摘要:

天然气储量丰富,是优质的清洁能源,甲烷作为其主要成分,通常经由重整工艺来制备。而重整过程中由积炭烧结等引起的催化剂失活问题是阻碍该工艺大规模工业化发展的关键因素。基于铁基催化剂,从催化剂活性组分、载体、助剂以及制备方法等角度综述了甲烷裂解重整催化剂性能的研究进展。基于Ni-Fe双金属催化剂综述了甲烷蒸汽重整及二氧化碳重整催化剂性能的研究进展。阐述了催化剂的失活原因以及提高重整催化剂性能的方法。为了促进重整工艺的工业应用,未来应深度探讨铁基催化剂的积炭机理,选取合适的载体及助剂来优化铁基催化剂的性能。

Abstract:

Natural gas is abundant, and methane is the main ingredient, which is usually used through reforming to produce high-quality clean energy. However, the catalyst deactivation caused by carbon deposition and sintering in the reforming process is a key factor hindering the large-scale industrial development of this process. Based on iron-based catalysts, the research progress on the performance of methane cracking reforming catalysts was reviewed from the perspectives of catalyst active components, supports, additives and preparation methods. Based on Ni-Fe bimetallic catalysts, the research progress on the performance of methane steam reforming and carbon dioxide reforming catalysts was reviewed. The causes of catalyst deactivation and the methods to improve the performance of reforming catalysts are described. In order to promote the industrial application of the reforming process, the carbon deposition mechanism of iron-based catalysts should be deeply explored in the future, and appropriate carriers and additives should be selected to optimize the performance of iron-based catalysts.

Key words: methane reforming, catalyst, iron-based catalysis, activity, deactivation
