Abstract:

Cellulose is an important component of biomass, and pyrolysis technology is a high-value conversion technology with promising application prospects. It is of great significance to use cellulose pyrolysis to produce various fuels and high-value chemicals for the development of chemical industry. The study on cellulose pyrolysis mechanism and model is helpful to control the cellulose pyrolysis process and distribution of pyrolysis products. Therefore, based on the cellulose pyrolysis mechanism and kinetic model, the applications of pyrolysis products (pyrolytic gas, pyrolytic carbon, pyrolytic oil) in the process of cellulose pyrolysis are summarized, especially the selective production of high-value chemicals produced based on pyrolysis oil. The effects of different catalysts on the preparation of levoglucosenone (LGO), 1-hydroxy-3,6-dioxabicyclo [3.2.1] oct-2-one (LAC), furfural, aromatics and phenols were analysed, and the optimal conditions for the preparation of these value-added chemicals from catalytic pyrolysis of cellulose were investigated. Finally, the problems in the preparation of high-value chemicals from cellulose pyrolysis were pointed out, and the future of the research was prospected.
