Abstract
Provided are a method for producing paraffins and an apparatus for producing paraffins, in which each high-purity paraffin can be produced with high efficiency while complicated operations such as distillation are not carried out. An apparatus for producing paraffins includes a separation and recovery unit and a hydrogenation unit. The separation and recovery unit has a separator containing silver ions, and separates impurities from raw material olefins containing olefins as main components and recovers the olefins, by bringing the raw material olefins into contact with the separator. The hydrogenation unit brings the olefins recovered by the separation and recovery unit into contact with hydrogen in a presence of a catalyst and subjects the recovered olefins to a hydrogenation reaction, thereby obtaining high-purity paraffins.
