“…The production of tar and inorganic contaminants is not evaluated by Rapagnà and Latif and Karatas and Akgun; however, the results obtained for toluene, benzene and naphthalene agree with other literature experimental sources [25,29,39]. Zhou et al reported that the concentration of NH 3 in the gasification product is between 500 to 30,000 ppm, depending on the nitrogen content of the biomass feedstock and the gasifier conditions [40]. The concentration of H 2 S reported in literature ranges from 1000 to 14,000 ppm in the raw syngas [41], and the concentration of HCl is around 750 ppm [41].…”

In the delicate context of climate change, biomass gasification has been demonstrated to be a very useful technology to produce power and hydrogen. Nevertheless, in literature, there is a lack of a flexible and fast but accurate model of biomass gasification that can be used with all the combinations of oxidizing agents, taking into account both organic and inorganic contaminants, and able to give results that are more realistic. In order to do that, a model of biomass gasification has been developed using the chemical engineering software Aspen Plus. The developed model is based on the Gibbs free energy minimization applying the restricted quasi-equilibrium approach via Data-Fit regression from experimental data. The simulation results obtained, considering different mixes of gasifying agents, were compared and validated against experimental data reported in literature for the most advanced fluidized bed technology. The maximum discrepancy value obtained for hydrogen, with respect to experimental data, is of 8%, and all the other values reached by the developed simulations, considering both organic and inorganic compounds, are in good agreement with literature data. The gas yield reached by the developed simulation is in the range of 1.1-1.3 Nm 3 /kg.

“…This may be attributed to WGSR as well as improved ‐cracking of pyrolytic volatiles and ‐tar reforming reaction catalyzed by CaO to produce more H 2 and less CO 2 . Zhou et al reported the same reason for the steam gasification of pine sawdust with CaO for H 2 concentration. A further increase in the ratio of CaO/biomass from 0.9 to 1.5, the concentration of H 2 slightly increased while the concentration of CO 2 is decreased from 4.73 vol% to 0 vol%.…”

Summary A research‐scale bubbling fluidized bed reactor (BFBR) has been assembled and used to study the steam gasification of pine needles with calcium oxide (CaO) as sorbent and catalyst. The output parameters such as syngas composition, higher heating value, lower heating value, and cold gas efficiency, have been analyzed at the operating conditions of a temperature of 650°C to 850°C, steam/biomass (S/B) ratio of 0.4 to 1.6, and CaO/biomass ratio of 0.3 to 1.5. Furthermore, an ASPEN PLUS model of BFBR has been developed using Gibbs free energy minimization technique and model values have been compared with experimental values. From the experimental results, it is analyzed that the concentration of H2 is increased from 37.02 vol% to 68.36 vol% with an increase in temperature from 650°C to 750°C at the S/B ratio of 1 and CaO/biomass ratio of 0.9 and after that, it decreased slightly. Furthermore, the concentration of CO2 in syngas captured from 5.49 vol% to 0 vol%, when the CaO/biomass ratio is varied from 0.3 to 1.5. From the result analysis, it is concluded that higher temperature and higher CaO/biomass ratio has a significant impact on H2 production while excess S/B ratio has a negative impact.

“…Fig. 5 and Table 4 show that the organic fraction of non-catalytic wood derived bio-oil consists mainly of mono and polycyclic aromatic hydrocarbons, their isomers, such as, indene, fluorene, pyrene etc., with few compounds of phenols (see peaks 7,11,12,14,16,18), furans (see peaks 19, 20, 25, 38), and an acid (see peak 8). The explanation for the elimination of the majority of the oxygenated compounds typically found in wood derived bio-oil was due to the catalytic effect of wood derived char, which was formed in the lower zone of the reformer during the non-catalytic wood run.…”

“…As it was mentioned, previous work has shown that DIS char was mainly composed of calcium carbonate. Research has explored the importance of CaO as a catalyst in biomass gasification and pyrolysis [11][12][13][14][15][16]. It is well-known that compounds of alkali and alkaline earth metals (AAEMs) are active catalysts for bio-oil upgrading, as well as, for tar cracking in gasification [17].…”
