秸秆能源化利用技术综述

摘要

秸秆能源化利用技术是近年来迅速发展起来的生物质能利用新技术，我国农作物秸秆资源丰富，秸秆生物质资源的有效利用对解决环境污染和优化能源结构具有重要的意义。综述了秸秆固化、秸秆沼气、秸秆气化、秸秆发电、秸秆液化等秸秆能源化利用技术的原理，分析了各类技术的发展状况及存在的问题，认为在部分技术中存在生产成本高、技术不成熟、生产效率低、能耗高、行业标准缺失等问题，最后展望了秸秆能源化利用技术的发展方向和未来发展趋势。%The energy-from-straw utilization technology is a new biomass energy utilization technology which is rapidly de -veloped in recent years .There are rich crop straw resources in China , and the effective use of straw biomass resources has important significance for the solution of environmental pollution problem and the optimization of energy structure .The article summarizes the principle of energy-from-straw utilization technologies (straw curing, straw biogas, straw gasification, straw power-generation, straw liquefaction , etc.) , and analyzes the developmental status and existing problems of various technologies .We think that some technologies have the following problems:high cost of production , immature technology , low productivity , high energy consumption , and lack of industrial standards .Finally the author discusses the developmental direction and future trend of straw energy utilization technology .
