Description
Summary:A method for separating primary alcohols and saturated alkanes from the products of Fisher–Tropsch synthesis is developed. The separation scheme consists of three steps:(1) the raw material is pre-separated by fractional distillation into four fractions according to normal boiling points;(2) appropriate extractants are selected to separate the primary alcohols from the saturated alkanes in each fraction;(3) the extractants are recovered by azeotropic distillation and the primary alcohols in the extract phase are purified. Based on the proposed method,the total recovery rates of the primary alcohols and the saturated alkanes are 86.23% and 84.62% respectively.
