Abstract��
The separation of isopropanol-water mixture was experimentally studied by the hybrid separation process����adsorptive distillation.The fine powder of 4A molecular sieve was selectd as absorbent and glycol as liquid carrier of the powder.Under the following experimented conditions,feed composition is 85%;recycling ratio is 2��1;reflux ratio is 1��1 and solid content is 15kg/m~3,the purity and yield of isopropanol (IPA) is up to 99.7% and 95.3% respectively.
