Diatomite Supported Vanadium Catalyst

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. Chinese traditional types of catalyst S101 series broad temperature and S108 series low temperature, which are equivalent to the types of BASF O4-110/O4-111, TOPSOE VK38/VK48 and MECS LP-120/LP-110 with shapes cylinder, ring, star ring and Triangular prism. Type S101 Catalyst is a medium broad temperature vanadium pentoxide catalyst to promote the oxidation of SO2 and O2 to give SO3, which is developed independently in China. This catalyst has a manufacturing history of over 40 years with high standard quality and steady performance. Advantages: This catalyst has advantages of wide applicability, broad range of temperature, high conversion and high mechanical strength. Ring or Plum Blossom Ring shaped catalysts have solved some problems with cylinder shaped catalyst, which are small pellets, high pressure drop and high energy consumption, bad resistance of dust accumulation. Type S108 Series sulfuric acid catalysts are invented in early 80sâ?? 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. 1). Type S101 series are broad temperature catalysts which suit for every bed of converter. 2). 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.

Vanadium pentoxide catalyst Sulphuric acid catalyst (also named vanadium pentoxide catalyst) suits for that sulphuric acid plants use the contact process to promote the oxidation of so2 and o2 to give so3. Based on more than 30 yearf+s experience with sulfuric acid catalyst, our factory can manufacture several types of catalysts in different shapes and sizes, such as s101, s101-2h, s101-3mh, s101-3bz, s108, s108-2h, s108-3mh, s108-3bz, s107, s107-2h, s107-3mh, s109, s106. Our manufacturing technique is advanced. The carrier is treated by repulped stock processing, washed by hot concentrated acid, pretreatment of calcinations, and added several rare accessory ingredients, then molded by using advanced patent technology. The performance of our catalysts is excellent, with high activity, low ignition temperature, high mechanical strength, low losses of screening, and long life. As for star ring type of catalyst, it has advantage of large surface area, low pressure drop, and good resistance of dust accumulation. 125kg/steel drum

This kind of catalyst which is also named sulfuric acid catalyst, and specially used to convert sulfur dioxide into sulfur trioxide in the process of sulfuric acid manufacturing. The catalyst is filled into each bed of the convertor. Generally speaking, the convertor equipment can be classified into two large systems. Double contact double absorption and single contact single absorption. We can supply mainly two large series catalyst as below. 1). Type S101 series of broad temperature catalyst The ignition temperature is 400â??. For continuous operation, the temperature should be in the range 420-620â??, which is suitable for each bed of converter for its high and stable activity. 2). Type S108 series of low temperature catalyst The ignition temperature is 380â?? and operating temperature 400-540â??, 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). Different catalyst shape is the reason to reduce catalyst bed pressure drops which translates directly into energy savings as a result of reduced blower power consumption. Reduced pressure drops also allow more dust to accumulate before pressure drops increase to the point where the plant must be shut down for catalyst screening. The catalyst shape must achieve all of the above without compromising on catalyst activity or mechanical strength. 4). The length of catalysts can be made according to the userâ??s requirement.

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.
