Upgrading biomass pyrolysis gas by conversion of methane at high temperature: Experiments and modelling
چکیده انگلیسی

Biomass gasification at temperatures below 1273 K produces gas which contains methane and too much tar for Fischer–Tropsch synthesis. The aim of this study is to investigate methane conversion at high temperature. Experimental tests were performed between 1273 and 1773 K, with a mixture of gas representative of wood pyrolysis at 1100 K (main components only: CO, CO2, CH4, H2, H2O). Two different kinetic schemes were used to predict the gas composition, and PAH molecules formation. For a residence time of 2 s in the reactor, the gas must be heated to at least 1650 K to reach a methane conversion rate of 90%. A parametric study was performed at 1453 K, by varying the initial methane, steam and hydrogen contents, so as to find out which components are the most influent on methane conversion and soot production.
