Abstract

The invention relates to a method for hydrogenation of C5 petroleum resin. A fixed bed reactor is adopted. The catalyst includes a carrier and an active component. The carrier is an alumina-silicon oxide composite carrier. The active component includes nickel oxide, molybdenum oxide and magnesium oxide. In terms of mass percentage, the content of alumina-silica composite carrier in the catalyst is 70-90wt%, the content of active component nickel oxide is 3-20wt%, the content of molybdenum oxide is 2-18wt%, and the content of magnesium oxide is 0.1-20wt%. 6.5 wt%. Reaction process conditions: reaction temperature 150-300°C, reaction pressure 4-10MPa, volumetric space velocity 1.0-6.5h ‑1 , the volume ratio of hydrogen to oil is 40-400. The catalyst C5 petroleum resin has high hydrogenation activity, strong sulfur resistance, light color and good thermal stability of the resin product.

Description

technical field [0001] The invention relates to a method for hydrogenating C5 petroleum resin. Background technique [0002] Petroleum resin is a product obtained by polymerization of the by-product carbon five or carbon nine fractions during cracking to produce ethylene through a complex catalyst or by thermal polymerization. Its molecular weight is generally less than 2000, the softening point is 5-150°C, and it is thermoplastic viscous liquid or solid. Petroleum resin has tackifying properties, adhesiveness and compatibility with other resin products, so it is often mixed with other polymer materials to improve the performance of various products, which are mainly used in coatings, adhesives and inks and other fields . However, with the continuous development of technology, the requirements for the quality of petroleum resin (hue, softening point, etc.) are getting higher and higher. C5 petroleum resin raw materials are complex in composition (often with more chromogen...
