Ethanol Purification Using Active Natural Pahae Zeolite by Adsorption Distillation Method

Abstract

A research of ethanol purification using Natural Pahae Zeolite as active material has been carried. This research aims to analize the process of ethanol purification by using adsorption distillation method followed analyze by the influences of the variants of it's variables. Natural Pahae Zeolite which has been chemically activated by H 2 SO 4 6% and physically by the variants of calcining temperatures at 500°C, 600°C, 700°C, 800°C and 900 °C. Then, continued by applying an adsorbent in the ethanol purification with the various time in 30 minutes, 45 minutes, 60 minutes, 75 minutes, and 90 minutes. The final ethanol which has been purified then analized by using Gas Chromatography (GC) to classify the level of it's purity. From the result of the research, the most effective process in ethanol purification was the process of adsorption distillation by using natural pahae zeolite as the adsorbent which has been activated at 700°C in 60 minutes and heated at 78° C which resulted ethanol as 93.28%.
