Publication number: 20140283526Abstract: In some implementations, one or more methods can include producing a hydrogen rich fuel gas for a gas turbine ballasted with nitrogen and steam and superheated to a temperature above its dew point. The fuel gas may have a minimal or reduced content of CO2 or fuel components CO and CH4 which contain carbon so that when combusted in a suitable gas turbine there may be minimal or reduced emissions of CO2 to the atmosphere. These example methods may result in a capture of the bulk of the carbon present in the total natural gas feed as CO2 compressed to pipeline delivery pressure for sequestration.Type: ApplicationFiled: June 3, 2014Publication date: September 25, 2014Inventor: Rodney J.

Publication number: 20140262284Abstract: A method and apparatus to form and compress relatively pure carbon dioxide includes a syngas generator which forms syngas and directs it into a combustion chamber where it is combined with oxygen and combusted to form relatively pure carbon dioxide. A first portion of the formed carbon dioxide is directed to a compressor which is powered by an internal combustion engine. A second portion of the formed carbon dioxide is combined with oxygen and used in combination with a carbonaceous fuel to power the internal combustion engine. This produces exhaust gas which is relatively high purity carbon dioxide which is combined with the carbon dioxide formed by combusting the syngas.Type: ApplicationFiled: March 7, 2014Publication date: September 18, 2014Applicant: Enerjetik LLCInventors: JAMES E KLEPPER, Kenneth L.

Publication number: 20140260310Abstract: In various aspects, systems and methods are provided for integrated operation of molten carbonate fuel cells with turbines for power generation. Instead of selecting the operating conditions of a fuel cell to improve or maximize the electrical efficiency of the fuel cell, an excess of reformable fuel can be passed into the anode of the fuel cell to increase the chemical energy output of the fuel cell. The increased chemical energy output can be used for additional power generation, such as by providing fuel for a hydrogen turbine.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Paul J. Berlowitz, Timothy Andrew Barckholtz, Frank H. Hershkowitz, Anita S. Lee

Publication number: 20140260311Abstract: In various aspects, systems and methods are provided for operating a molten carbonate fuel cell assembly at increased power density. This can be accomplished in part by performing an effective amount of an endothermic reaction within the fuel cell stack in an integrated manner. This can allow for increased power density while still maintaining a desired temperature differential within the fuel cell assembly.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Paul J.
