Hydrogen activation
WebThe reaction of hydrogen sulfide and oxygen with activated carbon as a catalyst is as follows: 2H 2 S + O 2 → 2S + 2H 2 O. This reaction is divided into the following processes: (1) The water in the gas is absorbed by the activated carbon and forms a water film on its surface; (2) Hydrogen sulfide and oxygen diffuse into the pores of the ... Web7 mrt. 2002 · Hydrogen is an important metabolite for many microrganisms. H 2 is either produced or consumed by hydrogenase enzymes, according to the reaction: H 2 ⇌2 H + …
