Abstract

The invention relates to a preparation method for a hydrogenated C9 petroleum resin. A technical point of the method is that: the method comprises a desulfurization process and a hydrogenation process. Steps of the desulfurization process comprise: pouring cyclohexane, toluene, and mixed aromatic hydrocarbon into a mixer, and completely mixing; heating the mixed resin solution, and adding the heated resin solution and hydrogen gas to a desulfurization hydrogenation reactor; carrying out a desulfurization reaction under an effect of a desulfurization catalyst; and carrying out high fraction separation, low fraction separation, gas stripping with a gas stripping tower, and hydrogen sulfide removing to obtain a desulfurization resin liquid. Steps of the hydrogenation process comprise: heating the desulfurization resin liquid, and adding the heated desulfurization resin liquid and hydrogen gas to a hydrogenation reactor; carrying out a hydrogenation reaction under an effect of a hydrogenation catalyst; carrying out high fraction separation and low fraction separation to obtain a hydrogenation resin liquid; and carrying out distillation on the hydrogenation resin liquid to obtain the hydrogenated C9 petroleum resin finished product. The desulfurization catalyst adopts cobalt and molybdenum as active ingredients, and the hydrogenation catalyst adopts nickel, tungsten and copper as active ingredients. The method of the present invention has characteristics of simple process, good decolorization effect, stable quality, wide application range, and the like.

Description

technical field [0001] The present invention relates to C 9 The technical field of deep processing of petroleum resin modification, specifically a kind of hydrogenated C 9 Preparation method of petroleum resin. Background technique [0002] C 9 Petroleum resin is a very important chemical raw material. C 9 Petroleum resin is cracked C by-product of ethylene plant 9 Distillation is a high molecular compound made from the main raw material. The relative molecular mass is generally 400-3000. It is a glassy thermoplastic solid at room temperature. Because its structure does not contain polar groups, it has good chemical properties in hydrocarbon solvents. Stability, C. 9 Petroleum resin also has the advantages of good viscosity, good plasticity, and low thermal conductivity, and is widely used in ink, coating, adhesive, rubber and other industries. [0003] due to C 9 The distillate contains diolefins, aryl olefins and other components, so that the obtained petroleum res...
