Sulfuric Acid Catalyst
Sulfuric acid (alternative spelling sulphuric acid) is very important essential basic chemical materials which has a wide range of applications. It is also a central substance in the chemical industry, the principal uses include mineral processing,fertilizer manufacturing,oil refining, waste water processing, and chemical synthesis. Sulfuric acid is widely produced with different methods, such as contact process, wet sulfuric acid process, lead chamber process and some other methods.However, whether you produce sulfuric acid from elemental sulfur(S) or from spent sulfuric acid(WSA) or clean sulfurous gases, SINOCATA offers our high activity catalysts which provide high conversion, high energy efficiency, low pressure drop, production stability, and exceptionally long life applied in many sulfuric acid plant.
High Vanadium Pentoxide Sulfuric Acid Catalyst
Standard vanadium pentoxide catalyst contains approximately 6-8wt% of vanadium pentoxide. High vanadium pentoxide catalyst contains 7-9wt% vanadium pentoxide combined with a modification to the chemical composition of the active phase.The activity is 15-20% higher than standard vanadium pentoxide catalyst.
Cesium Promoted Sulfuric Acid Catalyst
The vanadium pentoxide catalyst have a strike temperature of about 400 deg C to initiate a self-sustaining reaction, but cesium-promoted catalyst has a much higher activity in the low temperature range resulting in a strike temperature 20 to 40 deg C lower than the standard catalyst.The cesium-vanadium-contained catalyst can also help to shorten the start-up time, reduce the consumption of electric energy and SO2 emission (far below the national emission standards).
The SINOCATA serial sulfuric acid catalyst ensure you to achieve higher conversion rates, fast start-up, optimal energy efficiency and the lowest possible SO2 emissions.
SAP-75, a v2o5 catalyst, Dia.11.5mm, 5-ribbed ring, Bulk density: 380 – 580KG/m3, which is widely used to endure the tough bed conditions of pass 1 and pass 2 of the SO2 converter. With a unique formulation different from the traditional catalysts, SAP-75 provides more surface area and higher porosity which provide higher activity and less loading. It can also help to reduce the resistance and energy loss. Especially, its long service time can also be helpful to obtain a longer duration uninterrupted production and meet the criteria of exhaust emissions. Hollow ring cylinder and cylinder shapes are also available.
SAP-78, a v2o5 catalyst, Dia.11.5mm, 5-ribbed ring, Bulk density: 420 – 600KG/m3, which is widely used in the 2nd, 3rd, 4th and 5th passes of the SO2 converter, SAP-78 catalyst provide excellent activity even under the conditions of low temperature, high SO2 and low O2 concentrations. Hollow ring cylinder and cylinder shapes are also available.
VCS-95, a cesium-promoted catalysts, Dia.11.5mm, 5-ribbed ring, Bulk density: 450 – 650KG/m3, which is widely used any pass of the SO2 converter for sulfuric acid production. VCS-95 is a new type of vanadium catalyst produced with unique manufacturing process and optimized formulation by taking high quality diatomaceous earth as the carrier. VCS-95 exhibits high activity at either low or high temperature conditions. The Series VCs cesium-vanadium-contained catalyst can also help to shorten the start-up time, reduce the consumption of electric energy and SO2 emission (far below the national emission standards).
