Hydrogen enriched syngas production via gasification of biofuels pellets/powders blended from olive mill solid wastes and pine sawdust under different water steam/nitrogen atmospheres

Abstract : In this paper we focused on the gasification of biomass charcoal using a macro TG under the CO2 gasifier agent mixed with nitrogen at different mass molar fractions; 40%, 70% and 100% respectively. Moreover, the gasification tests were conducted at different isothermal temperatures; 750°C, 800°C, and 900°C respectively. For this purpose, two densified residues were selected; the exhausted olive mill solid wastes (EOMSW) and the pine sawdust (PS). Then, four different samples were prepared from these residues when investigating the impregnated and the non-impregnated samples using the olive mill waste water (OMWW) as by-product for the impregnation process. A comparison between obtained results during this current study and those obtained during our latest study when using steam as gasifier agent was carried out. We observe that the mass loss profiles meet the usual lingo-cellulosic gasification behaviours. Moreover, the increase of the isothermal temperatures or of the CO2 percentage affects positively the conversion, the gasification rate and the char reactivity. It is worth noting that the CO2 agent acts differently by comparison to the steam. Indeed, the gasification process using steam is found to be faster and more reactive.
