Challenges in CO2 Reforming with Methane for Production of Hydrogen Rich, Stable Syngas

Abstract

Production of hydrogen rich syngas is one of the industrial important reactions as a feedstock for many energy applications. This reactor has environmental benefit as it consume CO2 which is hazardous and creates globe warming. The most economical way to produce syngas is through transformations of hydrocarbons by several reforming process by both fixed bed and fluidized bed reactors. As many challenges are from catalyst side and setting of reaction parameter to get stable activity for long time on stream. Catalyst synthesis method, characterisation techniques to confirm crystallinity, morphology, metallic state with percentage of dispersion, amount of the acidic and basic sites and surface area with pore volume are influence the degree of deactivation. The parameters of the reaction are composition of feed (methane to oxygen, CO2 to methane ratio), temperature, amount of the catalyst, type of the reactor will influence the stable production of syngas. Deactivation by carbon formation and sintering of metals can be remedied by addition of promoters by various synthesis methods. By optimising the parameters need to set benchmark for hydrogen rich syngas production.
