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.

Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
