EG Dilute Nitric Acid Wastewater Treatment 

Process and catalyst

EG dilute nitric acid wastewater treatment process and catalyst


  1. Application


RK-21 dilute hydrogen nitrate reduction catalyst is developed and manufactured by Dalian Reak Science & Technology Co., Ltd, which is exclusively used for hydrogen nitrate reduction process of effluent of EG manufacturing process.

 

  2. Catalyst physical properties


RK-21 Dilute hydrogen nitrate reduction composition:

Special carrier, Precious metal

Appearance: small black particle

Size: 3-8mm

Bulk density: 0.8±0.2 Kg/L

Crushing strength (Average value): ≥40 N/particle

 

  3. Reaction principle


Principle reaction equation:

HNO3+2NO+3CH3OH = 3CH3ONO+2H2O

 

  High catalyst selectivity, No nitrocarbol and other by-products that impact EG main process generated in process of catalyst using
