摘要
阐述了吸收强化甲烷水蒸气重整制氢(SESMR)反应机理及其影响因素,重点从活性中心Ni,助剂(铝、镧、锆、镁、钴)掺杂和构型调整方面综述了 SESMR工艺中Ni基复合催化材料的研究进展,还介绍了 SESMR复合催化剂在应用中的再生、以及其他复合催化剂的研发情况.并指出:易积炭和高温烧结是Ni/CaO复合催化剂大规模应用于SESMR工艺的技术阻碍,如何降低复合催化剂在脱碳再生过程中的高温、高能耗是SESMR工艺应用的主要瓶颈,开发更加低成本、高活性、高稳定性的高效能SESMR复合催化材料是今后研究的核心.
Abstract
The reaction mechanism and influenc-ing factors of sorption-enhanced steam methane re-forming for hydrogen production(SESMR)were de-scribed.The research progress of Ni-based compos-ites in SESMR process was reviewed emphatically in terms of Ni active sites,doping of additives(alu-minum,lanthanum,zirconium,magnesium and cobalt)and configuration adjustment.In addition,the regeneration of SESMR composite catalysts and the development of other composite catalysts were also introduced.It was pointed out that easy carbon deposition and high temperature sintering were the technical obstacles to the large-scale application of Ni/CaO composite catalyst in SESMR field.It was the main bottleneck of SESMR process application that how to reduce the high temperature and high energy consumption of composite catalysts in the process of decarbonization and regeneration.The de-velopment of the more low cost,high activity,high stability and high efficiency SESMR composite ma-terials was the core of the future research.
