Hydrogenation – Wikipedia

Hydrogenation. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons.

High-pressure catalytic and thermal cracking of polyethylene

This suggests that high pressure of hydrogen can protect cycloparafins which are intermediate products of the reaction pathway towards aromatic, from the dehydrogenation reaction. The liquid product of catalytic hydrogenation was colourless and waxy white after cooling to room temperature, and hydrocracking without catalyst resulted in straw

Hydrogenation Reactor Pressure Control – Stability in

Hydrogenation is a chemical reaction between a compound and hydrogen. In the fine chemicals industry, hydrogenation is commonly performed in a fixed-bed catalytic reactor. An unsaturated hydrocarbon, such as an alkene or alkyne, is reduced in the presence of hydrogen to form a saturated (or more saturated) hydrocarbon.
