Abstract

用7种不同性能的阴离子交换树脂吸附发酵液中丙酸,考察了发酵液酸化方式及p H值对吸附量的影响,分析了不同浓度H_2SO_4的解吸情况,比较了多柱串联组合层析提高丙酸收率的可行性.结果表明,大孔弱碱性丙烯酸系阴离子交换树脂ZGD630对发酵液中的丙酸吸附量最高,采用H型阳离子交换树脂D001酸化工艺,当pH值由6.5降至3时,ZGD630树脂对发酵液中丙酸的静态吸附量从54.34 mg/g提高至110 mg/g,动态吸附量达152.5 mg/g.用4 mol/L H_2SO_4进行解吸,丙酸浓度最高达81.8 g/L,为初始发酵液的2.12倍.采用3柱串联组合层析时丙酸收率达62.15%,较单柱...
