化石燃料脱碳是一种显著减少大气中二氧化碳排放的新兴技术方法。本文讨论了甲烷(天然气)热催化裂解制氢作为一种可行的脱碳策略。该技术方法的基础是甲烷和其他碳氢化合物在无空气/水的环境中在碳基催化剂上一步分解(热解)。这种方法消除了传统工艺(例如甲烷蒸汽重整)所需的水-气变换和二氧化碳去除阶段，大大简化了工艺。清洁碳是这一过程的一种有价值的副产品。给出了不同碳基催化剂在甲烷裂解反应中催化活性的实验数据。文中还讨论了适用于甲烷裂解产生富氢气体和连续提取元素碳的反应器的各种概念设计。(C)2001年国际氢能协会。爱思唯尔科学有限公司出版。版权所有。
Fossil fuel decarbonization is an emerging technological approach for significant reduction Of CO2 emissions into the atmosphere. CO2-free production of hydrogen via thermocatalytic decomposition of methane (natural gas) as a viable decarbonization strategy is discussed in this paper. The technical approach is based on a single-step decomposition (pyrolysis) of methane and other hydrocarbons over carbon-based catalysts in an air/water free environment. This approach eliminates the need for water-gas shift and CO2 removal stages, required by conventional processes (e.g. methane steam reforming), which significantly simplifies the process. Clean carbon is produced as a valuable byproduct of the process. The experimental data on the catalytic activity of different carbon-based catalysts in methane decomposition reaction are presented in this work. The paper also discusses various conceptual designs for the reactor suitable for decomposition of methane with production of hydrogen-rich gas and continuous withdrawal of elemental carbon.
