Catalytic hydroconversion of lignin towards aromatic compounds in a semibatch reactor

Résumé

Lignin, one of main components in lignocelulosic biomass, is considered as a perfect precursor for aromatic compounds via depolymerizing its macromolecule aromatic structure. In this framework, thermochemical processes such as gasification, pyrolysis, and hydroconversion have been largely studied for the purpose of producing biofuels or biochemicals1. Hydroconversion using a hydrotreating catalyst in a H-donor solvent under H2 pressure, is the most promising way to obtain high yield of liquid products at relative modest reaction conditions2. In this work, sulfide CoMo/Al2O3 and tetralin were selected as catalyst and solvent. Catalytic tests were implemented in a semi-batch reactor opened for gas phase, with a continuous feeding of H2 and with further functions like solvent recycling and light products removal.
