Research progress on Ni-based composite catalytic materials for hydrogen production by sorption-enhanced steam methane reforming
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.
