The development of new, high-efficiency catalysts is the basis for the leapfrog development of the petroleum and chemical industries. In recent years, nearly 50% of the international research on catalysis has been focused on the development of new catalysts, and increasing attention has been paid to them.

The main function of catalysts is to reduce the activation energy of chemical reactions and speed up the reaction rate, so they are widely used in oil refining, chemical, pharmaceutical and environmental protection industries. Technological advances in catalysts are one of the most effective driving

In recent years, hydrogenation petroleum resin has become more and more popular, and XunKai Catalyst has been devoted to research for many years. In previous issues, we have introduced the application of resin, hydrogenation process and hydrogenation catalyst, and today we will talk about what we know and don't know about catalyst poisoning in hydrogenation process.

High efficiency desulfurization catalyst in natural rubber, together with sulfur yellow, can prevent vulcanization reversion, improve heat resistance, reduce heat generation, aging resistance, improve rubber and cord adhesion and vulcanization rubber modulus. It is used in the rubber of shoulder rubber and cushion layer of load tires, which can solve the problem of shoulder hollow of slant load tires, and also can be used in the large-size thick products of natural rubber and various rubber miscellaneous products.

Nanotechnology will make human development and use of technology after the material-led, energy-led and information-led, is happening in a new era of mutual integration of the three on the basis of biotechnology and mutual integration at the nano level as the dominant.

Catalysis is a typical example of early empirical reliance on nanotechnology development. Nanoscale catalysts have many superior conditions due to the small size of nanoparticles, the large volume percent occupied by the surface, the different bonding and electronic states on the surface compared to the interior of the particles, and the incomplete number of atomic coordination on the surface.
