Research progress on biomass torrefaction pre-conditioning and optimization of pyrolysis product quality
摘要
Abstract
Biomass is green renewable energy with abundant reserves and is expected to replace fossil energy to reduce carbon emissions.However,its high oxygen content,high moisture content and high dispersion lead to a series of problems such as poor grinding performance and difficult storage and transportation,making it difficult to use as resources.The research progress on torrefaction pre-conditioning technology(hereinafter referred to as"torrefaction")to optimize the quality of biomass and its pyrolysis products at home and abroad was reviewed.It is emphasized that torrefaction can improve physicochemical properties of biomass and optimize the quality of pyrolysis products.The emission reduction and energy conservation effects of torrefaction were summarized.Torrefaction can improve the grinding energy,calorific value and activation energy of biomass,and help the energy characteristics of torrefied biomass to reach the level of fuel coal.The specific surface area of biochar after torrefaction combined pyrolysis increases,the pore structure becomes more complex,the contents of oxygen and acidic substance decrease,and the content of combustible components in pyrolysis gas increases,so the quality of products is improved.Suggestions were made for the development of this technology,and its potential applications were discussed.It is proposed that the torrefaction combined with pyrolysis technology can replace coal as one of the important thermal conversion technologies for preparing clean oil,carbon materials and syngas,and torrefaction biomass combined with thermal conversion and utilization of coal can improve the clean utilization level of coal,so as to realize the low-carbon reengineering of future industrial processes,and provide technical supports for China to achieve"carbon peaking and carbon neutrality"goals,revitalize rural areas and ensure energy security.关键词
