Simultaneous catalytic H-2 production and CO2 capture in steam reforming of toluene as tar model compound from biomass gasification

Popis výsledku v původním jazyce

During biomass gasification in a fast internal circulating fluidized bed (FICFB) reactor hydrogen production is strongly influenced by the physicochemical properties and ability of the catalyst to transform the organic fraction (tar molecules), considered as pollutant and produced along the process. The hydrogen production can be also favored by the sorption of CO2 formed during biomass gasification. In this work, two types of bi-functional sorbents/catalysts were prepared taking into account the high attrition resistance required in this type of reactor. Olivine was chosen as catalyst and support of CaO or CaO-Ca12Al14O33 (CaO-CaAl) used as CO2 sorbent phases. The bi-functional materials and olivine were characterized by SEM, BET, XRD, TPR and Mossbauer spectroscopy. The SEM and BET analyses showed that the higher content of CaO-CaAl on olivine allowed having larger pore volume and smaller pore size than CaO/olivine. XRD and TPR showed that the formation of alpha-Fe2O3 by oxidation of
