Patent ID: 8061120

Claim:
A process of generating hydrogen and CO from fuels for assisting the fuel combustion inside an engine/gas turbine using an on-board Exhaust Gas Recycle (EGR) oxidizer, comprising the steps of: a) introducing a stream of a fuel mixture through an inlet in one end of an EGR oxidizer, i) said a fuel mixture comprising fuels, steam, air and portion of engine/gas turbine exhaust gas re-circulated through an exhaust gas recirculation line, and said fuel mixture having a H 2 O/C ratio between 0.50 and 10.0, an O 2 /C ratio between 0.15 and 1.5 and a CO 2 /C ratio between 0.00 and 0.5; ii) said EGR oxidizer comprising two reaction zones and each reaction zone containing one or more supported or unsupported Pt group metal catalysts for the production of H 2 and CO from said fuel mixture; and iii) said exhaust gas recirculated through the recirculation line providing heat, O 2 , steam and CO 2 to said first reaction zone within said EGR oxidizer, b) reacting first said fuel mixture over said Pt group metal catalysts within said first reaction zone of the EGR oxidizer by a reforming process at a temperature between 150-1200° C. with pressure between 1 to 10 atmosphere to convert up to 100% of said fuels and to produce a reformate comprising steam, H 2 , CO, CO 2 , N 2 , and unconverted fuels, c) reacting further said reformate from the first reaction zone over said catalysts in the second reaction zone of the EGR oxidizer at a temperature between 100-500° C. to produce extra H 2 from CO and steam by water gas shift reaction, and d) discharging the reformate from the second reaction zone through an outlet in the other end of the EGR oxidizer to a downstream engine/gas turbine either to complete the combustion of said fuels inside the downstream engine/gas turbine, or to use the reformate directly to regenerate the diesel particulate filters, NO x traps and pollution traps.
