Study on the Energy-efficient Production of Fuel Ethanol by Cassava Absorbent

The energy-efficient production of fuel ethanol though fixed-bed absorption by use of cassava absorbent was studied. The cassava absorbent was desiccated to absorb the water in the ethanol, making its quality score from 75%similar to 95% up to 99.5%.The absorption performance of cassava power was investigated from the aspects of power size ,quality ratio of absorbent and solution, temperature of absorption and the ratio of airflow. The analysis of the result indicated that the best technological parameter for the above method were as follows: particle size was between 1.6mm and 2.5mm,quality ratio of absorbent and solution was equal to1:6, temperature of absorption was 90 degrees C and the ratio of airflow was 105 degrees C on the characterized temperature.
