Zusammenfassung:Provided is an n-heptane production method including: a step of distilling a feed containing C6-, C7, and C8+ hydrocarbon components, removing the C8+ and C6- hydrocarbon components, and separating the C7 hydrocarbon component; a step of adding the separated C7 hydrocarbon component to a hydrogenation apparatus and hydrogenating the separated C7 hydrocarbon component; a step of adding the hydrogenated C7 hydrocarbon component to a simulated moving bed (SMB) apparatus and separating the hydrogenated C7 hydrocarbon component into an extract containing n-heptane and a raffinate containing other components; and a step of distilling the extract and separating the n-heptane in an extract column, wherein a purity of the produced n-heptane is 98 wt% or higher.
