Natural gas may be used instead of hydrogen as fuel for the molten carbonate fuel cell (MCFC) by steam reforming the natural gas inside the MCFC, using a nickel catalyst (internal reforming). The severe conditions inside the MCFC, however, require that the catalyst has a very high stability. In order to find suitable types of nickel catalysts and to obtain more knowledge about the deactivation ...

Exploiting the greenhouse gas CO2 as raw material could be more advantageous than its long-term storage. For instance, CO2 can be used on large scale for the production of COrich syngas with a H2/CO ratio of unity. Such a syngas can be used for the synthesis of commodity chemicals like aldehydes and ketones obtained through carbonylation of alkenes in hydroformulation and can be produced by CO2...

In an attempt ot develop a one step process for the removal of H2S from sour gas, the engineering consideration were dealt with in two steps. In the first step it was attempted to derive the data required for establishing the design criteria for a pilot plant, by experimenting with a small bench scale.

Direct Reduction processes use gases (CO and H2) for iron reduction production of sponge or direct reduced (DRI). The generation this gas occurs through methane reforming, which can be done in a reformer inside the shaft with as catalyst. latter auto-reforming processes. kinetics steam reforming catalyzed by was studied at temperatures between 875°C 1050°C. Results showed that acts catalyst con...

Hydrogen-rich synthesis gas was produced by pulsed dc plasma submerged into ethanol–water mixtures using an original system with a coaxial geometry. The ignition of the discharge is immediately followed by production of hydrogen and after a short time necessary for filling the outlet tubing a flame can be ignited. No auxiliary gas was used for the reforming process. The synthesis gas containing...

A collaborative effort between industry and government shows progress towards the goal of identifying productive natural fractures in gas reservoirs using seismic methods. Improved geological understanding of mature gas reservoirs in offshore Gulf of Mexico points towards unrecovered resource. A simple new technique to improve primary cement jobs has resulted in a 36 percent decrease in average...
