QDB-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.
QDB-01 is a patented product developed by our company. Compared with traditional alumina carrier catalysts, QDB-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.
