Claus Tail Gas Hydrogenation Catalysts For Coal Chemical Industry

Features:

1. Claus tail gas hydrogenation catalysts for coal chemical industry with modified Al2O3 as carrier and Co and Mo as active components.

2. Good low-temperature hydrogenation activity and hydrolysis activity for organic sulfur. The low operating temperature enables great reduction in energy consumption of Claus tail gas hydrogenation unit.

3. AMC-LSH-03 has good O2 resistance and O2 scavenging performance, suitable for treating oxygen-consisted process gas.

4. Low sulfiding temperature, good adaptablility to fluctuation of operating conditions, good operation flexibility, excellent stability in activity and long service life.

5. The pore volume and surface ratio are large and the active components are distributed evenly.

6. Hydrogenation activity and organic sulfur hydrolysis activity are high.

Operating conditions:

Physico-chemical properties:

Loading:

1) Before loading the claus tail gas hydrogenation catalysts for coal chemical industry, it is necessary to clean up the inside of the reactor first, spread the stainless steel wire mesh, stacked and flattened 10cm high φ20mm porcelain ball and 5cm high φ8~10mm porcelain ball, then load the catalyst, the wire mesh is required to ensure at least 3 years of time.

2) The claus tail gas hydrogenation catalysts for coal chemical industry are poured out from the bucket. If more fine powder is found, it can only be used after sifting more than 10 mesh. When loading, the catalyst should be first loaded into the cloth bag and then lifted into the reactor. The falling height of the catalyst should not be more than 50cm.

3) In the process of catalyst loading, the board should be paved. The loading personnel must stand on the board of catalyst bed bedding for loading operation, it is strictly prohibited to use metal instruments to dig. After the catalyst is loaded to a predetermined height, the surface of the catalyst is paved with wooden tools, and a layer of φ8~10mm porcelain ball with a height of 10cm is laid on it, the impact of the air flow on the surface of the catalyst is slowed down with dry.

4) After catalyst loading, the feed port should be sealed immediately. Before starting, water vapor and process gas should be avoided from entering the reactor. Before starting, dry air should be used to purge the bed powder.
