Product introduction and performance
The regenerative high-temperature air combustion method (HTAC) is a new combustion technology with great energy-saving and environmental protection functions. The honeycomb ceramic regenerator,also known as ceramic regenerator and ceramic honeycomb, is a key components of regenerative burner,widely used in steel， machinery， building materials， petrochemical, non-ferrous metal smelting and other industries，such as push- type heating furnace，step-type heating furnace， heat treatment furnace，ladle/ tundish roaster， forging furnace, melting furnace，soaking furnace, radiant tube burner, hood furnace,blast furnace hot blast stove， oil and gas boiler; various ceramic kiln in building materials industry,various glass kiln; various tubular heating furnace,cracking furnace and other in petrochemical industry furnaces. The technology is to make two regenerative alternating heat absorption exotherms through the reversing device，to recover the heat of the flue gas to the maximum limit, and then to heat the combustion air and gas in the furnace to above 1000 C，it can achieve stable ignition and efficient combustion even the low calorific value of the inferior combustion， saving fuel up to 40-70 °C. The output will be increased by more than 15 °C， the oxidation loss of the steel embryo will be reduced by more than 40%，the NO2 emission will be less than 100 pm，and the exhaust gas temperature will be lower than 150″C， which greatly reduces the greenhouse effect of the earth’ s atmosphere. If most of industrial furnaces in the country adopt HTAC technology, its economic and social benefits are immeasurable，which will greatly alleviate the shortage of energy and improve the living environment of human beings. Since its launch in the market， it has achieved good results and is favored by the steel smelting industry.

Desorption
The material itself is non-flammable and can be used safely at an ambient temperature of 600°C. The hydrophobic product has a high-quality desorption function. The desorption can be achieved at a temperature of 300°C. The desorption time is short, the desorption is complete, and there is no secondary generation. Pollution is the best material to replace honeycomb activated carbon. It can be desorbed at high temperature and completely desorbed. It is suitable for: coating, printing, chemical, pharmaceutical, electronics, injection molding, petroleum, smelting and other industries. The product size can be customized according to customer needs.
Adsorption method

3.Adsorbed VOCS concentration range 1-1000mg/m³
4.Corresponding VOCS types: alcohols, ethers, esters and benzenes
Zeolite is a hydrophobic zeolite, which can be used in a certain humidity environment. The recommended humidity range is less than or equal to 80%.
5.The best performance after adsorption and desorption
Desorption method
1.The desorbed gas is 10-20% of the adsorbed gas, and the space velocity is 400-1000-1
2.The desorption temperature should be based on the gas properties, generally from 240°C to 300°C for continuous heating (5°C per minute, this parameter needs to be adjusted according to the type of exhaust gas) The desorption time is about 30 minutes, depending on the degree of completion of the desorption. , it takes a long time to reach 100% desorption.
3.After desorption, it was cooled to room temperature and then adsorbed.
