Introduction Reforming (i.e., partial oxidation, steam reforming, or autothermal reforming (ATR)) of infrastructure fuels, such as natural gas, liquefied petroleum gas, gasoline, or diesel, is one approach being investigated for distributed H2 production for use with fuel cell systems being developed for automotive and stationary applications. One area of interest is reforming gasoline either o...

A long term pilot scale experiment with steam reforming treatment technology was conducted for volume and weight reduction of uranium contaminated waste tri-n-butyl phosphate/n-dodecane solvent (TBP/dodecane) which was difficult to incinerate. The technology consists of a steam reforming process and a submerged combustion process. In the first process, TBP/dodecane is vaporized and pyrolyzed wi...

High temperature steam gasification/reforming of biomass-methane mixtures was carried out in an indirectly heated entrained flow reactor to analyze the feasibility of controlling the output composition of the major synthesis gas products: H(2), CO, CO(2), CH(4). A 2(3) factorial experimental design was carried out and compared to thermodynamic equilibrium predictions. Experiments demonstrated t...

We examine a H2 PEMFC power generation system composed of three subsystems: fuel reforming, fuel cell stack, and post combustion. The system was simulated and optimized with a fuel cell model integrated within the process flow sheet. We present a case study of the H2 production optimized w.r.t. the CH4 and H2O inlet flow rate and the temperature of steam methane reform reactor. Our objectives a...

Palladium-based catalytic membrane reactors (CMRs) effectively remove H₂ to induce higher conversions in methane steam reforming (MSR) and water-gas-shift reactions (WGS). Within such a context, this work evaluates the technical performance of a novel CMR, which utilizes two catalysts in series, rather than one. In the process system under consideration, the first catalyst, confined within the ...

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...
