生物质水杂草热解基本规律研究 摘要 能源是人类生存与发展的前提和基础。生物质能是重要的可再生资源之一。从某种意义上讲，人类社会的发展离不开优质能源的出现和先进能源技术的使用。在当今世界，能源和环境，是全世界、全人类共同关心的问题，也是我国社会经济发展的重要问题。目前，燃料和化工利用的能源主要来源于石油、煤、天然气，但随着化石能源日趋严重的环境问题，开发新的能源已经迫在眉睫。 本文较详细介绍了国内外生物质热裂解研究现状，并在流动氮气气氛下，以水杂草为生物质原料，进行了加热条件下的裂解实验，着重考察了五种无机催化剂（KOH 、Na2CO3、、CaO、Mg(NO3)2、Fe2(SO4)3）对裂解气体产物分布的影响。通过气相色谱仪分析得出：裂解气体主要由H2、CH4、CO、CO2组成。 结果表明：催化剂对气体产物产生的时间有很大影响。强碱性催化剂（KOH 、Na2CO3）可以在很大程度提高了气体产率。而Fe2(SO4)3对气体的产生起到很大的阻碍作用，不同的催化剂催化效果不一样，有的催化剂促进液体生成，有的促进气体生成。 关键词：生物质，裂解，催化剂，气相色谱仪 STUDY ON THE PYROLYSIS LAWS OF BIOMASS-WATER WEED ABSTRACT Energy sources is the base of human survive and development. Biomass energy is one of the most important renewable energies. In a certain sense, the human societys development is inseparable from the emergence of high quality energy and advanced energy the use of technology. In todays world, energy and the environment, is the world, common humanity concern, China is the social economic development of important problem. At present, fuel and chemical use energy mainly comes from oil, coal, and natural gas, but with the fossil energy increasingly serious environmental problems, the development of new energy is imminent. In this study, state of art of biomass pyrolysis home and abroad was reviewed in detail and pyrolysis of water weed by heating was carried out under dynamic nitrogen flow. The experiments highlight the effects of the five inorganic katalyst（KOH 、Na2CO3、、CaO、Mg(NO3)2 、Fe2(SO4)3）on the pyrolysis temperature and distribution of gas products. It was found that gas product consists mainly of H2、CH4、CO、CO2 . The results show that the catalyst for gaseous product produce time has very big effect. A strong alkali catalyst (KOH, Na2CO3) can greatly improve the gas production rate and Fe2 (SO4)3 gas produced a big side effect, different catalytic effect is different, some catalyst promote liquid generation, some promote gas generation.
