生物质反应热力学气化模型的建立 Study on Thermodynamics Model of Biomass Gasification 摘要 生物质热气化过程的模拟计算可以比试验更方便、更快速认知地生物质热转化特性，对发展生物质热转化技术和实现生物质能源的高效利用具有十分重要的意义。本文阐述了生物质和生物质能的概述、国内外生物质模拟技术发展状况、国内外对生物质的应用现状、生物质气化主要反应，并对我国的研究背景及现状进行分析，以及对未来发展的展望。研究了松木屑、秸秆、稻壳、棉柴在气化炉中不同温度条件下的空气气化特性，并采用MABLAB对气化过程进行了模拟计算。最后通过对MABLAB软件计算所得数据与进行实验所得数据进行比较、分析。验证模拟技术进行数据分析的可行性。 关键词 生物质气化，模拟技术，反应平衡常数K Abstract Simulation Calculation of the transformation process of the biomass pyrolysis can be more convinent and more quickly to cognitive the characteristics of the biomass pyrolysis than test , and it has a very important significance in developing the technology of Simulation Calculation of the transformation process and achieve the efficiently use of the biomass energy . This paper describes the overview of biomass and biomass energy , the development of biomass simulation technology at home and abroad , the application of biomass at home and abroad , the main reaction of biomass gasification , and analysy the background and current situation of the research of China , we also make the outlook of the future development . We also study the characteristics of air gasification of Pine sawdust, straw, rice husk, cotton Cai in different condition of temperature in the gasifier , and make the simulation for gasification process using MABLAB. Finally we make comparison between the calculated data using MABLAB software and the calculated data from experiment ,and analysis to verify that if it is feasible for simulation technology to make data analysis .
