VOCS catalyst

VOCS catalystsupply

According to the definition of the Union of Pure and Applied Chemistry (IUPAC) in 1981, a catalyst is a substance that changes the reaction rate without altering the total standard Gibbs free energy of the reaction. Catalysts can accelerate chemical reaction rates and alter chemical reaction pathways. The effect of a catalyst in a chemical reaction is called catalytic action.

VOCs are also the main substances involved in atmospheric photochemical reactions, generating PM2.5 and ozone, which are the main substances causing a decline in air quality. The impact on the human body includes damage to nerves, lungs, kidneys, blood, liver, and metabolism.

Reaction space velocity refers to the amount of gas processed by a catalyst per unit time and volume under specified conditions, measured in m3/(m3 catalyst · h), i.e. h-1. The airspeed reflects the processing capacity of the catalyst.

For precious metal catalysts, volumetric air velocity is given as the ratio of raw material volumetric flow rate (Nm3 · h-1) to catalyst volume (m3).

The contact time of the catalyst is the time that the reaction gas stays in the catalyst bed, that is, the reaction time. Contact time (s)=3600/airspeed.

VOCS catalystPrepared with precious metals Pd and Pt as active components; It has the characteristics of high catalytic activity, good thermal stability, long service life, low airflow resistance, and high strength.

Catalysts can be widely used in the treatment of organic waste gases in industries such as chemical engineering, painting, enameled wire, coating, and baking ovens. The catalytic oxidation (catalytic incineration) system uses precious metal platinum and palladium catalysts to catalyze the incineration (or reduction) of volatile organic compounds or nitrogen oxides in the exhaust gas at 250-600 ℃, converting the organic compounds or nitrogen oxides into carbon dioxide, hydrogen chloride, nitrogen dioxide, sulfur dioxide, water, and nitrogen.
