Production and Analysis of Biodiesel from Non-Edible Seed Oil of Pistacia Chinensis

Abstract

Pistacia Chinensis is a potential and suitable non-edible feedstock for biodiesel production in China. In the present paper, three extraction methods to obtain seed oil of Pistacia Chinensis were compared and the Soxhlet extraction was found as the most effective one. Two kinds of biodiesels were produced catalyzed homogeneously by sodium hydroxide from crude oil of Pistacia Chinensis in Hebei province and Jiangsu province. Fourier transform infrared spectroscopy was used to compare the alterations of the functional groups in the crude oils and their biodiesel products after transesterification, and gas chromatography-mass spectrometry and gas chromatography were used to compare the composition of the biodiesels qualitatively and quantitatively. The results show that the C 18 fatty acid methyl esters are the main components in both the biodiesels, and the seed oil of Pistacia Chinensis from Hebei province is more suitable for biodiesel production than that from Jiangsu province in terms of their chemical structure.

Biodiesel production from non-edible plant oils

“…The term biofuel is as such referred to solid, liquid, or gaseous fuels that are produced from plant matter and residues, agricultural crops, municipal wastes, and agricultural and forestry by-products (Aburas and Demirbas, 2015a;Qin et al, 2009Qin et al, , 2010Altun and Yasar, 2013). Liquid biofuels can be used as an alternative to traditional fossil fuels in the transportation sector (Aburas, 2015).…”

Effect of compression ratio on the emission, performance and combustion characteristics of a gasoline engine fueled with iso-butanol/gasoline blends

“…Bio-fuels (methanol, ethanol, etc.) have been shown as good candidates as alternative fuels for vehicles because they are liquid, and have several physical and combustion properties similar to gasoline [2,3]. Alcohols have higher octane number and oxygen content.…”

Deacidification of Pistacia chinensis Oil as a Promising Non-Edible Feedstock for Biodiesel Production in China

“…The optimum reaction conditions were as follows: 6:1 molar ratio of methanol to oil, addition of 1.0 wt% catalyst, 60 min reaction time, and 60 °C reaction temperature. In a former study conducted by the researchers using the same experimental conditions [20], the average biodiesel yield from the seed oil of Pistacia chinensis plant from an identical location was only 67.5%. The reason for the lower biodiesel yield in that study was the corresponding lower quality of the oil.…”

“…There are few reports about using Pistacia chinensis as feedstock to produce biodiesel [19]. However, the high free fatty acid (FFA) content of Pistacia chinensis seed oil may be a major hindrance to the biodiesel production due to the use of dominant industrial basic catalysts [20]. It is well known that the higher FFA content of the feedstock greatly reduces biodiesel yield when using alkaline-catalysis technology.…”
