Abstract

A power generation system yielding exhaust providing both carbon dioxide and a preheated hydrogen source used to create liquid fuels from the reaction of the now heated hydrogen with cellulosic biomass, preferably where the hydrogen source is methanol.

Claims

1. An energy production system comprising a liquid fuel reactor having an operating pressure above a supercritical pressure of methanol wherein the liquid fuel reactor converts a cellulosic biomass with methanol into a liquid fuel and yields a reactor gas output operable to increase an energy efficiency of a combined power generating cycle with the liquid fuel reactor, wherein the power generating cycle is comprised of a gas turbine combusting the reactor gas output and producing a waste heat to preheat methanol upstream of the liquid fuel reactor and wherein the liquid fuel reactor converts the cellulosic biomass and methanol into a liquid fuel and yields a carbon dioxide byproduct, wherein the carbon dioxide byproduct is superheated downstream of the power generating cycle and upstream of the liquid fuel reactor by heat exchange with the preheated methanol.

2. The energy production system according to claim 1 wherein the power generating cycle is further comprised of a supercritical carbon dioxide thermodynamic power generating cycle in thermal communication with the waste heat from the power generating cycle gas turbine.

3. The energy production system according to claim 2 power generating cycle produces a combustion exhaust, and wherein a portion of the combustion exhaust is a carbon dioxide source to the supercritical carbon dioxide thermodynamic power generating cycle.

4. The energy production system according to claim 1 wherein the liquid fuel reactor has a catalyst and wherein the liquid fuel reactor operates above the supercritical temperature and pressure of carbon dioxide.

5. The energy production system according to claim 4 wherein the power generating cycle is a top cycle power generating Brayton cycle that concurrently produces waste heat first to disassociate an organic molecule into syngas as a replacement to the methanol.

6. The energy production system according to claim 5 wherein the top cycle power generating Brayton cycle consumes a fuel that is a byproduct of the liquid fuel reactor.

7. The energy production system according to claim 6 wherein the byproduct of the liquid fuel reactor includes a gas comprising hydrogen and methane.

8. The energy production system according to claim 1 wherein the power generating cycle is further comprised of a steam thermodynamic power generating cycle in a thermal communication with the waste heat from the power generating cycle gas turbine.
