| In order to investigate the effects of iron oxide on the thermal decomposition of solid fuels, we have performed experiments in an isothermal flow reactor using the model compound catechol (ortho-dihydroxybenzene), a phenol-type compound representative of coal, wood and biomass. Iron oxide is an inorganic component in coal and wood, which is used commercially during combustion and gasification of solid fuels. It possesses catalytic properties that enhance conversion and affect product formation. In this study, iron oxide is placed inside the flow reactor where a stream of sublimed catechol enters in a 0.15% oxygen carrier gas. Condensed-phase and gas-phase products are collected at the other end of the reactor and analyzed. The results of the 300 to 600 oC experiments show that iron oxide causes significant effects on the catechol conversion as well as the formation of aromatic ketones and polycyclic aromatic hydrocarbons (PAH). |
