Sulfur recovery catalyst of the current widespread use of activated alumina series in Klaus devices working conditions, often due to the presence of traces of oxygen and organic sulfur in the feed gas, the formation of sulfate, resulting in the catalyst specific surface area declined, the activity graduallyloss. Under normal circumstances, the life of the sulfur recovery catalyst activated alumina series in about a year in high oxygen, the inactivation rate faster. Hydrolysis of organic sulfur often need a higher reaction temperature, the temperature does not match with the Claus reaction, is not conducive to the normal conduct of the Claus reaction.
Activity of titanium dioxide sulfur recovery catalyst most important feature is that it has a low-temperature organic sulfur conversion rate, "deaerator" function, is difficult to form sulfate on the catalyst. Also play a role in the Claus unit, in addition to promoting the Claus reaction purification, thereby protecting the normal use of the sulfur recovery catalyst to extend the life of the activated alumina catalyst.
The catalyst is mainly used for the catalytic Claus sulfur recovery process of hydrogen sulfide and sulfur dioxide in the reaction of elemental sulfur. The product to better engage sulfate has been successful in multiple sets of domestic and foreign industrial device for industrial applications.
Note:
1.In the case of high organic sulfur content, may be appropriate to reduce the airspeed to meet process requirements.
2.Filling in the alumina sulfur recovery catalyst for the upper, which is equivalent to 1/3 of the number of alumina catalyst, the use of timber and on the surface evenness and avoid bias.
3. A higher oxygen content will affect the organic sulfur conversion, but conversion rate is not affected after the return to normal.
