Abstract
A steam/hydrocarbon reformer employing a convection-heated pre-reformer is disclosed. The pre-reformer comprises catalyst-filled tubes disposed in the transition section between the radiant and convection sections. The pre-reformer tubes are transverse to the flow of flue gas from the radiant section. The pre-reformer achieves 10-20% of the total reforming load, and can be installed as a module or modules between the radiant and convection sections without increasing the size of the reformer.
