以小桐子油为原料,开展固体碱催化小桐子油裂化制备生物基燃料油的研究,主要考察了反应温度、催化剂粒径和质量空速对生物基燃料油产率和产物成分的影响。结果表明:氧化钙催化小桐子油裂化制备烃类的最佳工艺条件为裂化温度为480℃、催化剂粒径为2～4mm和质量空速为2.4h-1,在此优化条件下液态烃类的产率可达70.75%,产物的酸值为0.9mg KOH/g,液态产物的主要成分是C5-C15的烯烃、烷烃和醇类,约占总产物的87.85%。可为油脂催化裂化制备生物基燃料油的深入研究提供依据。
Using jatropha curcas oil as raw material,bio-based fuel oil was prepared by solid base catalyzed cracking.The influences of reaction temperature,catalyst particle size and mass space velocity on the yield and product composition of the oil were studied.The results shown that the optimum technological conditions for preparation of hydrocarbon by solid base catalyzed cracking of Jatropha curcas oil were that reaction temperature 480℃,catalyst particle size 2～4mm and mass space velocity 2.4h-1.Under this optimal condition,the yield of liquid hydrocarbons can reach 70.75%,and the acid value of the products was 0.9mg KOH/g.The main component of the liquid product were C5-C15 olefins,alkanes and alcohols,which was account for about 87.85% of the total product.The results can provide a basis for the deep investigation on the preparation of bio-based fuel oil by catalytic cracking of oil.
