Diesel Oxidation Catalysts (DOC) is one of the most reliable ways to reduce pollutants of diesel particulate emissions. DOC technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles.
Our Diesel Oxidation Catalysts (DOC) is made of cordierite material, which is raw material molding and synthesized cordierite after burning. DOCâ??s channels are unimpeded, the exhaust gas can flow it smoothly, then HC, CO, PM are oxidized rapidly under the catalyst (precious metal), noxious emission are reduced effectively and reach emission standard.

Magnesium oxide, often referred to as magnesia, is a white, odorless, and alkaline solid with the chemical formula MgO. It is recognized for its diverse applications across industries. In healthcare, it is used as an antacid to relieve heartburn and indigestion, as well as a magnesium supplement. In the construction sector, magnesium oxide is utilized as a refractory material in kiln linings and as a fireproofing agent in building materials. It also plays a role in metallurgy as a refractory lining material for furnaces. Additionally, magnesium oxide finds application in the production of electrical insulators, as a catalyst in chemical processes, and as a stabilizer in some food products. Its ability to withstand high temperatures, neutralize acidity, and serve various functions highlights its importance in different industrial and consumer applications.
Take the sulfur and burn it with oxygen to make SO2. Then, direct the stream of SO2 gas into a reactor bed with some vanadium pentoxide catalyst and extra oxygen gas to make sulfur trioxide gas which is the acid anhydride of sulfuric acid. vanadium pentoxide is added to in the contact phase of making of sulfuric acid. V2O5 acts as a catalyst at 450�¢?? where SO2 is made to react with the left over O2 in the first step. Vanadium pentoxide series of sulfuric acid catalysts can be used in the process of sulfuric acid production, to be more specific, is the process of SO2+I/2O2---SO3. With the help of Vanadium Catalyst, the rate of conversion can be improved greatly. It can guarantee the air speed of operation to add 10-20% more when using type star ring catalysts or ring catalysts. Vanadium catalyst can be applied in many fields, such as, sulfur-based acid production, pyrite-based acid production, nonferrous smelting gas-based acid production, gypsum-based acid production etc. Type S101 Catalyst is a medium broad temperature vanadium catalyst which promotes the oxidation from SO2 to SO3, and it is developed by China. With 20 years of manufacturing S101 catalyst, it has reached the international advanced level. Due to its high-quality and steady performance, The advantages of S101 are as listed. Wide applicability, broad range of temperature, high conversion, and high mechanical strength etc. Ring or plum blossom shaped catalysts have solved some problems that cylinder-shaped catalyst encountered; namely, they are small pellets, high pressure drop and high energy consumption, bad resistance of dust accumulation. Type S101 series are broad temperature catalysts which suit for every bed of converter. Type S108 Series sulfuric acid catalysts are invented in early 80 s by China. The advantages of them are outstanding. In general, they are low ignition temperature, high activity in low temperature, high-resistant crushed strength etc. If can be used together with medium temperature type catalyst, such as, S101, you can make more profits; for instance, high conversion, and lowering environmental pollution. Type S108 is low temperature catalysts which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission.

Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices. The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst. Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.

Diesel Particulate Filters (DPF) utilize cordierite wall-flow monoliths to trap the soot produced by medium to heavy-duty engines in off-road, on-road and stationary applications. The cylindrical filter element consists of many square parallel channels running in the axial direction, separated by thin porous walls, as shown below. The channels are open at one end and plugged at the other, which forces the particle laden exhaust gases to flow through the walls. Gas is able to escape through the pores in the wall material. Particulates, however, are too large to escape and are trapped in the filter walls and in the inlet channels. A proprietary noble metal catalyst is coated onto the inside surface of the filter monolith. Diesel oxidation catalyst(DOC) also as the core components of exhaust gases filtration system, it can promote chemical oxidation of CO and HC as well as the SOF portion of diesel particulates. We also supply Catalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, Diesel Particulate Filters, DPF, SCR catalyst ,Ceramic honeycomb monolith , Metal honeycomb carrier, ect.

Particulates, however, are too large to escape and are trapped in the filter walls and in the inlet channels. A proprietary noble metal catalyst is coated onto the inside surface of the filter monolith. The catalyst lowers the soot combustion temperature allowing the filter to regenerate. The accumulated soot is oxidized in the filter during regular operation of the engine. For about 25-30% of the engine operating time, the exhaust temperatures must be at least 275-300°C for proper filter regeneration when ULSD (ultra-low sulfur diesel) fuel is used.
