Industrial SCR honeycomb catalyst

The SCR honeycomb catalyst is formed by homogeneous one-time extrusion and has a high specific surface area; Flat plate catalysts are based on stainless steel grids and coated with active materials, which have high resistance to fly ash wear and low pressure loss, and strong resistance to arsenic poisoning; The corrugated plate catalyst is made of reinforced glass fiber as the substrate, impregnated with active materials, with small mass, high activity, and strong resistance to CaO poisoning. In principle, different types of catalysts can meet the performance requirements of specific projects. However, the activity, pitch, effective specific surface area, catalyst volume, and resistance of different types of catalysts are not the same. Therefore, a catalyst form and layout can be selected through comparison to improve the cost-effectiveness of the project and effectively reduce the initial construction and operation costs of the project.

The SCR honeycomb catalyst has excellent low-temperature activity, thermal shock resistance, and poisoning resistance, while also having a high specific surface area. Excellent material properties can greatly shorten the heating time of the catalyst, enabling rapid heating to the catalyst's ignition temperature and SCR reaction. At high NOx concentrations and space velocities, the removal efficiency of NOx remains high while maintaining a low ammonia escape rate. Reasonably design the external dimensions and pore density of the catalyst according to application requirements and exhaust conditions to ensure the utilization rate of the catalyst.

Industrial SCR honeycomb catalystIt is a flue gas treatment process that has both good environmental and economic benefits. Its characteristics of low temperature, low dust, low poisoning, low cost, and high service life cannot be achieved by medium temperature catalysts, which is in line with our expectation of pursuing low input and low consumption while pursuing environmental benefits. Therefore, it is not difficult to see that the low-temperature SCR process is a flue gas purification process worth developing and will also be the trend of SCR process development.

Industrial SCR honeycomb catalystHoneycomb catalysts are generally homogeneous catalysts. A mixture of TiO2, V2O5, WO3, and other materials is extruded through a ceramic extrusion device to produce catalyst elements with a cross-section of 150mmX150mm and varying lengths, which are then assembled into catalyst elements with a cross-section of approximately 2m; A standard module of 1m.
