Hydrocarbon Steam Pre Reforming Catalysts
1. The steam reformer is the heart of the entire hydrogen production process.
2. The key factor in the conversion process is the hydrocarbon steam pre reforming catalysts.
3. Under high temperature and pressure conditions, hydrocarbons and steam undergo conversion reactions to produce CO, CO2 and H2.
Product Introduction
Product Introduction
Hydrocarbon steam pre reforming catalysts is suitable for both dry gas-based gaseous hydrocarbons and mixed feedstocks of dry gas and light naphtha, and has good adaptability, low temperature activity and stability. Through the development of high efficiency pre-conversion catalyst, the role of pre-conversion technology in reducing infrastructure investment, saving gas consumption, expanding production capacity, protecting the conversion catalyst, stabilizing the operation of the converter and extending the start-up period has been The role of pre-conversion technology in reducing infrastructure investment, saving gas consumption, expanding production capacity, protecting the conversion catalyst, stabilizing the operation of the converter and prolonging the start-up period is reflected.
Features
1)High content of nickel stably dispersed on porous carrier, resulting in good low temperature activity an activity stability.
2)Both oxidized and reduced catalysts can be supplied, the oxidized catalyst needs to be activated in situ, while the reduced one can be used directly.
3)Reduction gas is needed to project the pre- reforming catalysts during start up and shut down.
4)Introduction of hydrocarbon feedstock alone or in combination, switching or dosage adjustment of feeds does not affect the normal use of the catalyst.
5)Hydrocarbon steam pre reforming catalysts have excellent resistance to operating fluctuation and good operating flexibility. Cold feed can be introduced into reactor directly.
6)Patented product and awarded the National Prize for Science and Technology Progress.
