Decomposition and recycle of waste textile material using ultra-high temperature and pressure steam explosion

为了有效利用未利用的纤维素原料，采用超高温高压蒸汽爆破法对微晶纤维素粉（MC）和铜氨人造丝纤维（BEMCOT）进行水解，制备葡萄糖。当蒸汽压力为62 atm，汽蒸时间为1 min时，MC的水溶性糖得率最高，为52.8%。此外，水溶性糖的最大产率，67.7%，获得在蒸汽压力为60大气压和蒸汽时间为1分钟的BEMCOT。

Hydrolysis of cellulosic materials, i.e. microcrystalline cellulose powder (MC) and cuprammonium rayon fiber (BEMCOT), to glucose was carried out by steam explosion treatment with ultra-high temperature and pressure steam aiming at an effective usage of unutilized cellulosic materials. The maximum yield of water soluble sugars, 52.8%, was obtained at a steam pressure of 62 atm and a steaming time of 1 min for MC. Furthermore, the maximum yield of water soluble sugars, 67.7%, was obtained at a steam pressure of 60 atm and a steaming time of 1 min for BEMCOT.
