16.6: Hydrogenolysis - Chemistry LibreTexts
Hydrogenolysis is a chemical reaction whereby a carbon–carbon or carbon–heteroatom single bond is cleaved or undergoes "lysis" by hydrogen. [1] The heteroatom may vary, but it usually is oxygen, nitrogen, or sulfur.
Hydrogenolysis - an overview | ScienceDirect Topics
Hydrogenolysis (also called hydrogenation) is a depolymerization process that includes the addition of hydrogen (as a reductant) to break down lignin macromolecule into lower oxygen-content aromatic products with high stability (Abdullah et al., 2017).
Hydrogenolysis - an overview | ScienceDirect Topics
Hydrogenolysis is a chemical process that involves breaking C-C and C-O bonds using hydrogen, often catalyzed by metal particles. It is used to selectively break these bonds in biomass-derived substrates to produce industrially important chemicals like polyols and hydrocarbons.

Difference Between Hydrogenation and Hydrogenolysis
2018年2月11日 · The main difference between hydrogenation and hydrogenolysis is that hydrogenation includes the formation of a saturated compound from an unsaturated compound whereas hydrogenolysis includes the formation of two small compounds from a large molecule.
