摘要
结合微波辅助热解技术简述了微波加热原理及特性,讨论了废油脂原料特性及微波吸收剂等对产物分布及组成的影响,介绍了废油脂热解中常用的分子筛催化剂和金属氧化物催化剂,论述了微波驱动型催化剂的制备工艺和微波串联体系的搭建及其在废油脂微波热解中的应用研究,并总结了微波加热和电加热在催化体系的应用效果对比。最后,针对微波辅助/催化热解废油脂制备富烃生物油技术面临的挑战及未来研究方向提出了建议,为解决废油脂热解过程中催化剂易结焦失活、产物复杂等难题提供了新思路。
Combined with the the microwave-assisted pyrolysis technology,microwave heating principle and characteristics were briefly described,and the effects of the characteristics of raw material waste oil and microwave absorbers on the product distribution and composition were discussed.Zeolite catalyst and metal oxide catalysts used in waste oil pyrolysis were introduced.The preparation process of microwave driven catalyst and the establishment of microwave tandem system and its application in microwave pyrolysis of waste oil were reviewed.The application of microwave heating and electrical heating in catalytic system were also discussed.The challenges and future research direction of microwave-assisted fast pyrolysis of waste oil for hydrocarbon-rich bio-oil were put forward,which provided a new idea for solving the problems such as the coking and deactivation of catalysts and the complex composition of bio-oil in the process of waste oil pyrolysis.
