Creation of continuous hydrolysis system of cellulose by combination of subcritical water and honeycomb-type structured catalyst

为了构建亚临界水条件下纤维素的新型分解体系，采用溶胶-凝胶法和浸渍法制备了具有AC（活性炭）-SO3H组分的结构型催化剂。NH3-TPD测定证实了该催化剂上形成了强酸位。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。制备了MnO2催化剂进行脱硫。预处理条件的不同对二氧化锰层的结晶度有较大影响。预氧化MnO2催化剂的甲醇分解性能优于预还原MnO2催化剂。提出了建立目标连续水解反应场的可能性。

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.
