NOVELTY - Preparation of isohexane solvent oil using dehydroaromatization catalyst comprising alumina-composite graphene carrier involves mixing raffinate and isohexane solvent oil in the volume ratio of 3-5:1, mixing hydrogenation catalyst in the volume ratio of 120-300 at 120-180 degrees C with pressure of 2-3 MPa, separating and removing hydrogen by distillation to obtain distillate having boiling point of 58 degrees C. 98% Distillate having boiling point of less than 62 degrees C. The catalyst comprises carrier and metal active component. USE - Preparation of isohexane solvent oil using dehydroaromatization catalyst comprising alumina composite graphene carrier. ADVANTAGE - The process provides high quality material with lower impurity content.
