Catalyst for water shift reactions:

Iron -Chromia base Catalyst

Catalyst for water shift reactions:
For high temperature shift conversion reaction where Carbon dioxide is produced from Carbon monoxide on catalyst of Iron /Chromia which has optimum shape of tablets and has dimensions with diameter 6 mm and height 6 mm, it life times can be expected greater than 5 years.


For further reducing carbon-monoxide and thereby increase the H2 yield for Ammonia synthesis. The Low Temperature shift catalyst is a combination of copper and zinc oxide and is active at lower temperature where restriction in conversion due to equilibrium are minimized. But LT shift catalyst is very sensitive for high temperature , poisoning and contamination by water. It is made as tablets shape and has dimensions of 4.3mm diameter and 3.2mm height, with a lifetime expected to more than 5 years.
