中文摘要：
油品资源短缺及其衍生的环境污染问题使得可再生清洁的生物柴油备受关注.生物柴油的生产技术途径多种、原料品种多样、生产过程副产物的利用方式多变,导致对其生产过程的客观全面评价较困难,至今仍缺乏这方面的系统性研究.试验以层次分析法为基础,建立了综合评价模型,分析不同生产工艺的技术适用性、经济可行性及其对环境的影响.结果表明：环境影响与原料供给在评价体系中所占权重最大,固体酸催化酯交换法综合得分最高,为70.41.研究结果为生物柴油产业的工艺优化与技术升级提供了指导方向.
英文摘要：
Considerable attention has been given to biodiesel towards diminishing fossil fuel reserves and associated environmental problems from burning.Biodiesel is the most attractive alternative fuel because of its good combustion properties and renewable features.There are a number of choices with regard to biodiesel production technology,raw materials and byproduct utilization patterns,making difficult to evaluate its production process comprehensively.A comprehensive evaluation model,based on AHP,taking technology applicability,economic feasibility and environmental impact into consideration,was established.The weights of environmental pollution and feedstock supply were the greatest,and heterogeneous acid-catalyzed transesterification seemed most promising.
