Abstract:Pistacia oil is a kind of important biomass raw materials, the main fatty acids are oleic acid 51.17%, linoleic acid 28.76% and palmitic acid 17.75% by gas phase analysis. Fe/C-SO3H hollow fiber catalyst by spinning technology which homemade was hold for preparation of biodiesel. Through SEM and BET analysis, Fe/C-SO3H catalyst was hollow fiber structure, average around 1μm in diameter and specific surface area of 50.925 Am2.kg-1. It was concluded that the catalyst calcined at 400℃ and 2h in the nitrogen atmosphere to appropriate state by XRD characterization analysis. Catalysts is superparamagnetism fiber, was not aggregation in the condition of disappear the magnetic field by VSM analyze of characterization. Factors affecting the catalytic ester exchange reaction were optimized, it is concluded that 110 min in reaction time, catalyst dosage of 3.0% oil, mole ratio of alcohol oil 11:1, reaction temperature 75 ℃ to achieve the best condition for orthogonal design, the conversion rate is 97.2%. Pistacia oil and biodiese were analyzed by FT-IR, found consistent with theoretical analysis, and compared the biodiesel and 0# diesel, the experimental results show that the properties of biodiesel are excellent.
