摘要：
Hydrocarbon in-situ reforming hydrogen supply technology based on solid oxide fuel cell (SOFC) is an important distributed and miniaturized hydrogen production solution. Traditional nickel-based reforming catalysts often face sulfur poisoning during the reaction with trace amount of sulfur in the feedstock. In some cases, the existing sulfur may even cause severe safety risks. In this paper, the mechanisms of sulfur poisoning are summarized; the compositions and contents of sulfur species in natural gas, liquefied petroleum gas and liquid hydrocarbon are briefly described; the reported sulfur resistant catalysts for different reforming reactions are reviewed, and the effective and feasible solutions for developing sulfur-tolerant catalysts are summarized. The mechanisms of sulfur poisoning could guide the design of sulfur-resistant reforming catalyst with high performance. Finally, the paper reveals that the improvement of catalytic overall performance, the pretreatment of reforming feedstock and the design of reforming reactor and other comprehensive anti-sulfur strategies are also important research directions. © 2020, Chemical Industry Press Co., Ltd.
