Main characteristics of gaseous product from steam gasification of acid-hydrolysis biomass CAHR have been investigated experimentally. The comparison in terms of evolution of syngas flow rate, syngas quality and apparent thermal efficiency was made between steam gasification and pyrolysis in the lab-scale apparatus. The aim of this study was to determine the effects of temperature and steam to CAHR ratio on gas quality, syngas yield and energy conversion. The results showed that syngas and energy yield were better with gasification compared to pyrolysis under identical thermal conditions. Both high gasification temperature and introduction of proper steam led to higher gas quality, higher syngas yield and higher energy conversion efficiency. However, excessive steam reduced hydrogen yield and energy conversion efficiency. The optimal value of S/B was found to be 3.3. The maximum value of energy ratio was 0.855 at 800°C with the optimal S/B value.
已通过实验对酸水解生物质 CAHR 水蒸气气化产生的气态产物的主要特性进行了研究。在实验室装置中，就合成气流率、合成气质量和表观热效率的演变而言，对气化和热解进行了比较。本研究的目的是确定温度和蒸汽与 CAHR 比在气体质量、合成气产率和能量转换方面的影响。结果表明，在相同的热条件下，与热解相比，气化可获得更好的合成气和能量产率。高气化温度和引入适量蒸汽都导致了更高的气体质量、更高的合成气产率和更高的能量转换效率。然而，过多的蒸汽会降低氢气产率和能量转换效率。发现 S/B 的最佳值为 3.3。在最佳 S/B 值下，800°C 时能量比的最大值为 0.855。
