Embodiment 1

[0020] Weigh an appropriate amount of nickel nitrate, ammonium molybdate and silver nitrate and add them to deionized water to prepare 83 mL of mixed solution as the immersion 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-mentioned dipping solution for 4 hours at room temperature. 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. The calcined solid was taken out and allowed to cool to room temperature naturally to obtain a catalyst A. Based on the total weight of the catalyst A, the content of Ni is 13.4% by weight, Mo is 6.7% by weight, and Ag is 1.2% by weight.

Embodiment 2

[0022] Weigh an appropriate amount of nickel nitrate, ammonium molybdate and silver nitrate and add them to deionized water to prepare 95 mL of mixed solution as the immersion 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-mentioned dipping solution for 4 hours at room temperature. After filtering, 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 to room temperature naturally to obtain a catalyst B. Based on the total weight of the catalyst B, the content of Ni is 16.4% by weight, Mo is 5.2% by weight, and Ag is 0.8% by weight.

Embodiment 3

[0024] Weigh an appropriate amount of nickel nitrate, ammonium molybdate and silver nitrate and add them to deionized water to prepare 102 mL of mixed solution as the immersion 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-mentioned dipping solution for 4 hours at room temperature. 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. The calcined solid was taken out and allowed to cool to room temperature naturally to obtain a catalyst C. Based on the total weight of the catalyst C, the content of Ni is 19.7% by weight, Mo is 3.5% by weight, and Ag is 1.4% by weight.

Abstract

The invention provides a petroleum resin hydrogenation catalyst. The catalyst comprises a titanium oxide-aluminum oxide composite oxide carrier, Ni, an IB-group element and a VIB-group element, wherein the Ni, the IB-group element and the VIB-group element are supported by the carrier. Under catalysis of the catalyst, a petroleum resin hydrogenation reaction has high selectivity and a high conversion rate, and hydrogenated petroleum resin with high color purity, low bromine number and good thermal stability can be prepared. In addition, a preparing method of the catalyst is simple and low in cost and is suitable for industrial production.

Description

Technical field [0001] The invention relates to a catalyst for hydrogenation of petroleum resins and a preparation and application method thereof. Background technique [0002] Petroleum resin is C of ethylene plant 5 , C 9 The distillate is the main raw material, and the solid or viscous polymer with low molecular weight obtained after polymerization, the molecular weight is generally less than 2000. Because of its low acid value, good miscibility, low melting point, good adhesion, water resistance and chemical resistance, petroleum resins are widely used in adhesive tapes, hot melts, road coatings, inks, and rubbers. The trend of producing petroleum resins in developed countries in the world is developing towards large-scale, diversified varieties and serialized grades. In contrast, my country's petroleum resin industry is still in its infancy and is far from meeting domestic requirements. [0003] Ordinary petroleum resins usually have defects such as dark color, odor, low the...
