Catalytic steam gasification of palm kernel shell is investigated to optimize operating parameters for hydrogen and syngas production using TGA-MS setup. RSM is used for experimental design and evaluating the effect of temperature, particle size, CaO/biomass ratio, and coal bottom ash wt% on hydrogen and syngas. Hydrogen production appears highly sensitive to all factors, especially temperature and coal bottom ash wt%. In case of syngas, the order of parametric influence is: CaO/biomass>coal bottom ash wt%>temperature>particle size. The significant catalytic effect of coal bottom ash is due to the presence of FeO, MgO, AlO, and CaO. A temperature of 692°C, coal bottom ash wt% of 0.07, CaO/biomass of 1.42, and particle size of 0.75mm are the optimum conditions for augmented yield of hydrogen and syngas. The production of hydrogen and syngas is 1.5% higher in the pilot scale gasifier as compared to TGA-MS setup.
采用热重-质谱联用（TGA-MS）装置研究了棕榈仁壳的催化蒸汽气化，以优化用于制氢和合成气的操作参数。响应面法（RSM）用于实验设计和评估温度、颗粒大小、CaO/生物质比以及煤底灰重量百分比对氢气和合成气的影响。氢气的产量对所有因素都非常敏感，尤其是温度和煤底灰重量百分比。就合成气而言，参数影响的顺序为：CaO/生物质＞煤底灰重量百分比＞温度＞颗粒大小。煤底灰具有显著的催化作用，这是由于其中存在 FeO、MgO、AlO 和 CaO。在 692°C 的温度、0.07 的煤底灰重量百分比、1.42 的 CaO/生物质比和 0.75mm 的颗粒大小条件下，氢气和合成气的产量得到了最大提高。与 TGA-MS 装置相比，在中试规模气化炉中，氢气和合成气的产量提高了 1.5%。
