Abstract
The invention discloses a metal loss resistant carbon five petroleum resin hydrogenation catalyst, which is prepared from Pt group active metal and beta-Mg 2 V 2 O 7 /SiO 2 The composite carrier and the auxiliary agent boron. The catalyst can improve the catalytic efficiency of the hydrocarbon-modified petroleum resin and ensure that the active metal is not easy to lose.
Description
Technical Field
The invention particularly relates to a metal loss resistant carbon five petroleum resin hydrogenation catalyst.
Background
The main chain of the carbon five petroleum resin is an aliphatic structure, and has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance, chemical corrosion resistance and the like. However, the carbon-five petroleum resin has the defects of high brittleness, dark color, odor, lack of polar groups on the structure and the like due to unsaturated chemical bonds. Unsaturated carbon-carbon double bonds in the resin are subjected to hydrogenation saturation in a catalytic hydrogenation mode, so that the unsaturation degree of the resin can be reduced, and the performances of the resin such as stability, oxidation resistance and the like are improved. The hydrogenated carbon five petroleum resin is colorless, tasteless, high in light oxygen stability, and is an upgrade of common yellow resin additives used in specific fields, especially furniture binder, printing ink, high-grade paper, paint and other fields. With the requirement of human on health and environmental protection, the hydrogenated carbon five resin gradually replaces the carbon five petroleum resin to produce energy, and the hydrogenated carbon five petroleum resin can be applied to more fields.
C5 petroleum resin hydrogenation catalysts are mainly classified into Ni-based catalysts and noble metal-based catalysts, and although Ni-based catalysts have a cost advantage to facilitate industrialization, their activities are relatively low and require high reaction temperatures. In view of the above problems, the use of noble metal-based catalysts in the hydrogenation of hydrocarbon-modified petroleum resins has been increasing in recent years. The noble metal catalyst has higher hydrogenation performance and milder reaction conditions, but the noble metal has poorer dispersibility on the carrier, and chlorine element in resin often causes the loss of active metal in the hydrogenation catalyst. The patent CN 104525198B improves the catalytic activity of the catalyst by adding Ag or VB group elements, and simultaneously has better resistance to the toxicity of impurities such as sulfur, halogen, nitrogen and the like, thereby having longer service life. CN 106268725A uses gamma-alumina as carrier and adopts step-by-step method to load palladium, molybdenum, manganese and other metals, so that the catalyst has better hydrogenation activity. CN 102935367B provides a C5 petroleum resin hydrogenation catalyst, which comprises an alumina-titanium oxide composite carrier, metal palladium loaded on the composite carrier, and auxiliary agents of molybdenum and tungsten, and the catalyst has not only lower hydrogenation activity but also better impurity resistance and good stability when being used in a C5 petroleum resin hydrogenation process.
