Industrial VOCs catalyst

An environmentally friendly material that decomposes volatile organic compounds (VOCs) through catalytic oxidation, primarily used for organic waste gas treatment in fields such as painting, printing, and chemical engineering. It utilizes cordierite ceramic honeycomb as the primary carrier, γ-Al2O3 as the secondary carrier, and employs active components such as precious metals Pd and Pt, achieving a purification efficiency of over 97% within the temperature range of 220℃~750℃.

Gasoline and natural gas （ICE）pd-pt-rh catalyst

The carrier component of a three-way catalyst is a porous ceramic material installed in a specially designed exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but rather becomes a catalyst after being coated with a layer of precious metals such as platinum, rhodium, and palladium, as well as rare earth coatings. The exhaust system layout is designed according to the catalyst of different sizes in combination with the car chassis. After being enclosed in a metal shell and shockproof layer, it becomes a catalytic converter.

Catalyst using metal honeycomb as a carrier

The metal honeycomb series products are widely used in industries such as aviation, aerospace, power, transportation, electronics, textiles, and construction.Honeycomb materials include copper, aluminum alloys, titanium alloys, stainless steel, high-temperature alloys (Haynes214, Hastelloy X, etc.), and other materials

According to various sizes and types of catalyst coatings. Can be applied to: gasoline vehicle three-way catalyst, diesel vehicle DOC, ASC, landscaping equipment (general machinery), motorcycle three-way catalyst, power generation equipment, diesel generators, oil and gas pump stations, and aviation filtration

Diesel engine exhaust catalyst

The exhaust after treatment device is a key mechanical component used in diesel vehicles and other internal combustion engine equipment to purify exhaust gas, achieving pollutant reduction through catalytic conversion, particle capture and other technologies. The device includes core components such as diesel oxidation catalyst (DOC cordierite/metal), particulate filter (DPF cordierite/silicon carbide), selective catalytic reduction (SCR copper c/Cu/vanadium V/iron Fe), ammonia escape (ASC), etc. Various components work together to treat harmful substances such as nitrogen oxides and particulate matter through different mechanisms
