Abstract

Sustainable feedstock supply is the basis of biodiesel industry development.Consequently,it is very important to understand the characteristics and distribution of non-food biodiesel plant(NFBP) resources and the physicochemical property of the vegetable oil and their methyl esters(MEs) for the development of nonfood biodiesel feedstock production.Samples of thirty-seven plant species(seeds or kernels) which were plentifully distributed in Shaanxi province were collected and analyzed chemically.The result showed that the oil content varied between 10.0% and 62.8% and the iodine value,acid value,and saponification value of the exacted oil varied,respectively,between 43.43 and 129.44 g/100 g,between 1.89 and 57.92 mg/g,between 124.18 and 367.00 mg/g.Based on these tested data,5 parameters closely related to the fuel quality were calculated using regression models described in various literature.The results showed that the cetane number,kinematic viscosityof the vegetable oil MEs varied between 34.86 and 63.08,between 2.67 and 4.19 mm2/s;and the MEs density,high heating values,cold filter plugging point varied between 833.94 and 884.22 kg/m3,between 33.40 and 42.91 kJ/g,between-13.10 and 15.60 ℃,respectively.Ultimately,11 species were selected according to the preliminary evaluation standard of NFBP.The comprehensive evaluation of oil yield,adaptability and resistance ofthe screened 18 speciessuggested that the Prunusdavidiana Carr.,Magnolia of icinalis Rehd.et Wils and Ligustrumlucidum Ait could all be promising oil plants to bedeveloped in North China.
