This work was funded by the Hydrogen Program Office of the U.S. Department of Energy under Grant No. DE-FG01-99EE35099 and represents the second task of three to be completed under this contract. The first task presented a broad overview of the costs for creating infrastructures to supply direct hydrogen, methanol, and gasoline to support fuel cell vehicles (FCV’s). A conclusion of the report r...

Hydrogen production is critical to many modern chemical processes – ammonia synthesis, petroleum refining, direct reduction of iron, and more. Conventional approaches hydrogen manufacture include steam methane reforming autothermal reforming, which today account for the lion's share generation. Without CO2 capture, these emit about 8.7 kg each H2 produced. In this study, a molten carbonate fuel...

A process scheme based on a series of fixed-bed reactors is presented as a possible alternative for carrying out the chemical looping combustion of methane at high pressure with ilmenite as oxygen carrier. The oxygen carrier is stationary and it is alternately exposed to reducing and oxidizing atmospheres by means of the periodic switching of the gas feeds (i.e., methane and air, respectively)....
