生物质热解炭化的关键影响因素分析

Analysis on influence factors of biomass pyrolysis carbonization

随着能源消耗需求的增加,气候变化对环境的不利影响等问题的出现,生物质热解炭化技术作为发展可再生能源的重要措施,得到世界范围内越来越多的关注。文章综合分析了生物质原料(种类、粒径、全水分)、热解反应参数(热解温度、升温速率、热解压力、反应气氛、反应时间)以及催化剂等因素对热解炭化过程及产物生物炭的影响,认为目前的热解炭化技术在合理选择工艺参数、能源消耗等方面的研究还不够深入,并提出了相关建议,以期为热解炭化技术的产业化发展提供思路。

As the increase of energy consumption demand and adverse effects of climate change on the environment,etc, the biomass pyrolysis carbonization technology as an important measure for the development of renewable energy has got more and more attention in the worldwide. This article provides comprehensive analysis on the biomass raw materials （type, particle size, total moisture）, pyrolysis reaction parameters （pyrolysis temperature, heating rate, pyrolysis pressure, reaction atmosphere, reaction time） and the influence of catalyst on the pyrolysis carbonization process and biological carbon product. It was found that the current pyrolysis carbonization technology does not go far enough on the rational choice of process parameters and energy consumption. And some suggestions was provided for the development of pyrolysis carbonization technology industrialization.
