Product Description
Sulfuric Acid Catalyst CHP80B
CHP80B vanadium pentoxide catalysts are high performance catalysts . They are the vanadium catalysts used for the oxidation of sulfur dioxide to make sulfuric acid.
It is our unique making process that makes the diatomaceous earth as catalyst’s support maintain its structure integrity, and thereby the active components can disperse into the earth’s micropores uniformly and the pore radius thus distributes in a more wide range.
With imported diatomaceous earth as supports, our CHP80B catalysts have more brilliant porosity and larger surface area, making the catalysts show better in activity, bulk density and pressure drop.
All those unique features including special making process, special active components and excellent imported supports etc. ensure that the final catalysts can provide longer service life, wider screening span and less screening loss. In normal operating conditions, the catalyst’s service life is 8 to 15 years, the screening cycle is 2 to 5 years, and the screening loss is 10~15%.
With the broad compatibility for various raw materials, scales and processes of sulfuric acid plants, CHP and VCs series can help to meet the requirements of increasingly stringent sulfur dioxide emission and then guarantee the stable and long operating cycle of sulfuric acid plants.
Performance
CHP80B can keep its excellent activity even under conditions of low temperature, strong SO3 and thin O2. Compared to most other similar catalysts, the performance of CHP80B is substantially improved. Therefore, it is mainly used for the bottom half of pass 2 before the first absorption or for the bottom half of pass 1 after the first absorption.
