Plasmaassisted conversion of pyrogas

Abstract

Pyrogas - a fuel gas formed from the pyrolysis or gasification of Biomass or Coal - usually contain large amounts of heavy hydrocarbons (tar) and unreacted light hydrocarbons (CH4, C2H2, C2H4, C2H6), that decreases its value and require significant cleaning. The conversion of Pyrogas into synthesis gas (a combination of CO and H2) in varying quantities in the presence of Plasma discharge in the form of Gliding arc Plasma is effectively demonstrated and studied. A special low current gliding arc plasma reactor, 'plasmatron', is designed to provide plasma discharge in a reforming zone for reforming reactions. The Gliding arc plasma reactor (plasmatron) is a non thermal reformer which offers better selectivity, reactivity and efficiency compared to conventional catalytic reformers.
