In order to construct a novel decomposition system of cellulose under subcritical water, a structured-type catalyst having AC(active carbon)-SO3H component was prepared by a combination technique consisting of a sol-gel method and a dipping technique on a plate-type substrate. From the NH3-TPD measurement, the formation of a strong acid-site was confirmed on this catalyst. The prepared catalyst demonstrated high decomposing property of cellulose under subcritical condition. The MnO2 catalyst was also prepared for the desulfurization. The crystallinity of the MnO2 layer was greatly influenced by the difference of the pretreatment condition. The pre-oxidized MnO2 catalyst has a higher performance of methanol decomposition than the pre-reduced catalyst. The possibility of the creation of the aimed continuous hydrolysis reaction field was suggested.

为了构建新型亚临界水中纤维素分解体系，采用溶胶-凝胶法和板式基底浸渍技术相结合的技术制备了含有AC（活性炭）-SO 3 H组分的结构型催化剂。从NH3-TPD测量中，证实了在该催化剂上形成了强酸中心。所制备的催化剂在亚临界条件下具有较高的纤维素分解性能。还制备了用于脱硫的MnO 2催化剂。预处理条件的不同对MnO 2层的结晶度有很大的影响。预氧化的MnO 2催化剂比预还原的催化剂具有更高的甲醇分解性能。提出了建立目标连续水解反应场的可能性。
