“…Air gasification of mixed fuels (biomass and coal-coke) produced a syngas with increased H2 concentration as the temperature increased (Lapuerta et al 2008). Syngas (H2 and CO) yield, in terms of mass fraction, was favored by high-oxidation zone temperature during air gasification of dry refinery sludge using an updraft gasifier (Ahmed and Sinnathambi 2013). At sufficient residence time, increasing the gasification temperature led to higher H2 yields, CO efficiency, and higher heating value (HHV) of the product gas (Aljbour and Kawamoto 2013).…”

The astronomical increase in global energy demand makes locating energy sources other than fossil fuels worthwhile. The use of tropical biomass wood waste as a renewable energy source was investigated in this study. The thermal conversion analysis of Albizia gummifera (ayinre) was carried out in a thermobalance reactor via steam gasification under varying temperature (700 to 1000 °C) and steam partial pressure (0.020 to 0.050 MPa). The experimental data was evaluated using three gas-solid reaction models. The modified volume reaction model (mVRM) gave the overall highest coefficient of determination (0.9993) and thereby the best conversion prediction. The observed char activation constant rates (from paired reaction conditions) indicated, on average, an increase in reactivity as the parameters increased. The results showed that the activation energy of the mVRM gave the lowest value (32.54 kJ/mol) compared with those of the shrinking core model (SCM) and the volume reaction model (VRM) (49.29 and 49.89 kJ/mol, respectively).
