Product Description
Sulfur Recovery Catalyst
Sulfur recovery refers to a gas desulfurizing process, or Claus process, which recovers elemental sulfur from gaseous hydrogen sulfide. The sulfur recovery catalyst recovers, in addition to the sulfur from the gaseous hydrogen sulfide found in raw natural gas, hydrogen sulfide that is contained in by-product gases and derived from refining crude oil and other industrial processes.
Our PSR series sulfur recovery catalyst, with alumina or titania acting as the carrier, is made by adding promoter and caking agent. The catalyst is used in the Claus units for sulfur recovery from acidic gases containing H2S and organic sulfides like COS and CS2, with the total sulfur conversion rate up to 95% or even higher. The sulfur recovery catalyst is commonly applied in the oil refinery, fertilizer, natural gas, petrochemical industries, and others.
Schendly has developed a series of SRU catalyst for sulfur recovery as follows.

Note: mark of * refers to the calculation based on H2S content of 60 percent(ν) in acid gas and maximum sulfur conversion rate, as well as by means of the analyzer and detector with H2S/SO2 on-line proportion analysis and control. For the device for high-temperature thermal admix and grade-2 catalytic conversion, the filling volume of PSR-41 catalyst accounts for 1/3~1/2 the bed volume. In case that H2S content in acid gas is less than 40%(ν), the filling volume of PSR-41 catalyst shall account for 1/2~2/3 the bed volume, and the filling volume of PSR-31 catalyst shall account for 1/3~1/2 the bed volume.

SCHENDLY Industry: A professional manufacture for Catalyst Carriers.
Carriers are the breath of life to the catalysts. The appearance, components, and properties of carriers have significant influence the performance of catalysts. Schendly designs the most suitable carriers for the catalysts to maximize the efficiency and service life.
We use magnesia, titanium dioxide and composit...E
Metallic oxide as the raw materials to supply extruded, sphere,
Ring and cylinder, cellular texture and unique shape carriers for
Special demands of our customers. We also work collaboratively
With famous institutions, devoting our ideas and passions to
Create new carriers all the time.
We produce various types of catalyst carriers including extruded catalyst carriers, sphere shapes carriers, cylinder carriers, and cellular texture carriers.
The appearance includes solid extrudates, trifolium extrudates, quadrifoil extrudates, papilionaceous extrudates, micro-sphere, standard sphere, oval sphere, porous-sphere, ribbed sphere, rectanglar, circular, oval, etc.
The main physical properties are as following:
Bulk density: 0.45-0.8 g/cm3;
Pore volume: 0.5-0.8 cm3/g;
Specific surface area: 150-350 m2/g
