Abstract: Methane and carbon dioxide can be converted to syngas through dry reforming of methane. This reaction has attracted more and more attention because the two greenhouse gases CH4 and CO2 are utilized. The nickel-based catalysts have been studied extensively because of their high activity and low cost. In this review, several methods for preparation of nickel-based catalysts are briefly introduced. The sintering of nickel and carbon deposition are the two main problems of the nickel-based catalysts and the causes are discussed in detail. In addition, the approaches of anti-deactivation are introduced including using special support, adding auxiliary agent and constructing special structure. It is pointed out that how to solve the problems of catalyst sintering and carbon deposition is the focus of current research in this field.

Key words: dry reforming of methane, nickel-based catalysts, sintering, carbon deposition

摘要: 使用甲烷和二氧化碳为原料,通过甲烷干重整反应可以将其转化为合成气。由于此反应可以利用甲烷和二氧化碳这两种温室气体,因而近年来受到了研究人员广泛的关注。其中,反应所使用的Ni基催化剂由于其较高的活性和较低的成本得到了较为深入的研究。针对甲烷干重整Ni基催化剂,本文简要介绍了几种常用的制备方法,并指出了在反应条件下存在的活性组分Ni的烧结和积炭的生成这两个问题,还详细分析了其各自的影响因素。另外,还从使用特殊载体、添加助剂以及构造特殊结构三方面阐述了甲烷干重整Ni基催化剂的失活解决方案,并指出解决催化剂的烧结和积炭问题是当前该领域的研究重点。
