Japanese Patent JP7308061
Kind Code:
B2
Abstract:
To provide a novel method for producing a hexane solvent easily in high yield at low cost while suppressing the loss of n-hexane and isohexane.SOLUTION: Provided is a method for producing a hexane solvent which is characterized by nucleus hydrogenation-processing a distillate fraction containing a hydrocarbon of 6 carbon atoms obtained by distillation-processing a raw material oil containing a hydrocarbon of 5 carbon atoms to 7 carbon atoms as a main component obtained in a petroleum refinery process and by removing volatile components and heavy components, by 90.0 mass% to 100 mass%, using an aromatic nucleus hydrogenation catalyst containing one or more active metals selected from Group VIA metals and Group VIII metals by 0.7 to 2.0 mass% based on the catalyst and in terms of oxide conversion.SELECTED DRAWING: None
