| Summary: | This study observed the
use of activated carbon adsorbent in adsorptive distillation to increase
ethanol concentrations. The different ethanol influent concentrations
considered were 90% v/v and 95% v/v, and the weight of activated carbon
adsorbent used was 25 g and 50 g. The temperature was maintained at the boiling
point under a pressure of 1 atm, and observational data were collected every 5
to 10 minutes and tested using a densitometer. The result of this study
indicates that the distillation-adsorption technique using activated carbon
exceeded its azeotropic point and produced fuel-grade ethanol that satisfied
all requirements. The maximum water content in the ethanol-water mixture was
found to be approximately 1% v/v. The highest ethanol concentration, 99.49%
v/v, was achieved in 15 minutes utilizing 50 g of Calgon-activated carbon and
beginning ethanol that was 95% v/v. Meanwhile, the lowest ethanol concentration
of the other research variants was achieved with 25 g of Haycarb activated
carbon and 90% v/v starting ethanol at 98.27% v/v. |
