“…At lower temperatures, the efficiency of gasification is lower, and the tar content of the gas is excessive. 8 The A/F rate and S/F rate are 0.2 due to the high content of O 2 in biomass residues. The gasifier temperature is 877 °C for the developed model.…”

In this study, gasification performance and importance of hydrogen production using waste of a tea factory were evaluated. A mathematical model was developed for the gasification system, which includes a water gas shift reactor used for hydrogen purification. The gasifier temperature was 877 °C for the developed model. The model has been validated against experimental data from an 80 kW t h cylindrical downdraft gasifier, given in the literature for syngas composition for three different air-to-fuel ratios. With the developed model, hydrogen production from tea wastes was achieved to yield a higher level by additionally using a water gas shift reactor. Tea waste (1000 kg) was gasified and after the hydrogen purification process, a total of 4.1 kmol hydrogen was achieved, whereas the amount would be 2.8 kmol gas hydrogen if a normal gasification method were used. The validity of the developed model was verified by comparing the experimental results obtained from the literature with the results of the model under the same conditions. After verification of the developed model, the effect of the moisture content of the biomass and the air/fuel ratio on the composition of the product gas were investigated. These investigations were also confirmed by experimental data. The results show that it is important to convert biomass waste into a clean energy source of hydrogen to minimize its environmental impact.

“…We assume that all of the reactions in biomass gasifiers are thermodynamically balanced with each other. In order to avoid unnecessary repetition, we do not give these reactions in this article, but one can find them in Table 1 [33]. Furthermore, we assume that the process of gasification is a single reaction in this model.…”

“…Simulation of gasification processes help to observe a comprehensive understanding of the chemical and physical mechanisms of the gasification systems, therefore leads to the design of new systems in the best possible way which saves money and time. Numerous studies have been performed on simulation and modeling of FBG systems [32][33][34]. Gasification performance was investigated in different particle size of biomass wastes, thermal conditions and with various catalysts [35,36].…”

In this study, hydrogen production performances of groundnut shells in a circulating fluidized bed gasifier is evaluated by employing a previously developed and validated model. Basically, we simulate a circulating fluidized bed gasification system that is connected to a water-gas shift reactor, for hydrogen purification with the gasifier temperature of 1150 K. We find that the amount of hydrogen gas produced from circulating fluidized bed gasification of groundnut shells increases from 49.25 kmol to 68.83 kmol (per 1000 kg of raw groundnut shells) when the gasifier is integrated with water-gas shift reactor. We observe that it is possible to obtain a high yield of hydrogen gas from the gasification of groundnut shells. Therefore, we conclude that the groundnut shell is a remarkable feedstock for bioenergy.
