The different scales of the thermochemical processing of ligno-cellulosic biomass: case studies

A general overview of the different routes for a thermochemical valorisation of lignicellulosic biomass is presented. The different scales involved range from the molecular level to the particle level, then to the reactor level, to the plant level and to the forest management. The work done at these levels will be illustrated by examples from two routes: the production of electrical energy and heat by gasification, and the production of BTX by pyrolysis of lignin from biorefinery followed by Hydrodeoxygenation.
