NOVELTY - A dynamic sulfur tolerant process with inline acid gas-selective removal for converting sulfur bearing carbonaceous fuels into hydrogen or hydrogen rich gases for fuel cells or chemical processing applications, uses sulfur tolerant catalyst in an autothermal hydrodesulfurization reforming (AHR).    USE - For converting sulfur bearing carbonaceous fuels into hydrogen or hydrogen rich gases for fuel cells or chemical processing applications.    ADVANTAGE - The invention provides an economical, efficient and compactly configured sulfur tolerant dynamic fuel process which uses sulfur tolerant catalysts and hardware designs that enable the conversion in an energy efficient manner while maintaining desirable performance characteristics such as rapid start-stop or fast response to load change capabilities.    DETAILED DESCRIPTION - A dynamic sulfur tolerant process with inline acid gas-selective removal for converting sulfur bearing carbonaceous fuels into hydrogen or hydrogen rich gases for fuel cells or chemical processing applications, comprises:    (a) vaporizing liquid fuels and water and preheating feed(s) in a vaporizer/preheater by transferring the sensible heat from reformate gas;    (b) 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;    (c) converting carbon monoxide (CO) and steam in the reformate gas to additional hydrogen and carbon dioxide (CO2) via a water gas shift (WGS) reaction in a WGS reactor;    (d) vaporizing and superheating water fed to a WGS boiler coil in a steam generator;    (e) removing acid gas (hydrogen sulfide (H2S) and CO2) in WGS product gas in an acid gas-selective membrane separator (ASMS);    (f) further reducing CO and CO2 concentration levels in a methanator; and    (g) interchanging heat between hydrogen rich gas and sweep gas in a heat interchanger.    An INDEPENDENT CLAIM is also included for a dynamic sulfur tolerant system for producing hydrogen or hydrogen rich gases from sulfur bearing carbonaceous fuels for fuel cells and chemical processing applications, comprises an AHR for reforming sulfur bearing carbonaceous fuels to produce a reformate; a WGS reactor for converting CO and water in the reformate to additional hydrogen and CO2; and an upgrade comprising an inline acid gas-selective remover for decreasing concentration of CO2 and H2S in the reformate to produce a retentate comprising hydrogen or hydrogen rich gases for fuel cells and chemical processing applications.
