Preparation of Molecular Sieving Carbon from Saran Waste

Separation of Butane and Isobutane by a Fixed-bed Adsorber

Abstract

Dynamic adsorption characteristics in fixed beds of various molecular sieving carbons prepared from Saran waste were studied for butane and isobutane system.
It was found that static adsorption capacity does not necessarily correspond to dynamic separation ability.As adsorption rate affects significantly on separation efficiency, molecular sieving carbon with relatively enlarged pores is suitable in fixed bed adsorption.It was found that preferable amount of coal tar pitch added and heat treatment temperature of molecular sieving carbon were about 5wt% and 800-900°C, respectively.
