Research progress in the preparation of high value added chemicals by directional pyrolysis of biomass
The production of petroleum-based chemical products,which are used in various daily and industrial goods such as cosmetics,lubricants,plastic products,and synthetic fibers,has led to a heavy dependence on petroleum as a raw material.As a result,there has been widespread attention on the production of high-value platform chemicals using renewable biomass as feedstock.Biomass pyroly-sis offers a selective approach to produce a variety of high-value platform chemicals,and it has become a frontier and hotspot in global research.This article provides a systematic overview of the production of commonly used high-value chemicals through biomass pyrolysis.Firstly,it summarizes the effects of pyrolysis feedstock,pyrolysis techniques,pretreatment methods,reaction temperature,reaction time,and catalysts on the production of target high-value products.Secondly,it analyzes the reaction path-ways for the production of target products through biomass pyrolysis.Finally,the future development di-rections for the production of platform chemicals through biomass direct thermochemical conversion are explored,providing a basis and reference for the efficient conversion and utilization of biomass.
