Embodiment 1

[0030] Preparation of Ni / MgO catalyst: 20 g of nickel acetate was dissolved in 180 mL of distilled water to prepare a 10% nickel acetate aqueous solution. Then, 27g of high-purity magnesium oxide powder was added into the above aqueous solution of nickel acetate under the condition of stirring at 25°C, and stirred for 18 hours. Prepare an ammonia solution with a mass concentration of 15%, add 20mL to the above mixture, and age at 85°C for 20h, filter, wash, and dry at 110°C. After reduction in hydrogen at 500°C for 8 hours, a nickel-supported magnesia catalyst can be obtained, and its transmission electron microscope photo is shown in figure 1 .

[0031] Catalyst performance test: A tank reactor was used to apply the catalyst to C9 resin hydrogenation. The reaction conditions were: 10g raw material, 50g cyclohexane solvent, 0.3g catalyst, and react for 5h. The result of the reaction is as follows:

Abstract

The invention discloses a catalyst for catalyzing the hydrogenation of C5 and C9 petroleum resins as well as a preparation method and application thereof. The catalyst adopts nickel nanoparticles as active ingredients and magnesium oxide as a carrier. The preparation method comprises: (1) preparing a nickel-salt solution, under a stirring condition, adding the magnesium oxide carrier into the nickel-salt solution, and stirring for 0.5 to 24 h at 25 to 100 DEG C; (2) preparing a precipitator solution, under a stirring condition, adding the precipitator solution into a mixture obtained in the step (1), and stirring for 0.5 to 50 h at 25 to 100 DEG C; and (3) filtering a mixture obtained in the step (2), drying a filter cake, then placing the filter cake into a tubular furnace, and reducing the filter cake to obtain the magnesium oxide-loaded nickel catalyst. The prepared nickel / magnesium oxide catalyst has the characteristics of high catalytic activity, good stability, easiness in separation and the like; and the petroleum resin is hydrogenated under a moderate reaction condition, the degree of unsaturation of the resin is remarkably decreased, the hue is obviously improved, and the industrialized production is realized.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanometer metal catalysts, in particular to a C5 and C9 petroleum resin hydrogenation catalyst and a preparation method thereof. Background technique [0002] Petroleum resin is a thermoplastic resin produced by polymerization of C5 and C9 fractions in the by-products of ethylene cracking. It can generally be divided into: aliphatic hydrocarbon resin (C5), aliphatic hydrocarbon-aromatic resin (C5 / C9), aromatic hydrocarbon resin (C9 ) and dicyclopentadiene resin (DCPD). Due to its excellent water resistance, acid and alkali resistance, weather resistance and light aging resistance, petroleum resin is widely used in the fields of paint, ink, coating, adhesive and rubber. Affected by the composition of raw materials, petroleum resin is generally light yellow or even reddish brown, and its light and heat stability is poor, which largely limits its application. Through catalytic hydrogenation ...
