# Separation of carbon mono-oxide and hydrogen

What is a shift converter in chemistry?

For example in "inorganic chemistry by JD lee" while discussing the ways in which CO and $$H_2$$ can be separated the book stated that water gas(that is the mixture of CO and $$H_2$$) can be mixed with steam, cooled to $$400^◦$$C and passed over iron oxide in a shift converter, thus giving $$H_2$$ and CO$$_2$$.

What is the meaning of a shift converter in this context?
