陽離子交換樹脂催化油脂副產(chǎn)物制備生物柴油動(dòng)力學(xué)研究 摘要： 以棕櫚油脫臭餾出物（PODD）和無水甲醇為原料，強(qiáng)酸性陽離子交換樹脂為固體酸催化劑，在自制的固定床反應(yīng)器中進(jìn)行酯化反應(yīng)，成功合成了脂肪酸甲酯（生物柴油）。同時(shí)研究了該酯化反應(yīng)的動(dòng)力學(xué)。通過對(duì)實(shí)驗(yàn)結(jié)果的分析，發(fā)現(xiàn)此條件下脂肪酸甲酯的合成表現(xiàn)為二級(jí)不可逆反應(yīng)。根據(jù)動(dòng)力學(xué)數(shù)據(jù)，得到了實(shí)驗(yàn)條件范圍內(nèi)的反應(yīng)動(dòng)力學(xué)方程和參數(shù)，提供了利用油脂副產(chǎn)物制備生物柴油的最宜工藝條件。 Reaction Kinetics for Producing Biodiesel from By-products of Botanical Oils Catalyzed by the Cation Exchange Resin Abstract:Fatty acid methyl esters esters (biodiesel) were prepared by catalytic esterification from palm oil deodorizer distillate (PODD) and anhydrous methanol in self-made fixed bed reactor using cation exchange resin as solid acid catalyst. The reactional kinetics of the esterification is studied. The conclusion is obtained by analyzing the experiment result, finding that the synthetic reaction of Fatty acid methyl esters appeared to be a second- order irreversible reaction. According to the kinetic data of experiment, the kinetic equation and related parameters is obtained to the extent of the experimental conditions. The optimum conditions of Producing Biodiesel using by-products of botanical Oils are provided. |
