- Bioethanol is an alcohol substance which can be obtained by biomass fermentation process by means of Saccharomyces Cereviceae help. Adsorption is a separation process where the components of a fluid phase moves to the absorbing surface of the solid (adsorbent). This research aims to examine the process of bioethanol purificationusing adsorption and distillation process by the influence of variations of the variables. In the distillation process produces ethanol conyent that is not too high, so it needs to be atudied a process that can increase the purity of bioethanol with distillation adsorption process. Bioethanol purification process using zeolite as adsorbent with 4 variables change in the adsorption process, namely: the type of zeolite, stirring time, residence time, and heavy of zeolite. Whereas ondistillation adsorption process using 4 variables change, namely: the type of zeolite, temperaturem weight of zeolite, and processing time. From the results most effective process for ethanol purification is distillation adsorbtion process with zeolite 4A adsorbent weighing 100 grams, the process temperature 78oC, processing time 50 minutes. Levels of ethanol produced was 98,42%.
