| B207 type low-temperature CO shift catalyst, an
improved successor to B202, B204 and B206 catalysts, was developed
and produced by Research Institute of NCRI to meet the demand
of saving energy in synthetic ammonia plants. It is widely used
in the synthetic ammonia plants and hydrogen-generating plants
with natural gas, petroleum associated gas, light oil or coal
as raw material, especially in the plants operating on low ratio
of steam to dry-gas for energy saving.

Commercial Application
B207 catalyst has been successfully used in large-and medium-size
synthetic ammonia plants in China. The results show it has
high activity and stability in the ammonia plants operating
on low ratio of steam/dry-gas for energy saving. The indexes
of B207 are equal or superior to the imports now used in large-size
ammonia plants in China.
