Description:
The content of n-hexane in straight-run gasoline, Platinum Reforming raffinate, or wet natural gas is about 1-15%. Industrial production is mainly separated from the raffinate oil (containing hexane 11%-13%) of the Platinum Reforming Unit. The raffinate oil is separated by distillation to remove light components and reconstituted to obtain a fraction containing 60%-80% n-hexane. Double-column continuous rectification is adopted, hydrogenation is carried out with 0501 type catalyst to remove benzene and other unsaturated hydrocarbons, and qualified n-hexane is obtained. The United States also uses the adsorption separation method to prepare n-hexane.
They are obtained by fractionation in petroleum fractions.
