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.

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. The varieties for the typical products of Beta Zeolite produced by JiuLong Chemical Co.,Ltd.are listed as follows,and the other products of this series also can be produced according to the requirements of the user: Detailed Product Description SiO2/Al2O3: 40 Color: White Powder Cation: Sodium SiO2/Al203: 25 SO4: 0.4 Cl-: 90ppm D50: 7um FCC catalyst , Beta Zeolite,Zeolite Beta,Beta Molecular Sieve SiO2/Al2O3 Mole Ratio: 25-40 Nominal Cation Form: Sodium/Hydrogen Na2O Weight %: 0.1 Surface Area, m2/g: 540 Zeolite beta β molecular sieves have three mutually intersecting 12-ring channels, it is only 12 yuan a three-dimensional pore structure of zeolite ring. β zeolite having high hydrocracking, hydroisomerization catalytic activity and adsorption capacity of linear paraffins, and good resistance to sulfur and nitrogen poisoning. It can be used in the petrochemical industry of benzene with propylene olefin system cumene, cumene metathesis diisopropylbenzene, toluene Isopropylation, aromatics alkylation, transalkylation diisopropylbenzene, propylene ether, methanol aryl structured, propylene oxide and acetic ether of phenol methylation, methylation of aniline, toluene transalkylation preparation of cumene and toluene disproportionation and transalkylation reaction with a catalyst such. β-type USY zeolite used in conjunction with the increase of the octane number of gasoline.

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.
