摘要:

甲烷是氢碳比最高的烃,也是一种具有较高燃烧热值的清洁能源。在生物质制备甲烷的方法中,生物质发酵法和生物质合成气发酵法因活性菌的温度敏感性而受到限制。因此,本文介绍了近年来生物质合成气催化制备甲烷的反应机理及相应的催化剂体系研究进展,重点讨论了合成气中CO甲烷化和CO2甲烷化反应机理,以及催化剂中活性成分、载体、助剂对甲烷化的影响。同时,介绍了反应条件温和的生物质催化水热法,简述了反应路线及近年来的研究现状。最后,从技术的角度对该甲烷化的反应机理和高效、稳定的催化剂研究进行了展望。

关键词: 生物质, 甲烷, 催化水热法

Abstract:

Methane is the hydrocarbon with highest hydrogen-carbon ratio, and is a kind of clean energy with high combustion calorific value as well. During the preparation of methane from biomass, biomass fermentation and biomass syngas fermentation are limited by the temperature sensitivity of active bacteria. This paper introduces the research progress of reaction mechanism and corresponding catalyst system of biomass synthesis gas to methane by chemical catalysts. The reaction mechanism of CO methanation and CO2 methanation in syngas, as well as the effects of active ingredients, supports and promoters in catalysts on methanation are mainly discussed. At the same time, the catalytic hydrothermal method of biomass with mild reaction conditions is also introduced. The reaction route and research progress in recent years are briefly described. Finally, methanation reaction mechanism and efficient, stable catalysts are perspective remarked from the technical point of view.

Key words: biomass, methane, catalytic hydrothermal method
