▌Product Overview
The HZY-CH series catalyst is a specialized ozone catalyst developed by HZY to address issues such as poor mass transfer efficiency, low ozone utilization rate, and high investment and operational costs in traditional ozonation technology. This catalyst utilizes silicon, aluminum, and titanium as carriers and various rare earth metal oxides and transition metal oxides as catalytic components. It is refined through processes including carrier doping, extrusion molding, mixed impregnation, low-temperature drying, and high-temperature calcination. This process enhances the production of •OH, significantly boosts ozonation capacity, and features high catalytic activity and long service life. It is an ideal catalyst for ozonation catalytic oxidation.
▌Product advantages
(1) Composite porous high-strength silica-alumina-titanium catalytic carrier, high-temperature melt-supported catalyst components, enhancing the stability of the catalyst. High mechanical strength, no loss, no need for regular addition.
(2) Multiple catalyst components enhance the adaptability of the catalyst to different wastewaters while improving its catalytic activity.
(3) Transition metals, rare earth metals, and oxidized metals are used as effective catalyst components to ensure sustained and high ozonation efficiency.
(4) It can significantly enhance the reaction rate between ozone and pollutants, effectively reducing treatment costs.
(5) It can catalyze the self-decomposition of ozone in water, increase the concentration of •OH generated in water, thereby enhancing the ozonation effect, and the decomposition efficiency is 2 to 4 times higher than direct ozonation.
(6) It can reduce the reaction activation energy or alter the reaction pathway, thereby achieving the goal of deep oxidation and maximizing the removal of organic pollutants.
▌Product Parameters
▌calculation formula
The porosity of the ozone catalyst is estimated at 50%;
If the hydraulic retention time (HRT) in static testing is 0.5 hours, the dynamic HRT in engineering practice is 1.0 hour; once the HRT is determined, the volume of ozone catalyst is also determined, which is calculated as water volume × dynamic HRT;
Example: For a water volume of 100m³/h and a dynamic hydraulic retention time of 30 minutes, the required amount of ozone catalyst is:
100×0.5=50 cubic meters. If converted to weight, it is 50×0.8 (loose density) = 40 tons
Note: You can consult the customer manager for assistance in accounting.
▌Comparison of catalyst performance
From the perspective of the combination of effective components and carriers:
Ceramsite/clay carrier: physical bonding, poor physical strength, easy loss of catalyst, short lifespan;
l Activated carbon carrier: Due to the binding of physical bonds, the catalyst is prone to loss, resulting in a short lifespan. The columnar shape increases the backwash head pressure;
Alumina carrier: chemically bonded, non-leachable, long-lived, highly resistant to contamination under neutral conditions, and stable in performance;
l Silica-alumina composite material carrier: It is an upgraded version of alumina carrier catalyst. Silica (which is itself a molecular sieve) enhances physical strength, providing higher hardness and lower wear.
