesel, in the role of a catalyst and of Pistacia chinensis seed oil and methanol transesterification biodiesel process was studied. The results showed that the optimum conditions: ultrasonic power 40W constant, ultrasonic time 65min, the amount of catalyst was 0.8%, the oil alcohol molar ratio of 1:6, under this condition the biodiesel reaction conversion rate as high as 93.56%. The papers using gas chromatograph for preparing biodiesel chromatographic analysis, The results showed that: methyl oleate content of linoleic acid methyl ester, 41.77%, 30.43%, methyl palmitate 11.82%, 1.81% methyl hemp and stearic acid methyl ester was 1.17%. That the fatty acid methyl esters in biodiesel reached more than 90%. In addition, ultrasound-assisted and traditional water bath heating method on the preparation of biodiesel compared results of the ultrasonic assisted preparation of biodiesel short reaction time, catalyst with less energy consumption. Biodiesel is the new field of energy research and development at home and abroad in recent years, one of the hotspots of the application, an important factor in limiting its industrial development problem of raw materials. Paper work done on the one hand Pistacia chinensis seed oil biodiesel to provide a scientific basis, it also opened up new avenues for of pistache resources in Anhui Province development and comprehensive utilization, with strong theoretical and practical significance.
