Problems solved by technology

Due to the complex composition of cracking raw materials for the production of petroleum resin, the production process and production technology of petroleum resin are relatively backward, resulting in deep color and poor stability of petroleum resin, especially the existence of double bonds and benzene rings affects the chroma, stability and quality of the resin. Compatibility with other resins limits its range of applications

Embodiment 1

[0020] Weigh an appropriate amount of nickel nitrate, ammonium metatungstate, cobalt nitrate and cerium nitrate, and add them into deionized water to form a mixed solution of 85 mL as an impregnation solution. Weigh 100g of Al prepared according to the method of patent ZL02146005.1 2 o 3 -TiO 2 The carrier is added to the above impregnation solution for impregnation at room temperature for 4 hours. After filtration, the solid was dried at a temperature of 120°C for 10 hours, and then calcined at a temperature of 550°C for 6 hours, and the calcined solid was taken out and allowed to cool down to room temperature naturally to obtain catalyst A. Based on the total weight of the catalyst A, it contains 9.4% by weight of Ni, 11.6% by weight of W, 1.0% by weight of Co, and 1.0% by weight of Ce.

Embodiment 2

[0022] Weigh an appropriate amount of nickel nitrate, ammonium metatungstate, cobalt nitrate and cerium nitrate, and add them into deionized water to form a 95mL mixed solution as the impregnation solution. Weigh 100g of Al prepared according to the method of patent ZL02146005.1 2 o 3 -TiO 2 The carrier is added to the above impregnation solution for impregnation at room temperature for 4 hours. After filtration, the solid was dried at a temperature of 120°C for 10 hours, and then calcined at a temperature of 550°C for 6 hours, and the calcined solid was taken out and allowed to cool down to room temperature naturally to obtain catalyst B. Based on the total weight of the catalyst B, Ni is 12.4% by weight, W is 9.2% by weight, Co is 0.8% by weight, and Ce is 0.5% by weight.

Embodiment 3

[0024] Weigh an appropriate amount of nickel nitrate, ammonium metatungstate, cobalt nitrate and cerium nitrate, and add them into deionized water to form a 102mL mixed solution as an impregnation solution. Weigh 100g of Al prepared according to the method of patent ZL02146005.1 2 o 3 -TiO 2 The carrier is added to the above impregnation solution for impregnation at room temperature for 4 hours. After filtration, the solid was dried at a temperature of 120°C for 10 hours, and then calcined at a temperature of 550°C for 6 hours, and the calcined solid was taken out and allowed to cool down to room temperature naturally to obtain catalyst C. Based on the total weight of the catalyst C, Ni is 14.4% by weight, W is 7.0% by weight, Co is 1.4% by weight, and Ce is 0.5% by weight.

Abstract

The invention provides a petroleum resin hydrogenation catalyst comprising a titania-alumina composite oxide carrier, and Ni, a VIII group element, a VIB group element and a lanthanide group element which are loaded on the carrier. Under the catalysis of the catalyst, petroleum resin hydrogenation reaction has high conversion rate and selectivity, and hydrogenation petroleum resin with the good chromaticity, low bromine price and good thermal stability can be prepared. In addition, the preparation method of the catalyst is simple, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a catalyst for hydrogenation of petroleum resin and its application method. Background technique [0002] Petroleum resin is a functional resin with a relatively low molecular weight, which has the characteristics of thickening, cohesiveness and compatibility with other resins. Petroleum resins are widely used in coatings, adhesives, printing inks, rubber additives, paper additives and other fields. According to different production raw materials and properties, petroleum resin can be divided into C 5 Petroleum resin, C 9 Petroleum resin, C 5 / C 9 Copolymerized petroleum resin, etc. Due to the complex composition of cracking raw materials for the production of petroleum resin, the production process and production technology of petroleum resin are relatively backward, resulting in deep color and poor stability of petroleum resin, especially the existence of double bonds and benzene rings affects the chroma, stability and q...
