Abstract


This study aimed to find a method of modification zeolite structure so it has a fit pore size
to used on bioethanol dehydration process and acquiring bioethanol quality for fuel. The method used by
heating the mixture of ethanol azeotropic and water at distillation flask which passed through on the column
filled by zeolite molecular sieve. The result showed that zeolite modifications (ZMS) have a better
characteristic for used on bioethanol dehydration process than natural zeolite. The result which obtained on
dehydration process using ZMS was better rather than commercial zeolite 3 A and natural zeolite.
Concentration of bioethanol obtained by using ZMS has increased 3,14%.
