LanteComb Honeycomb
The LANTECOMB honeycomb ceramic series product is another patented product developed by our company after MLM structured packing (patent number: 200720126497.7). It perfectly combines the structure of honeycomb ceramic and MLM structured packing, which increases the porosity of the product and reduces the pressure of the product. At the same time, due to the improvement of the structure, the "node" of heat transfer is avoided; in addition, LANTECOMB turns the original independent square hole into a connected rectangular hole, which is conducive to the distribution of gas and improves the heat transfer efficiency and exhaust gas purification rate. . After the test of our company's RTO experimental device, the pressure drop is equivalent to that of the MLM series, and its thermal efficiency can reach more than 97%, which greatly improves the heat storage performance of the product and reduces energy consumption, and is widely welcomed by domestic and foreign users. At present, the product can be divided into two series, LanteComb L and LanteComb H, according to the specific surface area.

2. Catalyst carrier
2. Catalyst carrier
Cordierite ceramic materials are widely used in the production of honeycomb ceramic catalyst carriers because of their low thermal expansion coefficient, high specific surface area, low pressure, rapid light-off time and good pore density.
The cordierite honeycomb ceramic has a honeycomb structure with thousands of parallel channels to pass the exhaust gas into the turbulent device, so that the exhaust gas and the precious metal are fully contacted, the mass transfer conditions are improved, the conversion efficiency is improved, and the honeycomb ceramic becomes an oxidation reaction and Ideal catalyst support for reduction reactions.
