7198862 B2 abstract the invention provides a multistep process for preparing a low sulfur reformate gas for use in a fuel cell system the process comprises catalytic steam reforming of a reactant gas mixture comprising sulfur containing hydrocarbons and steam in a first step to make a reformate reducing the carbon monoxide content of the reformate in a second step passing the reformate over a sulfur absorber either directly after the first step or after passage through the second step and desorbing the sulfur components optionally absorbed on the catalysts in the reforming and reducing process steps by periodically raising the temperature so as to cause the sulfer components to pass to the absorber wherein the temperature of the absorber during operation of the process is always kept within a temperature interval which is an optimum for the absorber application_number US 17257002 A description the invention will now be described in connection with preferred embodiments these embodiments are presented to aid in an understanding of the present invention and are not intended to and should not be construed to limit the invention in any way all alternatives modifications and equivalents which may become obvious to those of ordinary skill on reading the disclosure are included within the spirit and scope of the present invention this disclosure in not a primer on the.
