Cobaltosic Oxide Catalysts for Catalytically Removing Hydrogen from Tail Chlorine
Abstract:
Cobaltosic oxide has been used as catalysts in dehydrogenation for tail chlorine due to the advantages of low price and security. The Co3O4/ZSM-5 was synthesized by the volume impregnation method. The catalytic dehydrogenation performance of Co3O4/ZSM-5 was investigated, the catalytic reaction of hydrogen with oxygen and chlorine was carried out in a fixed-bed, and the mixed reactant gases were prepared according to the composition and content of tail chlorine in industry: Cl2(65%-80%), N2(6-16%), O2(8%-10%) and H2(1.5%-4%). The catalytic efficiency and stability of Co3O4/ZSM-5 in dehydrogenation for tail chlorine were better than that of Co3O4. After the calcination on 300°C, the Co3O4/ZSM-5 with 1 %wt. Co3O4 shown excellent catalytic performance at 50°C, and the average conversion of hydrogen can reach up to 99.59%.

02:17Reduction 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...

The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
02:13Reduction of Alkenes: Catalytic Hydrogenation
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.

02:24Reduction 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.

As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic...
