Quantity: 200 Specs:0.4-1.2, 1-3, 2-4, 3-5, 4-6, 5-7, 6-8 Price:1000 USD Metric Tons Payment Method: TT Titanium Dioxide Sulfur Recovery Catalyst Titanium Dioxide Sulfur Recovery Catalyst is a kind of TiO2 / Al2O3 auxiliary type sulfur recovery catalyst, through the special impregnated preparation technology loading active components TiO2 on the activated alumina carrier, thus it has higher activity of hydrolysis reaction to the organic sulfide such as COS and CS2. TiO2 sulfur recovery catalyst is mainly used for catalysing hydrogen sulfide and sulfur dioxide chemical reaction generated elemental sulfur in the claus sulfur recovery process, processing all kinds of acid gas containing H2S. Can be used in any level converter used of sulfur recovery device, also can fill in the lower part of the first reactor for the hydrolysis reaction of organic sulfide COS/CS2. This product should be moistureproof, do not contact with other chemicals Store airtight 3 ~ 5 years, quality is not affected. Introduction Currently widely used activated alumina sulfur recovery catalyst, under the working condition of Klaus device, often forming sulfate due to the presence of trace oxygen and organic sulfur in feed gas, which lead to the specific surface area of catalysts decreased, and activity gradually lost. Under normal circumstances, the service life of activated alumina sulfur recovery catalysts in a year or so, under the condition of high oxygen, the deactivation is faster. Organic sulfur hydrolysis often requires a higher reaction temperature, but it doesn't match the temperature of claus reaction, so it is not conducive to the normal reaction of claus. Sulfur recovery catalyst of active TiO2 base solve above problems, its biggest characteristic is that it has high organic sulfur conversion rate at low temperature, strong "deoxidation", and difficult to form sulfate on the catalysts. In claus device, in addition to promoting claus reaction, it also has purifying effect, thus ensure the normal use of the sulfur recovery catalyst and prolong the service life of activated alumina catalyst. TiO2 sulfur recovery catalyst is mainly used for catalysing hydrogen sulfide and sulfur dioxide chemical reaction generated elemental sulfur in the claus sulfur recovery process, processing all kinds of acid gas containing H2S. Can be used in any level converter used of sulfur recovery device, also can fill in the lower part of the first reactor for the hydrolysis reaction of organic sulfide COS/CS2. Note In the case of high organic sulfur content, decrease the airspeed can meet the technological requirements. Loading this product above alumina sulfur recovery catalyst, equal to 1/3 of alumina catalyst quantity, scrape to evenness on the surface with boards, avoiding the bias current. High oxygen content will affect the organic sulfur conversion, but the conversion rate is not affected after oxygen return to normal. Sulfur Recovery Catalyst Introduction It produces large amounts of H2S gas in the process of natural gas purification and sulfur crude oil processing, in order to protect the environment and recovery of sulfur, people use claus technology processing H2S sour gas, and activated alumina sulfur recovery catalysts play an important role in this process. Activated alumina sulfur recovery catalyst has very large pore structure, pore radius larger than 700? are more than 70% of the total pore volume. This macroporous structure can reduce the diffusion resistance, make the reactant diffusing into catalyst internal quickly, and let generation of sulfur spread out from catalyst internal quickly, so activated alumina sulfur recovery catalyst compared with ordinary alumina catalyst has higher catalytic efficiency and longer service life. Activated alumina sulfur recovery catalyst has large porosity ratio, high specific surface area, good thermal stability, high strength, small abrasion ratio, resistance to sulfate poisoning, high organic sulfur hydrolysis rate, long service life. |
