N-hexane production process
Mar 21, 2018

The content of n-hexane in straight run gasoline, platinum reforming raffinate or wet natural gas is about 1%-15%. The current industrial production is mainly separated from the raffinate oil (11%-13% of hexane) of the platinum reformer. The raffinate is separated by rectification and light components and recombination are removed to obtain a fraction containing 60%-80% of n-hexane. The continuous distillation of the two towers, and then hydrogenation by the 0501-type catalyst to remove benzene and other unsaturated hydrocarbons, qualified n-hexane. In the United States, n-hexane is also prepared by adsorption separation.
