Cesium Series Catalyst

This Cesium Vanadium Catalyst is mainly used in the Section I upper part, Section III, Section IV and Section V of the converter. Operating temperature is 390 -620 S112 series cesium vanadium catalyst is made by taking refined composite diatomite as high-performance carrier with new techniques. Alkali metal cesium and potassium compounds are adopted as promoters so that vanadium pentoxide and promoters uniformly and fully penetrate into the carrier in the form of solution. The cesium vanadium catalyst is thus refined. S112 low temperature series vanadium catalyst has high activity level, especially in the temperature range of 390-620 . Its ignition temperature is 320 . The vanadium catalyst has the following features: 1.The reaction speed is faster than that of ordinary catalyst, and it is especially suitable for the low atmosphere conditions of high concentration of sulfur dioxide or oxygen and sulfur dioxide in the Section I. Compared with S108 ordinarylow-temperature catalyst, it can effectively reduce the inlet temperature by about 20 2.It has good low-temperature activity and can greatly reduce sulfur dioxide emissions when used in the Section IV and V of the converter. 3.Under the reaction atmosphere with high impurity content and harsh conversion conditions, it has strong pulverization resistance and long service life.

We can mainly supply three series catalyst as below, which are equivalent to overseas brands BASF-O4-110/O4-111, TOPSOE--VK38/48/59/69 and MECS-LP/XLP-120&110. Type S101(04-110/VK38/LP-110) There are four products of type S101, in details, they are S101 (Cylinder); S101-H (Ring); S101-MH (Star ring); S101-YH (Three-Ribs Cylinder). 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. 2.Type S108: S108 Cylinder; S108-H (Ring); S108-MH (Star ring); S108-YH (Three-Rib Cylinder) (O4-111/VK48/LP-120) Type S108 Series sulfuric acid catalysts are invented in early 80s�¢?? 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. 3.LS112 Type Cesium Catalyst(VK59/69/Cs120/110) Low ignition temperature; higher activity in low temperature; high-resistant crushed strength, high anti- poison; high anti- pulverization etc. LS112 cesium-promoted catalyst integrates not only the active constituent of vanadium pentoxide and the promoters of cesium and potassium salts, but also the carrier of select diatomaceous earth. Its activity under low and high temperature conditions keeps high due to the unique manufacturing process and optimized formulation. Cesium-promoted catalyst enables new opportunities for improvement in start-up time, energy efficiency of electricity throughout the operating cycle and strong reduction in SO2 emission that far lower than national standard. The product is the all-around catalyst suited for all stages in converter due to its low ignition temperature and good heat tolerance under high temperature condition. Cs series enables the compliance with pollutant emission standards due to its enhanced activity and longer service life.

Beta Zeolite β Molecular Sieve For Catalyst Beta zeolite,having a unique three-dimensional 12-membered ring cross channel structure,is composed by mixing two polycrystals which are closely related to each other in the structure,and the two polycrystals are composed of the tetrahedral structure units which are symmetric based on the same center and arranged according to the layer.The two structures are composed of the tertiary structure units(TBU)which are symmetric based on the same center,wherein these TBUs are arranged in layer and subsequently connected in the form of left hand and right hand,This connection causes the twist along the channel of the direction C. Beta zeolite shows an excellent catalytic performance in catalytic cracking,hydrocracking,hydroisomerization,hydrodewaxing,aromatics alkylation,olefin hydration,olefin etherification and other petroleum refining and petrochemical processes.

Desheng is a new scientific and technological enterprise specializing in the research and development, production and sales of blood collection additives, chemiluminescence reagents, biological buffers and in vitro diagnostic reagents. Acridine ester series of products are the company's research and development of ultra-high sensitivity chemiluminescence substrate reagents. Under alkaline conditions, the acridine ester molecules can be attacked by hydrogen peroxide to form dioxane, which is unstable and decomposes into CO2 and n-methylacridone in the electron excited state. When it returns to the ground state, it emits light with wavelength of 430 nm. It does not need catalyst, and the luminescence system is simple. Desheng has seven acridine ester products with different groups: 1. Ae-nhs (traditional acridine ester); 2. Dmae-nhs; 3. Me-dmae-nhs; 4. Nsp-dmae-nhs; 5. Nsp-sa-nhs; 6. Nsp-sa; 7. Nsp-sa-adh. These acridine esters produced by Desheng have the characteristics of high purity and small difference between batches. Besides, it provides other immune reagents for matching use and provides a complete set of technical services and technical support.
