04 has the following outstanding features:
High conversion activity and activity stability
The special active carrier additive is selected. Due to the synergistic effect of the active carrier, the additive and the active component, the conversion activity of the catalyst is improved, especially the conversion activity and activity stability of the catalyst under high temperature and low sulfur conditions.
Strong ability to hydrogenolyze and hydrolyze organic sulfur
The addition of composite alkaline materials enhances the surface alkalinity of the catalyst and improves the conversion activity of the catalyst to organic sulfur, especially under low reaction temperature conditions. At the same time, due to the improvement of organic sulfur conversion activity, when the H2S in the raw gas is low, it can better maintain its own sulfurization form, thereby improving the deoxidation performance of the catalyst.
Good hydration resistance
The addition of special hydration resistance additives can significantly reduce the adsorption activity of L acid on Al2O3 particles, thereby reducing the ability of the Al2O3 component in the carrier to hydrate, and improve the hydration resistance of the catalyst, so that the catalyst does not hydrate or phase change when used under harsh conditions with high pressure, and has high hydration resistance and structural stability.
Excellent carbon burning regeneration performance
Advanced carrier preparation technology is adopted and inorganic pore-forming agents are added. On the premise of ensuring high crushing strength, the pore structure of the catalyst is adjusted and the macroporous powder rate is increased, which is conducive to the rapid escape of CO2 and other gases generated during the carbon burning regeneration process, protecting itself from or less damage, thereby improving the carbon burning regeneration performance of the catalyst.
03 Sulfur-Resistant Shift Catalyst
Product features and range of applications:
03 is a new type of CO sulfur-resistant shift catalyst with magnesium aluminum spinel as carrier, prepared by special method and containing multi-component composite additives. It is suitable for the process of producing shift process gas and city gas from coal or residual oil as raw materials, especially for the process of producing hydrogen, ammonia synthesis gas, city gas and carbonyl synthesis gas from coal or residual oil as raw materials by high-medium pressure gasification.
03 catalyst does not contain alkali metal additives, so the activation temperature is higher and the low-temperature activity is worse than QDB-04. However, due to the high content of active components, the special preparation method and the active stability additives, the outstanding advantage of QDB-03 catalyst is that it has good activity and structural stability when used under high pressure, high space velocity and high water/gas conditions.

Product features and range of applications:
01 is a new type of CO sulfur-tolerant shift catalyst with magnesium aluminum spinel as carrier and special active additives. It is suitable for the process of producing shift process gas and city gas with coal or residual oil as raw materials, especially for the process of "full low shift", "medium low shift" and "medium low low" in atmospheric pressure fixed bed gas production.
Product Details
01 is a patented product developed by our company. Compared with traditional alumina carrier catalysts, 01 has the following outstanding features:
Adopting advanced catalyst preparation technology, the strength and anti-powdering ability of the catalyst are improved. It can effectively avoid the shortcomings such as increased bed resistance, catalyst agglomeration, difficulty in unloading and even affecting the normal operation of industrial production caused by the pulverization of the catalyst itself, extend the continuous start-up time of the device, increase the output of the device, and improve the economic benefits of the enterprise.
Adding special active components to activate the carrier improves the activity and activity stability of the catalyst and extends the service life of the catalyst.
Adding new additives improves the low-temperature activity and low water-gas ratio resistance of the catalyst, reduces the operating temperature of the entire reaction system, and saves energy.
