Abstract

Pervaporation of ethanol dehydration can be done using membrane technology, one of which is by using cellulose acetate (CA) membrane which is made from non-wood cellulose such as sugarcane bagasse. The research objective was to compare commercial CA membranes and bagasse pulp CA membrane modified Lampung natural zeolite, and to study the effect of the Lampung natural zeolite concentration on the performance of CA membrane. The polymer used is a commercial CA and bagasse pulp CA with a concentration of 20% w / v. the modification of Membrane with the addition of Lampung natural zeolite with various concentrations 10% w-CA, 20% w-CA, 30% w-CA. Membrane characterization using (FTIR) showed that the CA membrane has been modified by Lampung natural zeolite and the results of Scanning Electron Microscopy (SEM) showed that the commercial CA membrane modified has a dense pore that is higher than bagasse pulp CA membranes modified.The highest purity ethanol in a commercial CA membranes modified by Lampung Natural Zeolit obtained on the addition of 30% w-CA zeolite concentration and the purity of ethanol 99.27%, the value of flux 2.819 kg / m2.h and selectivity 111.080. For bagasse pulp CA membranes modified, the purity of ethanol obtained of 98.10%, the value of flux 2.999 kg / m2.h, and the value of selectivity 30.760.
