Development of Ni-Based Catalysts Derived from Hydrotalcite-Like Compounds Precursors for Synthesis Gas Production via Methane or Ethanol Reforming
As a favorably clean fuel, syngas (synthesis gas) production has been the focus of concern in past decades. Substantial literatures reported the syngas production by various catalytic reforming reactions particularly in methane or ethanol reforming. Among the developed catalysts in these reforming processes, Ni-based catalysts from hydrotalcite-like compounds (HTLcs) precursors have drawn consi...
متن کاملNO(x) decomposition, storage and reduction over novel mixed oxide catalysts derived from hydrotalcite-like compounds.
Effective control and removal of nitrogen oxides (NO(x)) emission from vehicles exhausts under lean-burn condition is one of the most important targets in scientific research of environmental protection. A comprehensive introduction of NO(x) storage and reduction (NSR), the most promising lean-NO(x) control technology, is given including the sum-up of NSR materials, catalytic activity and relat...
متن کاملNa Promoted Ni/γ-Al2O3 Catalysts Prepared by Solution Combustion Method for Syngas Methanation
Ni-based catalysts with different amounts of Na as promoter from 2 to 6 wt % were prepared by solution combustion method. The catalytic activity was investigated in syngas methanation reaction. Carbon oxides conversion and methane selectivity are greatly influenced by sodium loading. Adding 2 wt% Na remarkably improves catalytic activity and long-term stability, attributed to its smaller mean N...
متن کاملA comparative study on the kinetics of carbon dioxide methanation over bimetallic and monometallic catalysts
In this paper, Ni/Al and La-Ni/Al catalysts were prepared with a co-impregnation method and employed in carbon dioxide methanation reaction. The catalytic results showed that the catalyst with (10wt.%) of lanthanum and (20wt.%) nickel had the highest activity at low temperatures in CO2 methanation and the La-Ni/Al catalysts changed the reaction path by lowering its activation energy and consequ...
متن کاملKinetic studies of CO2 methanation over a Ni/γ-Al2O3 catalyst.
The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...
