Inside the Carbon-Based Ozone Catalyst KHC-F1001: What 1,400 m²/g Surface Area and a 90% Ozone Decomposition Rate Really Mean
Selecting a catalyst is essentially about reading the engineering language behind the parameters. The carbon-based ozone catalyst from SINOKLE KHC-F1001 is a case in point: its parameter set deserves to be taken apart item by item.
1. 1,400 m²/g specific surface area: an order-of-magnitude advantage in active sites
Specific surface area determines how many reaction sites a catalyst can offer.KHC-F1001 uses a high-grade activated carbon carrier with an iodine number above 1,100 mg/g and a specific surface area of 1,400 m²/g, far beyond the level of conventional carbon-based catalysts. The huge number of active sites greatly improves the contact efficiency between ozone and organics, and the well-developed pore structure also adsorbs and traps trace organic pollutants, forming an “adsorption + catalysis” dual mechanism whose oxidation performance is clearly superior to ordinary catalysts.
2. 90% ozone decomposition rate: a direct expression of ozone utilisation
The higher the decomposition rate, the more efficiently the catalyst converts ozone into reactive species.A 90% ozone decomposition rate means the ozone dosage can be reduced significantly and equipment energy consumption falls accordingly. Combined with an improvement in organic degradation capacity of more than 10 times, KHC-F1001 turns “less ozone, more COD removal” from an ideal into reality.
3. 70% COD removal and 95% colour removal: quantifiable results
A COD removal rate of 70% and a colour removal rate of 95% are stable indicators for advanced oxidation of refractory wastewater. The catalyst accelerates ozone decomposition and rapidly generates hydroxyl radicals, mineralising large refractory organic molecules into carbon dioxide and water while simultaneously cutting COD, colour and toxic organic pollutants and improving biodegradability, easing the load on downstream biological treatment and reuse stages.
4. 95% strength and a 3–5 year service life: the confidence behind long-term operation
Mechanical strength of 95%, with abrasion and erosion resistance and a very low breakage rate under long-term fluidisation and backwashing; a pH operating range of 3–11, with resistance to acid, alkali and high temperature for stable operation in a wide range of chemical environments; and a service life of 3–5 years, above the 2–3 years common in the industry, with simple regeneration restoring activity after deactivation and greatly reducing packing replacement frequency and cost.
5. Applications and system integration
KHC-F1001 is widely used in advanced wastewater treatment, municipal water treatment and circulating water treatment, covering oil-bearing wastewater from petroleum refining, landfill leachate, pharmaceutical wastewater, dyeing wastewater, coal chemical wastewater and other demanding applications. In the refining industry it can be combined with purely physical desalter de-oiling to form a full “front-end coalescing flotation de-oiling + back-end carbon-based ozone advanced oxidation” flowsheet, and it can also be matched with CDFU cyclonic dissolved gas flotation and CDOF ozone oxidation equipment packages, adapting to skid-mounted integrated units with shorter residence time and a smaller footprint.
Putting the parameters together, the engineering profile of KHC-F1001 is clear: a high-surface-area carbon carrier, high catalytic activity at its core, super-hydrophilic modification to secure mass transfer efficiency, high stability for long-cycle operation, easy regeneration to lower whole-life cost, and green chemistry to answer compliance requirements. These six dimensions reinforce one another, forming a complete value loop of efficiency, durability, economy and environmental performance. For engineers currently evaluating ozone catalytic oxidation options, this parameter system provides a clear benchmark for side-by-side comparison.
It is worth stressing that catalyst selection is never about a single indicator. A high surface area means more active sites, but strength, service life and hydrophilicity must also underpin performance before laboratory advantages become engineering advantages. From carrier selection to active-component loading and further to surface hydrophilic modification, every step at KHC-F1001 works together to deliver the stable results of 90% ozone decomposition, 70% COD removal and 95% colour removal.
At the level of complete systems, KHC-F1001 combined with SINOKLE CDFU cyclonic dissolved gas flotation and CDOF ozone oxidation equipment forms a complete ozone catalytic oxidation unit capable of automated operation and skid-mounted integrated deployment, offering one-stop advanced treatment equipment for new projects and capacity upgrades.
In addition, the product is supplied as black granules or extruded cylinders, with customisable sizing of 3–5 mm, a bulk density of 0.45–0.55 g/cm³ and a moisture content of 5%, making loading and backwashing convenient and the engineering implementation straightforward.
