Patent ID: 8397509

Claim:
A process of operating a catalytic engine which consists of a catalytic fuel reformer and a turbine/turbo charger, comprising the steps of: a) Introducing a stream of a fuel mixture into an inlet of a catalytic fuel reformer's reaction zone: i) Said inlet fuel mixture comprising of fuels, steam, supplemental air and portion of exhaust gas re-circulated from said turbine/turbo charger through an exhaust line to provide heat, steam, oxygen and CO 2 to the fuel mixture, and said fuel mixture having a limited % fuels H 2 O/C ratio >3.0, O 2 /C ratio >1.0 and CO 2 /C ratio >0.05, ii) Said catalytic fuel reformer's reaction zone containing one or more supported or unsupported Pt group metal catalysts and/or oxide oxidation catalysts, b) Reacting said fuel mixture without overheating said catalysts and without coke formation in said fuel reformer's reaction zone at a temperature between 150-1200° C. and a pressure between 1 to 100 atmosphere to produce a complete combustion reformate comprising mainly of steam, CO 2 , O 2 and N 2 , c) Discharging the reformate from said fuel reformer to drive a downstream steam turbine, turbo charger or gas turbine.
