In Karamay petrochemical company, reformate raffinate (hexane content 15%~36%) is used as raw material to produce n-hexane. Firstly, the distillation separation of reformate raffinate is carried out to gain the fraction (n-hexane content 70%~80%),then 705 hydrogenation catalyst is used to remove impurities such as sulfur and nitrogen, and MH-6A benzene hydrogenation catalyst is used to remove saturated hydrocarbons, finally qualified n-hexane is gained. This technology has high catalytic activity, long service life without regeneration, mild reaction conditions, simple process and high product appreciation. At the same time, produced n-hexane has good quality, reaches to the level of the same product at abroad;the direct economic benefit is remarkable.
