Abstract
A process for increasing the hydrogen content of a synthesis gas containing one or more sulphur compounds, the synthesis gas including hydrogen, carbon oxides and steam, and having a ratio, R, defined as R=(H−CO)/(CO+CO)≦0.6 and a steam to carbon monoxide ratio ≦1.8, includes the steps of (i) adjusting the synthesis gas temperature, (ii) passing the temperature-adjusted synthesis gas through an adiabatic pre-shift vessel containing a bed of sulphur-tolerant water-gas shift catalyst at a space velocity ≧12,500 hourto form a pre-shifted gas stream, and (iii) subjecting at least a portion of the pre-shifted gas stream to one or more further stages of water-gas shift.
