Abstract
The present techniques are directed to a system and methods for operating a gas turbine system. An exemplary gas turbine system includes an oxidant system, a fuel system, and a control system. A combustor is adapted to receive and combust an oxidant from the oxidant system and a fuel from the fuel system to produce an exhaust gas. A catalyst unit including an oxidation catalyst that includes an oxygen storage component is configured to reduce the concentration of oxygen in the exhaust gas to form a low oxygen content product gas.
Claims40
A gas turbine system, comprising:
- an oxidant system;
- a fuel system;
- a control system;
- a combustor adapted to receive and combust an oxidant from the oxidant system and a fuel from the fuel system to produce an exhaust gas;
- and
- a catalyst unit comprising an oxidation catalyst that comprises an oxygen storage component configured to reduce the concentration of oxygen in the exhaust gas to form a low oxygen content product gas.
A heat recovery unit, comprising:
- a heat exchanger configured to remove heat energy from an exhaust gas;
- and
- a catalyst bed configured to reduce a concentration of a target gas in the exhaust gas, wherein the catalyst bed comprises an oxygen storage component (OSC).
A method for combusting a fuel in a gas turbine, comprising:
- providing a fuel to a combustor on a gas turbine;
- providing an oxidant to the combustor;
- combusting the fuel and the oxidant in the combustor to produce an exhaust gas;
- and
- passing at least a portion of the exhaust gas through a catalyst bed comprising a catalyst having an oxygen storage component (OSC) catalyst to form a low oxygen content product gas.
