Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water.
Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size.
Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

When manufacturing various sulfides such as sulfate pulp, rayon, artificial cotton, rubber, carbon disulfide, etc., hydrogen sulfide gas is often discharged. In some chemical reactions, unstable sulfur-containing compounds will also decompose into hydrogen sulfide. For example, in coking, refined petroleum and metal smelting, hydrogen sulfide, as a conventional waste gas, is very easy to leak into the air. The decomposition of sulfur dyes can also release hydrogen sulfide gas.

Take the sulfur and burn it with oxygen to make SO2. Then, direct the stream of SO2 gas into a reactor bed with some vanadium pentoxide catalyst and extra oxygen gas to make sulfur trioxide gas which is the acid anhydride of sulfuric acid.
vanadium pentoxide is added to in the contact phase of making of sulfuric acid. V2O5 acts as a catalyst at 450�¢?? where SO2 is made to react with the left over O2 in the first step.
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.
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.
Type S101 series are broad temperature catalysts which suit for every bed of converter.
Type S108 Series sulfuric acid catalysts are invented in early 80 s 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.
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.

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 catalystâ??s support maintain its structure integrity, and thereby the active components can disperse into the earthâ??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 catalystâ??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.
