Abstract

Fortynine wild oil plants which are abundant in the Tsinling and Zhongtiao Mountains were investigated and screened as raw material for biodiesel production The oil content was tested and found to be greatly variable ranging from 10 to 628  Fatty acid profiles of their vegetable oils were analyzed and their acid value saponification number and iodine value were found to range from 16 to 613 mg KOH/g 1286 to 2259 mg KOH/g and 543 to 1209 g I2/100 g respectively Cetane number kinematic viscosity specific gravity high heating values and cold filter plugging point of the 49 vegetableoil methyl esters MEs were empirically calculated and were found to vary from 388 to 666 29 to 42 mm2/s 8414 to 8838 kg/m3 390 to 475 kJ/g and −143 to 132 °C respectively Almost half 25 species of all the sampled resources were found to be suitable for biodiesel production since the profiles of their vegetableoil MEs met the major specifications of Chinese and European Union biodiesel standards GB/T20828 and EN14214 respectively Grey relational analysis was used during the optimumspecies screening process The difference between the individual species and the artificial designed ideal species the best biodiesel plant type in this paper was calculated and evaluated with the help of grey relational grade which varied from 0467 to 0686 Finally the selected plants Prunus salicina Linn and Amygdalus davidiana C C de Vos were considered as the optimal feedstock for biodiesel production
