Abstract: As a renewable source of hydrocarbon fuel feedstock，non-edible oil has attracted world’s attention. With respect to low selectivity of decarboxylation as well as fewer saturated hydrocarbons and more oxygenated organics，the conventional method of cracking non-edible oil is not satisfactory. Microwave assisted cracking is better with high selectivivity，promotion of decarboxylation and high yield of hydrocarbon products. This paper reviews the commonly used methods of catalytic cracking，with emphasis on different catalysts and introduces microwave assisted cracking，which has a wide application prospect due to its low treatment cost and better product quality.

Key words: non-edible oil, cracking, catalyst, microwave

摘要： 非食用油脂作为一种生产可再生烃类燃料的原料，受到了全世界的关注。相对于常规的裂解非食用油脂生产烃类燃料的方法中存在的脱羧选择性较差、产物中饱和烃类少、含氧有机物多等问题，微波辅助裂解具有选择性、脱羧过程中微波具有促进作用、烃类得率高等优点。本文简述了目前常用的油脂催化裂解的方法，着重介绍了不同催化剂的催化裂解、微波辅助裂解制备液体燃料。通过比较，得出了微波催化裂解在燃料性能及处理成本上的优势，为制备低成本、高效能的可再生烃类燃料提供了新方法，具有广阔的应用前景。
