Impact of Carbonization on the Combustion and Gasification Reactivities of Olive Wastes

摘要: As an alternative to biomass, biochar is known as a promising candidate replace or co-process with coal solid fuel. In this study, biochars were obtained from pyrolysis of olive tree pruning (OP) at different temperatures and duration in order investigate their possible use combustion gasification processes alone lignite. Steam experiments raw blends lignite conducted two-stage reactor 850 °C produce hydrogen-rich gas. The behavior fuels was investigated using thermogravimetric analyzer. temperature more effective than on the yield properties biochar. Biochars above 350 had aromatic structure higher fixed carbon content. Gasification efficient that due its high content, homogeneous properties, minimized tar formation. Hydrogen increased increase potassium contents biochars. Slagging fouling indices indicated tendency slagging during alone. For containing OP produced low temperatures, antisynergistic effect observed, lowering reactivity. contrast, no interaction found for blend high-temperature
