Abstract:

Bioethanol (Ethanol or ethyl alcohol) C₂H₅OH is a clear colorless liquid, which is biodegradable, has low toxicity and does not cause major pollution when contacted in the air. However, to produce bioethanol is not enough, special treatment is needed to produce high bioethanol. Therefore, there is a need for a new method with high economic value and better in bioethanol purification, one of which is bioethanol purification using an adsorbent, In this study, bioethanol purification will be carried out using Zeolite adsorbent with Adsorption-Distillation method.  With the aim of knowing the Adsorption-Distillation process by using zeolite adsorbent on bioethanol purification to obtain high bioethanol levels as well as to find out whether bioethanol purification with Adsorption-Distillation process is an efficient method and to get the results of bioethanol purity levels whether it meets the Fuel Grade Ethanol standard after purification by Adsorption-Distillation method. In this study, the optimum level of bioethanol after the adsorption-distillation process was obtained at 44.8424% at 90 minutes with a volume of 125 ml of bioethanol and the minimum level obtained after the adsorption-distillation process was 34.0570% of the previous level of 33.6977%.
