Problems solved by technology

These catalysts are characterized by high activity, but they are more sensitive to impurities in petroleum resins and are easily poisoned and deactivated
[0007] To sum up: the current C 5 There are mainly two types of catalysts for petroleum hydrogenation resins, one is a noble metal hydrogenation catalyst, which has good hydrogenation performance, but has the disadvantages of high price and poor toxicity resistance; the other is a transition metal Ni, W Mainly, base metal hydrogenation catalysts with other additives have a high loading of active components, generally above 30%, and the catalyst is rarely recovered after deactivation, resulting in waste of resources, and the catalyst has harsh hydrogenation conditions Generally, the hydrogenation temperature is required to be greater than 250°C, and the hydrogenation pressure is greater than 15MPa
There are many safety hazards and high operation requirements in production.

Abstract

The invention discloses a nickel catalyst for C5 petroleum resin hydrogenation. The nickel catalyst comprises an activated carbon carrier, Ni nano-particles attached to the activated carbon carrier, and amorphous alloy nano-particles of Ni and a metal auxiliary agent, wherein the amorphous alloy nano-particles are attached to the activated carbon carrier. The weight percentage of Ni in the catalyst is 3%-8%, the weight percentage of the metal auxiliary agent is 0.1%-0.5%, and the metal auxiliary agent is zinc and / or cobalt. The invention also discloses a preparation method and application of the catalyst. The nickel catalyst disclosed by the invention has the advantages that the main active component nickel is modified by adding one or two of the auxiliary agent Zn and Co, so that nickel crystal lattices distort, deform and become thin, the areas of crystal faces are effectively enlarged, and the conversion rate and the selectivity of the catalyst are increased; in addition, due to the added metal additives, aggregation and enlargement of nickel crystal particles can be hindered, the stability of microscopic morphology of the catalyst is maintained, and the service life of the catalyst is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of nanometer metal catalyst preparation, in particular to a C 5 A nickel catalyst for petroleum resin hydrogenation, a preparation method and application thereof. Background technique [0002] C 5 Petroleum resin is a polymer with a relative molecular weight lower than 2000, which is a polymer with a relative molecular weight of less than 2000, which is obtained by cationic polymerization of the cracked carbon five fraction produced by the ethylene plant. Normal C 5 Petroleum resins usually have the defects of dark color, odor, low thermal oxygen stability, poor cohesive force and compatibility, mainly due to the high content of unsaturated bonds in the molecule. C 5 Hydrogenated petroleum resin is C 5 The modified product of petroleum resin belongs to high-grade special petroleum resin. In addition to the general purpose of ordinary petroleum resin, it is mainly used as light-colored road marking pain...
