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.

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.
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.
S101 catalyst is mainly composed of vanadium pentoxide and silicon dioxide. This vanadium catalyst is mainly used in the Section I lower part, Section II and Section III of the converter, with operating temperature 410 -620. The product is made of refined composite diatomite, with large specific surface area and porosity as well as low bulk density. Its bulk density is 14% -16% lower than that of similar products. The catalyst activity is 3%-5% higher than that of similar products. Other features include uniform strength, small deviation, and strong anti-chalking ability.

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.
