| Abstract: | This research was about the modified method of cassava adsorbent and the production of fuel ethanol through fixed bed adsorption. The effect of hydrochloride acid concentration,reaction time and temperature on modified experiment was analysed by orthogonal method,the best modified condition was selected. The effect of gas velocity and bed height for the production capacity and adsorption performance of modified cassava absorbent were investigated in fixed bed adsorption experiment. The results indicated tha... |
