SINOKLE Silica-Alumina Ozone Catalyst KHC-F2001: Comprehensive Evaluation and Applications

SINOKLE silica-alumina-based ozone catalyst KHC-F2001 comprehensive evaluation and engineering

As a specialized-innovative high-tech environmental protection enterprise, SINOKLE has been deeply engaged in industrial wastewater advanced oxidation and oil-water separation for many years,and has independently developed the KHC-F2001 silica-alumina-based ozone catalyst. Using a silica-alumina composite oxide as the carrier and loading multiple metal active components, it has outstanding chemical stability and catalytic activity,and can be packaged with the company's atmospheric and vacuum electric-desalting pure physical oil removal skid device,CDOFand integrated ozone oxidation equipment as a complete package, building a complete wastewater treatment process chain of 'front-endCDFUcyclonic dissolved-air flotation pretreatment + silica-alumina ozone catalytic deep oxidation', suited to various high-salinity, extreme acid-base, high-concentration refractory industrial wastewater treatment scenarios, and is the preferred catalytic media in the ozone catalytic oxidation system for harsh water quality conditions.

Product Catalytic Mechanism and Core Performance Indicators

(1) Catalytic Mechanism

KHC-F2001 uses a sol-gel composite sintering process to prepare the silica-alumina substrate, constructing a large number of Lewis and Bronsted dual-acidic active sites on the carrier surface and loading composite catalytic components of manganese, iron, cobalt, etc. The catalyst efficiently catalyzes ozone decomposition, quickly generating strongly oxidizing hydroxyl radicals, breaking the stable chemical bonds of macromolecular organic pollutants, directly mineralizing refractory substances such as humus, antibiotics, halogenated hydrocarbons and dye intermediates into carbon dioxide and water, effectively reducing wastewater COD, color and biological toxicity, simultaneously improving water biodegradability, and greatly reducing the load on back-end biochemical and membrane treatment units.

(2) Key Technical Indicators

KHC-F2001 Silica-Alumina Ozone Catalyst Eight Core Advantages

Excellent catalytic activity, greatly improved ozone utilization efficiency
Synergistic catalysis of multiple metal active components achieves ozone decomposition and conversion efficiency above 95%. At the same treatment effluent standard, ozone dosage is significantly reduced, lowering ozone generator capacity and electricity consumption and reducing long-term operating energy cost. For high-color and high-COD wastewater, decolorization and organic degradation effects are outstanding, with color removal rate up to 98%.

Extremely strong chemical stability, broad-spectrum tolerance to harsh water quality
The silica-alumina oxide carrier is itself acid-base and high-temperature resistant, with a pH adaptation range covering 2-12. Facing high-salinity, strongly acidic and strongly alkaline wastewater, it can operate stably long-term, with no precipitation or loss of active components, causing no water heavy-metal secondary pollution, suited to projects with harsh water conditions such as landfill leachate, pharmaceuticals and coking.

High mechanical strength, resistant to high-velocity water scouring and wear
Particle forming undergoes high-temperature sintering and curing. Single-particle compressive strength exceeds 120 N, and it is not easily broken or pulverized under equipment air-water backwashing and high-velocity hydraulic impact, with extremely low media loss, greatly reducing daily catalyst replenishment and replacement workload.

Anti-clogging and anti-fouling, suited to continuous industrial production
Using a proprietary micropore forming paired with surface hydrophilic modification process, suspended solids and high-molecular organic matter in water do not easily adhere and clog internal pores, requiring no frequent shutdown disassembly and cleaning, fully matching the 24-hour uninterrupted continuous water treatment operation mode of refining and chemical enterprises.

Ultra-long service life, reducing media replacement and hazardous waste cost
Under conventional industrial conditions, service life reaches 5-8 years, far exceeding ordinary industry catalytic media; after activity decay, the media can be restored to catalytic performance through a simple regeneration process, greatly extending the overall media replacement cycle, reducing hazardous waste generation and disposal expenditure, with significant whole life-cycle comprehensive operation and maintenance cost advantage.

Broad-spectrum pollutant degradation, suitable for multiple types of refractory wastewater
The abundant dual-acidic active sites have efficient oxidative decomposition capability for various toxic refractory pollutants such as phenols, antibiotics, halogenated organic matter, humic acid and dye macromolecules. They can be used both for wastewater deep upgrading and for pretreatment of highly toxic wastewater, improving water biochemical performance.

Strong compatibility with complete equipment, can be linked with SINOKLE pretreatment process
It can be used with the company's high-efficiency coalescence oil remover,CDFUand cyclonic dissolved-air flotation equipment in synergy. The front-end pure physical process removes floating oil, emulsified oil and suspended impurities, and the back-end KHC-F2001 ozone catalytic unit deeply degrades dissolved organic pollutants, solving the dual pain points of oily chemical wastewater oil exceedance and refractory COD in one stop.

Green operation, reducing chemical agents and secondary pollution
The entire ozone catalytic process requires no large dosing of flocculants and decolorization agents, greatly reducing chemical sludge production; the silica-alumina-based carrier is stable, with no soluble heavy-metal leaching, meeting the green low-carbon and clean production environmental control requirements of chemical and petrochemical industries.
