Abstract
The invention described herein proposes steam reforming processes in two stages, the first stage being passing a synthesis gas stream through a first catalyst bed comprising an alkali metal and/or iron titanate based catalyst, and a second stage comprising at least a second catalyst bed containing a refractory supported metal catalyst, preferably having NiO as the metal phase supported with barium hexa-aluminate.
