PROSPECT OF LAYERED DOUBLE HYDROXIDE DERIVED ARRAY CATALYSTS FOR HYDROGEN PRODUCTION FROM SORPTION ENHANCED STEAM REFORMING OF GLYCEROL
Hydrogen energy is considered as a promising supplement for the existing energy forms due to its high heat value,abundant reserves,and environmental friendliness.As a by-product of biodiesel production,the conversion of glycerol into hydrogen via steam reforming can meet the future requirements for renewable energy and CO2 emissions.Consequently,it has received close attention from researchers.In this paper,we summarize the development and challenges of reaction networks and thermodynamic properties of sorption enhanced steam reforming of glycerol and Ni-Ca-based bi-functional catalysts.The deactivation mechanism and modification methods of Ni-based catalytic sites and Ca-based adsorption sites are systematically analyzed.Based on the unique structural and physicochemical properties of layered bimetallic hydroxides(LDHs)and array catalysts,design and synthesis of LDHs derived Ni-Ca array catalysts is a promising approach to enhance their reactivity and stability,which exhibiting broad development prospect in hydrogen production.
