The raw product gas produced through gasification of biomass and waste often includes tars (condensablex000D
hydrocarbons with molecular weight above 78 g/mol) and other lighter hydrocarbons that must be removedx000D
prior to producing a syngas (CO and H2) for further upgrading, for instance to avoid fouling of downstreamx000D
catalysts. This tar reforming process can be achieved through several different ways, but an input of energy andx000D
of oxidizing species is generally involved. The addition of steam and/or oxygen aims at increasing thex000D
temperature in raw product gas by partial oxidation to initiate thermal decomposition of tars but also to achievex000D
a gas temperature needed for converting all hydrocarbons to the desired syngas molecules in the secondaryx000D
catalytic zone. In this project, the potential benefit of using a combination of autothermal reforming andx000D
plasma-assisted processes will be investigated.x000D
Aplas Ltd. is developing plasma technologies for a wide range of thermochemical conversion processes,x000D
including biomass gasification and solid waste treatment. The occurrence of tar species is a problem in severalx000D
of these applications and Aplas Ltd. recognizes the need for fundamental research such as that proposed herex000D
that investigates the coupling between fluid mechanics and chemical phenomena taking place in practicalx000D
reformer geometries.
