Abstract
With the growth of global energy demand and the intensification of environmental problems, biomass energy as a renewable energy, its conversion technology research and application has been widely concerned. In the introduction part, the paper first introduced the research background and significance of biomass energy conversion, summarized the research status at home and abroad, and clarified the purpose of the research, that is, optimize the biomass energy conversion process through chemical engineering means, improve the conversion efficiency and economy. In chapter 2, the chemical composition and physical characteristics of biomass energy and the pretreatment technology of biomass are described in detail. These basic knowledge provide the necessary prerequisite for understanding the biomass energy conversion process. In chapter 3 and Chapter 4, the thermochemical and biochemical transformation processes are discussed respectively. Thermochemical transformation processes include combustion, gasification, catalytic cracking and biomass liquefaction, while biochemical transformation processes cover enzymatic hydrolysis, fermentation, microbial transformation and photobiological transformation. In these two chapters, the principles, advantages and limitations of various conversion processes are analyzed in depth, and the chemical reaction mechanism in the conversion process is discussed. Chapter 5 focuses on process optimization strategies, including raw material supply and management, process parameter optimization, economic analysis, and risk management and countermeasures. These strategies aim to improve the efficiency and economics of biomass energy conversion while reducing environmental and social risks. Chapter 6 demonstrates the effects and challenges of process optimization in practical biomass conversion projects through case studies and practical applications, and evaluates the environmental and social impacts. Finally, Chapter 7 prospected the future research direction, including the development of new biomass resources, the innovation of efficient conversion technology, the exploration of system integration and polygeneration technology. These research directions will help promote the progress of biomass energy conversion technology and the development of the industry.
