Abstract:

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.

Key words: microwave-assisted pyrolysis, waste oil, catalysis, hydrocarbon-rich bio-oil, renewable energy
