Study on the Energy-efficient Production of Fuel Ethanol by Cassava Absorbent Jia Song1, a, Yuelin Zhu2,b, Si Zhang3,c 1School of Material Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing 100191, China 2School of Material Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing 100191, China 3School of Material Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing 100191, China asongjiacat@sina.cn, bylzhu@buaa.edu.cn, cgatx8686@163.com Keywords: fuel ethanol, cassava adsorption, ethanol dehydration, fixed-bed Abstract.
Low concentrations of ethanol is produced by cassava fermentation, high concentrations of ethanol is produced by low concentrations of ethanol distillation, then, ethanol is produced by cassava adsorbent from high concentrations of ethanol, at last, the failure of cassava adsorbent return to the fermentation process as the raw materials.
Materials and instruments Materials. 95% ethanol (V/V , C.P. ), ethanol( ≥99.7%, M/M C.P.), cassava powder(It was made by cassava planted in Guangxi and Fujian province, used as adsorbent, at a certain size, dried in oven at 105℃ for 8h and saved in dry box ) Instruments.
If the particle size is too large, the contact area between fluid and materials will descend, this will reduce adsorption capacity of water.

Three different WSLMWC products as useful materials in biomedicine and food were obtained, namely LMWC-3KDa, LMWC-5KDa, and LMWC-10KDa.
Chitosan has been considered as useful materials in many fields such as food[1], pharmaceutics[2], biomedical materials [3], and cosmetics[4] due to their biocompatibility, biodegradability, and biological activities.
Materials and methods Materials Commercial chitosan(DD: 89.2%; Mw: 437.03KDa); Oxygen with a purity of above 99%; UF membranes with molecular weight cut-off (MWCO) 3, 5, and 10KDa.

Other advantages of FDM technology are the following: easy change of printing materials; relatively low cost; high performance; high accuracy; minimal operator control; nontoxic materials; compact facility and low recycle temperatures [11].
Tensile Test Tensile test is one of the fundamental types of mechanical tests for materials.
Stretching allows getting the materials reaction on the tensile loads quickly.
Tensile tests are widely used to evaluate plastic materials, and the results are used for new materials development and for implementing quality control.

It well known that almost of the important technologically materials are not available in the nanocrystal way.
Moreover, the powders and pressing materials are easier to be obtained with low cost.
This confirms hypothesis that the microdeformations is caused by release of organic materials in the structure.
