VOCs Removal Honeycomb Ceramic Catalyst

Organic waste gas is a common pollutant discharged by petrochemical, light industry, plastics, printing, coating, spray painting and other industries, Exhaust gas often contains hydrocarbons and oxygen-containing organic compounds, if these gases are no treated, and discharged into the atmosphere directly ,they will cause serious pollution to the environment, also endanger human health.

CAS-KR-V01 type VOC Removal Honeycomb Ceramic Catalyst was prepared by using cordierite honeycomb ceramics as support, special coating materials and noble metals Pd and Pt as active groups, it has high catalytic activity, good thermal stability, long service life, small airflow resistance, high strength and so on, the waste gas purification catalyst can be widely used in chemical industry, paint, enameled wire, coating, oven and other industries of organic waste gas treatment.

VOCs organic waste gas purification treatment generally adopts low temperature catalytic combustion method, the low temperature catalytic combustion treatment method is to treat the organic matter in the tail gas at low temperature, high efficiency, energy saving and environmental protection with the help of catalyst catalysis, so as to achieve the purpose of emission standards, catalytic combustion reaction is a typical gas-solid phase catalytic reaction, its essence is at a certain temperature, a process of the organic matter (VOCs) adsorbed on the surface of the catalyst and oxygen from the air are catalyzed to complete oxidation into harmless CO2 and H2O, and releasing reaction heat, with the help of catalyst, the ignition temperature of organic matter can be greatly reduced, flameless combustion can be carried out, and preheating energy consumption and NOx generation can be reduced. The typical reaction equation is as follows:

The simple VOCs organic waste gas purification process is shown in the following figure

According to the flow chart, the total content of organic matter in the high concentration organic waste gas is generally about 1000mg/m3-10000mg/m3 (if the concentration is too high, dilute it with air),the system includes pre-heating, heat exchange, catalysis, PLC automatic control module, etc, after the produced waste gas is collected in a organized way, it is inhaled into the heat exchanger in the purification system, after heat exchange preheating, it is inhaled into the heating chamber for supplementary heating (stop heating when the ignition temperature is reached),then the waste gas reaching the ignition temperature is inhaled into the catalytic bed, catalytic oxidation flameless combustion occurs, the combustion efficiency can usually reach more than 99%, can fully meet the emission standards, after purification, the high temperature flue gas preheats the inlet exhaust gas to the ignition temperature through heat exchange to maintain the system running without heating power. After purification, the high temperature flue gas preheats the inlet exhaust gas to the ignition temperature through heat exchange to maintain the system running without heating power, If the temperature of the flue gas after preheating the waste gas is high, it can also be used to heat the fresh air or water and produce water vapor, etc., so as to achieve the reuse of heat energy and reduce waste gas treatment and production energy consumption..

① Low light-off temperature, It can self-sustaining operation when reach a certain concentration without external energy supply ,save energy.

② Low combustion temperature, flameless combustion, no NOx compounds produced.

③ fast burning rate, burning completely, no benzo pyrene, dioxin, a highly toxic and carcinogenic substance produced

④ The combustion products are harmless CO2 and H2O, no secondary pollutants such as solid waste, sewage, waste solvent and waste gas.

⑤ The treatment efficiency is very high, and the complete compliance rate of one treatment is much higher than that of other treatment methods

⑥The process equipment is simple, the technology is mature, the equipment and the maintenance cost is low, the unit cost of waste gas treatment is low

⑦Reasonably designed equipment, safe and reliable operation, stable performance, PLC automatic operation, no need for special maintenance

⑧Wide range of application, suitable for high ,medium, low concentration, all kinds of complex odorous gas treatment in different industries.

⑨Compact structure, small occupation area

Precautions: At low temperature, a large amount of organic matter go into the catalytic bed, resulting in the catalyst "stuffy", resulting in temporary inactivation; sulfur, phosphorus, arsenic containing compounds, halogen compounds, heavy metal compounds will react with the active ingredients, resulting in permanent catalyst deactivation; Dust, carbon deposition, and high boiling viscosity materials attach to the surface of the catalyst, covering the active site of the catalyst, resulting in loss of catalysis; high temperature can make the catalyst carrier and active components agglomerate or sinter, resulting in a significant reduction in the number of active sites, and eventually inactivation

Maintenance measures: low temperature "smother": before normal operation , the catalytic bed should be preheated in the fresh air to get the reaction temperature, then introduce into the organic waste gas; toxic substances such as sulfur exist, such substances can be removed by means of pre-treatment or select a catalyst with corresponding resistance, dust, carbon deposition, and high boiling viscosity materials: do a good job of dust removal and other pre-treatment; over temperature: When the temperature of the catalytic bed exceeds 600°C, stop the system running or use fresh air to dilute and cool.
