This work aimed to investigate the application of a solid acid catalyst, a replacement for mineral acids or enzymes, to biomass conversion for further applications. Sulfonated zeolite, HSO-ZSM-5, was successfully synthesized and characterized by several analysis techniques. The obtained catalyst showed high activity and efficiency in the hydrolysis of pretreated corn cob. Moreover, the acidity of the zeolite product positively influenced the biomass conversion. The influences of reaction parameters such as catalyst loading, reaction time and temperature on the hydrolysis were also established. Under suitable conditions, a hydrolysis yield of ∼54% was achieved. This recyclable solid acid catalyst provided a promising potential for applications in many industrially important hydrolysis processes of biomass.
这项工作旨在研究一种固体酸催化剂（可替代无机酸或酶）在生物质转化中的应用，以便进一步应用。成功合成了磺化沸石HSO-ZSM-5，并通过多种分析技术对其进行了表征。所获得的催化剂在预处理玉米芯的水解中表现出高活性和高效率。此外，沸石产物的酸度对生物质转化有积极影响。还确定了催化剂负载量、反应时间和温度等反应参数对水解的影响。在合适的条件下，水解产率达到了约54%。这种可回收的固体酸催化剂在许多生物质的重要工业水解过程中具有广阔的应用前景。
