high pressure autoclave for catalytic hydrogenation reaction


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

What is Catalytic Hydrogenation? - Definition from

Corrosionpedia explains Catalytic Hydrogenation. Hydrogenation reactions use a catalyst such as palladium, platinum, rhodium, ruthenium or Raney nickel, and are performed at elevated temperature and pressure. Catalytic hydrogenation occurs on the surface of the metal catalyst. Transition metals adsorb hydrogen molecules and pi systems.

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.
