Embodiment 1

[0013] (1)CuO-Ni / TiO 2 Preparation: Add copper oxide and nickel to 8 times the weight of water, fully disperse and let it stand for 1 hour, then ultrasonically treat it at an ultrasonic frequency of 40kHz and a power of 100W for 30 minutes, then add nano-titanium dioxide to the treatment solution, mix well and then place it in a microwave at a frequency of 2450MHz , microwave treatment at 700W for 10min, dry the resulting mixture at 100-110°C for 12h, and then roast at 500-600°C for 3h to obtain CuO-Ni / TiO 2 ;

[0014] (2) Catalyst preparation: the prepared CuO--Ni / TiO 2 Grind into powder, add an equal amount of water and stir to make a paste, then add carrier nano-alumina, mix well, and then ultrasonicate for 30 minutes at an ultrasonic frequency of 40kHz and a power of 50W. After the treatment, stand at 0-5°C for 3 hours , and then transferred to room temperature to allow the mixture to return to room temperature naturally, then dried at 100-110°C for 8 hours, and finally ...

Abstract

The invention discloses a high-selectivity petroleum resin hydrogenation catalyst and relates to the technical field of catalyst preparation. Copper oxide, nickel and nanometer titania are used as active components, nanometer aluminum oxide is used as a carrier, the mass ratio of the active components to the carrier is 2:8, and the mass ratio of copper oxide to nickel to nanometer titania is 2:0.5:8. Nanometer titania is loaded with copper oxide and nickel firstly to obtain CuO-Ni / TiO2, and then nanometer aluminum oxide is evenly loaded with CuO-Ni / TiO2 to prepare the catalyst. The catalyst has the advantages of being high in activity, conversion rate, selectivity and stability, the defects of dark color, bad smell, low thermal oxidation stability, poor cohesion and poor compatibility of petroleum resin can be effectively overcome, and then the application range of petroleum resin is widened.

Description

Technical field: [0001] The invention relates to the technical field of catalyst preparation, in particular to a highly selective petroleum resin hydrogenation catalyst. Background technique: [0002] Petroleum resin is C 5 、C 9 The distillate is the main raw material, and it is a solid or viscous low molecular weight polymer obtained after polymerization. Because petroleum resin has the characteristics of small acid value, good miscibility, low melting point, good adhesion, water resistance and chemical resistance, it is widely used in adhesive tapes, hot melt adhesives, road coatings, inks and rubbers, etc. . Ordinary petroleum resins have disadvantages such as dark color, odor, low thermo-oxygen stability, poor cohesive force and compatibility, etc. Works around this problem nicely. [0003] The hydrogenation of petroleum resin is difficult, and the operating conditions of the hydrogenation process are harsh. At present, my country's demand for hydrogenated petroleu...
