Abstract
In production of ethanol by yam fermantation, mathanol is generated, that influences the quality of ethanol. Adsorption by NaA zeolite may be beneficial to separate it. In this paper, the adsorption equilibrium for pure methanol, water and their mixture on NaA zeolite were experimentally measured, the data obtained were well correlated in Langmuir isotherm form. Breakthrough curves of methanol and water from their ethanol solution on NaA zeolite bed were also measured, the effects of flow rate, temperature and concentration of adsorbed components on the shape of breakthrough curve were discussed.
