| Abstract: | In the self-designed fixed bed,preparation of fuel ethanol by adsorption dehydration of 95% ethanol using sweet potato as adsorbent was studied.Temperature changes of fixed bed in the process of adsorption was measured,and the effects of superficial velocity into bed,bed height,particle size on the breakthrough carve were studied.Combined with the temperature changes in fixed bed,the calculation methods for traveling speed of adsorption wave,length of mass transfer area were given.Moreover,the process of preparation for fuel ethanol in fixed adsorption bed using sweet potato as adsorbent was put forward. |
| Keywords: | sweet potatoes fuel ethanol adsorption dehydration fixed bed |
