【摘要】：以獲得高酸值麻瘋樹油的生物柴油工業(yè)生產(chǎn)基礎(chǔ)技術(shù)參數(shù)為目的,研究了高酸值麻瘋樹油的酸堿兩步法催化制備生物柴油工藝。結(jié)果表明:在65℃、催化劑濃硫酸用量1%、反應(yīng)120 min、醇油摩爾比9∶1的條件下,高酸值麻瘋樹油經(jīng)預酯化處理其酸值從14.85 mg KOH·g-1降至0.41 mg KOH·g-1,滿足堿催化的原油酸值要求;Na OH催化酯交換的優(yōu)化工藝條件為:反應(yīng)30 min、反應(yīng)65℃、催化劑用量1%、醇油摩爾比6∶1,在此優(yōu)化條件下,酯交換率達到90.55%。制備的生物柴油中脂肪酸甲酯含量占總組分的98.73%,主要理化性能符合生物柴油標準。
[Abstract]:In order to obtain the basic technical parameters of biodiesel production of jatropha curcas oil with high acid value, the preparation process of biodiesel from jatropha curcas oil with high acid value by acid-base two-step method was studied. The catalyst concentration of sulfuric acid is 1: 1, the reaction time is 120 min, the molar ratio of alcohol to oil is 9: 1, The acid value of high acid value jatropha curcas oil was reduced from 14.85 mg KOH 路g -1 to 0.41 mg KOH 路g -1 after pre-esterification. The optimum conditions for transesterification of alkali-catalyzed crude oil were as follows: reaction time 30 min, reaction temperature 65 鈩，
