Abstract:
1. A dynamic sulfur tolerant process with inline acid gas-selective removal for converting sulfur bearing carbonaceous fuels into hydrogen or hydrogen rich gases suitable for use in fuel cells or chemical processing applications, comprising the following steps: vaporizing liquid fuels and water and preheating one or more feeds in a vaporizer/preheater by transferring the sensible heat from reformate gas; feeding fuel, water and oxidant over a sulfur tolerant catalyst in an AHR to yield a hydrogen rich reformate gas to combine the heat effects of the partial oxidation, steam reforming reactions, preheat and heat losses; converting CO and steam in the reformate gas to additional hydrogen and CO vaporizing and superheating water fed to a WGS boiler coil in a steam generator; removing selectively substantial amounts of acid gas (H further reducing CO and CO interchanging heat between hydrogen rich gas and sweep gas in a heat interchanger; and wherein sulfur tolerant AHR and WGS catalysts are used to make a combined AHR/WGS reactor ahead of the ASMS to be sulfur tolerant.
