Hydrogenation and deoxidization method for palladium ion type catalytic resin

Abstract

The invention discloses a hydrogenation and deoxidization method for palladium ion type catalytic resin, which comprises dissolving palladium chloride in distilled water, agitating homogeneously, passing palladium chloride solution through contacting tower containing strong acid type cationic ion-exchange resin, rinsing with water, drying at room temperature, letting hydrogen gas into resin for reduction, letting water with dissolved oxygen from the top of the packed column, sprinkling onto the whole cross-section homogeneously through a liquid distribution apparatus, lifting the water with dissolved hydrogen gas with a pump, injecting into a contacting tower incorporating palladium ion type catalytic resin, and passing water through palladium ion type catalytic resin.

Description

[0001] Technology area

[0002] The invention belongs to a water treatment method, in particular to a palladium ion-type catalytic resin hydrogenation and deoxygenation process. Background technique

[0003] Under normal temperature and pressure, a certain amount of oxygen (dissolved oxygen) will dissolve in water, and its concentration is generally 8-10mg / L. For drinking water, the higher the concentration of dissolved oxygen in water, the better the water quality, but for many industries In terms of water, high concentrations of dissolved oxygen can cause corrosion of equipment or degradation of product quality. For example, the presence of dissolved oxygen in boiler feed water will aggravate the corrosion of the system, thereby shortening the service life of pipelines and equipment. Therefore, in the "Water Quality Standard for Low-Pressure Boilers" (GB1576-96), it is required that steam boilers with evaporation greater than 6t / h and Hot water boilers with a rated power ≥ ...
