甲烷二氧化碳催化重整制合成气的研究进展和工艺技术

Research Progress and Technology of Catalytic Reforming of Methane with Carbon Dioxide to Synthetic Gas

近几年随着我国科学技术和经济水平的不断发展和提升,随之而来的环境问题也日益严峻,而二氧化碳则是重要的一环,为此我国政府以及相关工作部门加强了对甲烷和二氧化碳催化重整制合成气的研究力度。在甲烷和二氧化碳催化重整的相关技术取得阶段成果的同时,在反应时涉及的难点部分:催化剂的活性组分、载体的研究以及助剂的研究取得了突破,这体现出对工业发展质量和速度的高度肯定,但重整过程中仍然存在催化剂积碳失活等问题。主要对重整过程进行了综述,对重整过程需要的催化剂活性组分、载体以及催化剂积碳行为进行了介绍,并对制备方法进行了讨论。

In recent years,with the continuous development and improvement of science,technology and economy in China,the environmental problems are becoming more and more serious.Carbon dioxide is an important link.Therefore,our government and relevant departments have strengthened the research on catalytic reforming of methane and carbon dioxide to syngas,in methane and carbon dioxide.At the same time,the related technologies of carbon dioxide catalytic reforming have achieved some achievements,and the difficult parts involved in the reaction:the research of active components,carriers and promoters of catalysts have made breakthroughs,which reflects the high affirmation of the quality and speed of industrial development,but the deactivation of catalyst carbon deposition still exists in the process of reforming.And so on.In this paper,the reforming process is reviewed.The active components,supports and carbon deposition behavior of catalysts needed in the reforming process are introduced.The preparation methods are also discussed.
