Product Description

RN-302 ammonia selective reduction NOx removal (SCR method) catalyst
Rn-302 Ammonia Selective Reduction Nox Removal (SCR method) Catalyst

Product Introduction
The AN-302 catalyst uses hydrogen as a reducing agent to selectively reduce and eliminate nitric acid and nitrate tail gas, and it can convert NOx into N2 and H20. It is suitable for NOx in medium-pressure or pressurized nitric acid-based final industrial smoke, and has the characteristics of fast start-up at medium temperature and high denitrification efficiency.

Working principle:
6NO+4NH3→5N2+6H20    -1807.0KJ/MO1
6NO2+8NH3→7N2+12H20 -2659.9KJ/MO1

Catalyst loading and activation start-up
The catalyst does not need hydrogen reduction before use. During system start-up, the exhaust gas pressure is gradually increased according to the resistance of the exhaust gas treatment system. After   the system is stable, the ammonia flow rate is adjusted according to the NO 2 content in the exhaust gas, so that the NH3x ratio is controlled at 1.1~1.2. The start-up temperature of this catalyst is 200~220°C, generally 220~380C can meet the requirement of eliminating NOx.

Catalyst bed pressure con trol
The catalyst bed pressure of industrial devices is closely related to the ratio of catalyst bed height to diameter (generally 0.3~0.5), gas flflow rate, gas distribution plate opening ratio, catalyst particle shape, particle size, mechanical strength and operating process conditions. It is recommended that the height-to-diameter ratio of the catalyst bed be controlled at about 0.4, which can effectively control the pressure drop of the catalyst bed at 0.1~0.15kg/cm2. General chemical design units require that the catalyst bed pressure drop be ≤0.3kg/cm2.
