Product Details

Vanadium pentoxide series of sulfuric acid catalysts could 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.

1: Broad Temperature Type of Sulfuric Acid Catalyst: S101.

1) Type S101:

There are four products of type S101, in details, they are S101 (Cylinder); S101-H (Ring); S101-MH (Star ring); S101-YH (Three-rib 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.

2: Low Temperature Type Sulfuric Acid Catalyst: S108.

Type S108: S108 Cylinder; S108-H (Ring); S108-MH (Star ring); S108-YH (Three-rib cylinder)

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.

Operating Requirements

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.

3). Install the catalyst beginning at the far side of the converter working back towards the manway. Use the marks on the converter wall as a guide for leveling the catalyst. Avoid walking directly on the catalyst. Use plywood sheets or boards laid on top of the catalyst if access is required across the top of the bed.

4). New catalyst is easy to get damp, so it is better to choose fine days to sift it and load it. Time that catalyst is exposed in air should be as short as possible.

5). Catalysts used in low temperature beds can be moved to high temperature beds, but contrarily it can’t be loaded. New catalysts should be loaded in the surface of each bed, and separated from used catalysts with stainless steel nets.

6). It should inspect the pressure drop of each bed before repairing, and inspect the activity of catalysts in each bed before loading, so that supply some information for screening, loading or removing.
