          Catalyst external repair technology

          Release time:2017-04-11 09:59:10    source:

          Catalysts are widely used in the chemical and chemical industry, to improve the rate of material reaction, but its nature does not change a medium, usually the majority of solid catalyst. Solid catalyst has a certain life, according to the use of the catalyst effect, the catalyst life can be divided into three stages:
          1, the first stage for the initial life, the industry is defined as fresh catalyst.
              The fresh catalyst is produced by a series of physical methods such as kneading, extruding or kneading, dipping or spilling, baking and the like by the carrier and the active ingredient, all of which are present in the form of a metal oxide Stable nature, non-toxic non-combustible.
              The catalyst carrier is generally composed of a mixture of silicon, aluminum and zinc, or a mixture of a plurality of oxides, which is made into a certain shape by a kneading, extruding or kneading or baking molding, baking and the like, and has a pore structure The substance has no or less activity and is primarily used to carry the active ingredient.
              The active ingredient refers to a substance that provides activity for the catalyst and is a major component that provides catalytic action in the chemical reaction. The oxides of metals such as molybdenum, tungsten, nickel, cobalt, tungsten, palladium, and platinum are generally supported by one or more combinations, such as impregnated or sprayed, by physical means such as those provided in the catalyst carrier to make.
          2, the second stage for the mid-life, the industry is defined as the catalyst to be repaired (renewable)
              The catalyst surface and the pores are reduced in activity due to carbon deposition or colloidal coverage and clogging after a period of time (typically 2 to 3 years) to be regenerated (repaired) with the catalyst as a fresh catalyst, resulting in an increase in energy consumption or Affect product quality. At this point, the catalyst still has a value that requires a minor repair (regeneration) that does not disrupt the structure to restore activity and continue to be used in situ.
              The catalyst and active ingredient of the catalyst to be regenerated (modified) did not change compared with the fresh catalyst, but increased the deposition of sulfur and carbon. The purpose of repairing (regeneration) was to eliminate the sulfur and restore the original pore distribution of the catalyst. Disperse the active ingredient (regenerated), so that the catalyst activity is restored as new.
              The company has a full set of repair technology, can provide users with full-service.
