摘要

以茶树[Camellia sinensis (L.) O. Kuntze]茶籽油为原料,研究了茶籽油甲酯化制备生物柴油的工艺条件。在单因素试验的基础上,选取反应温度、催化剂用量（占精炼油质量百分比）、反应时间和醇油摩尔比为影响因子,以酯交换率为响应值,应用Box-Behnken中心组合试验设计建立数学模型,进行响应面分析。结果表明,茶籽油制备生物柴油的最佳工艺条件为：反应温度58℃、催化剂用量1.05%、反应时间66min、醇油摩尔比9.7∶1。在此条件下,酯交换率达到98.73%。对生物柴油进行红外光谱和GC-MS分析,产品质量达到国家生物柴油标准。

Abstract

Methyl esterification preparation of biodiesel from tea seed oil was investigated. According to single factor investigation, a mathematical model with transesterification ratio as a response to reaction temperature, catalyst dosage, reaction time, mole ratio of methanol to oil was established using Box-Behnken central composite experimental design. This was followed by response surface analysis. It was found that the optimal process conditions for methyl esterification of tea seed oil were as follows: reaction temperature 58℃, catalyst dosage（mass percent to oil）1.05%, reaction time 66min, mole ratio of methanol to oil 9.7∶1, and that the resultant transesterification ratio was 98.79%. Fourier transforms infrared spectroscopy and GC/MS were used to analyze biodiesel, and the quality indexes of biodiesel in the experiment reached the national biodiesel standards of Chinese.

Key words： tea seed oil; methyl esterification; biodiesel; response surface
