Abstract

Biomass gasification technology is used as one of the energy sources due to its low effects on the environment and reducing pollution. This technology is able to produce gas with the highest content of hydrogen. Hydrogen can be used as a fuel and an important carrier of energy due to its stability and lack of negative effects on the environment. This study used wood sawdust as biomass to produce syngas and investigated the effect of adding carbon dioxide and methane gases to the Gibbs reactor. Aspen Plus software is used for steam gasification modelling. According to the results, the performed modelling is able to predict the experimental data well. When the carbon dioxide to biomass ratio (C/B) rises, the mass flow rates (MFR) of hydrogen and Methane fall while those of carbon dioxide and carbon monoxide increase. The decrease in hydrogen MFR with changes from C/B = 0 to C/B = 1 in modes a, b, c and d is equal to 17.51, 16.39, 29.57 and 24.84%, respectively. The mass flow of hydrogen increases as the Methane to biomass ratio (M/B) rises, whereas the MFR of carbon dioxide shows a declining pattern. As M/B increases from 0 to 1 in the Gibbs reactor for modes a, b, c and d, the hydrogen MFR increases by 265, 243, 297 and 305%, respectively.

考虑参数研究的CO2和CH2添加对生物质可再生能源蒸汽气化合成气生产的影响

摘要

生物质气化技术因其对环境影响小、减少污染而被用作能源之一。该技术能够生产氢气含量最高的气体。氢由于其稳定性且对环境无负面影响，可用作燃料和重要的能源载体。本研究使用木屑作为生物质生产合成气，并研究了向吉布斯反应器中添加二氧化碳和甲烷气体的效果。Aspen Plus 软件用于蒸汽气化建模。根据结果​​，所进行的建模能够很好地预测实验数据。当二氧化碳与生物质的比率（C/B）升高时，氢气和甲烷的质量流量（MFR）下降，而二氧化碳和一氧化碳的质量流量（MFR）增加。在模式a、b、c和d中，随着C/B = 0到C/B = 1的变化，氢MFR的降低分别等于17.51、16.39、29.57和24.84%。随着甲烷与生物质比率 (M/B) 的增加，氢气的质量流量增加，而二氧化碳的 MFR 显示出下降的模式。对于模式 a、b、c 和 d，当吉布斯反应器中 M/B 从 0 增加到 1 时，氢气 MFR 分别增加 265%、243%、297% 和 305%。
