中文摘要:
      在生物柴油的制备方法中,目前最成熟、应用最多的是均相碱催化法,该方法反应所得到的粗酯需要经过一定的处理才能作为工业中应用的生物柴油.对粗酯的精炼方法,包括水洗蒸馏法、吸附法、反应分离耦合法、萃取反应耦合法等的研究与应用情况进行了分析评述,并指出各种方法存在的优缺点及未来的研究方向.
英文摘要:
      The most common method of biodiesel preparation is homogenous base-catalyzed reaction.The product of the reaction should be refined before using in industry.The methods of refining process,including washing-distillation method,absorbing method,reaction-separation coupling techniques and extraction-transesterification coupling method were discussed.The advantages and shortcomings of all the processes were carried out,and the directions of further research were indicated.
