Due to the feasibility of ethanol production in the United States, ethanol has become more attractive as a fuel source and a possible energy carrier within the hydrogen economy. Ethanol can be stored easily in liquid form, and can be internally pre-formed prior to usage in low temperature (200 o C – 400 o C) solid acid and polymer electrolyte membrane fuel cells. However, complete electrochemic...

The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....

A rise in CO2 and other greenhouse gases’ concentration from gas refinery flares and furnaces in the atmosphere causes environmental problems. In this work, a new process was designed to use waste gas (flue gas and flare gas) of a domestic gas refinery to produce pure hydrogen in a membrane reactor. In particular, the process foresees that the energy and CO2 content of flue gas can provide the ...

Abstract: The Thermoselect process is a completely new solid waste treatment process which achieves pollution-free recycling of municipal solid waste and industrial waste by a high temperature gasification and reforming process. The process effectively recovers fuel gas from waste and recycles metal and other byproducts as resources. A stable gas engine power generation system using purified sy...

2. Productivity at this level means that the production costs of H 2 (expressed as the cost in US dollars per joule of calorific value contained in the molecule) are two to three times higher than for natural gas 4,5. However, taking into account the transportation and distribution costs of natural gas, and how pure you want the H 2 to be, the comparative cost of H 2 production can vary. Biomas...

Internally reforming anode supported solid-oxide fuel cells (SOFC) running on humidified CH4 is studied numerically. The computational framework employs detailed multi-step models for heterogeneous chemistry for Ni catalysts. The electrochemistry is implemented using a modified Butler–Volmer setting based on elementary charge transfer kinetics. Transport through the porous matrix is modeled usi...
