Decomposition of biomass gasification tar model compounds over waste tire pyrolysis char

Abstract Gasification of biomass produces a syngas containing trace amounts viscous hydrocarbon tar, which causes serious problems in downstream pipelines, valves and processing equipment. This study focuses on the use tire-derived pyrolysis char for tar conversion using model compounds representative tar. The catalytic decomposition compounds, including methylnaphthalene, furfural, phenol, toluene, over tire was investigated fixed bed reactor at temperature 700 °C 60 min time stream. influence temperature, reaction time, porous texture, acidity with methylnaphthalene as compound. Oxygenated were found to have higher than those single or multi-aromatic ring. reactivity followed order furfural > phenol toluene methylnaphthalene. presence much thermal cracking. Gas production increased dramatically introduction char. H 2 potential studied be range 40%–50%. activity naphthalene removal compared two commercial activated carbons possessing very well-developed texture. results suggest that Brunauer-Emmett-Teller surface area carbon cracking is negligible mineral content samples.
