A method for the production of clean hydrogen is demonstrated. The process consists of two steps involving the decomposition of methane to CO-free hydrogen and surface carbon in the first step followed by steam gasification of this surface carbon in the second step. This process can be operated in cycles and could be an excellent hydrogen source for fuel cells and other devices or processes req...

A membrane reactor is a reaction system that provides higher productivity and lower separation cost in chemical reaction processes. In this paper, packed bed catalytic membrane reactor with palladium membrane for methane steam reforming was analyzed both experimentally and numerically. The numerical model consists of a full set of partial differential equations derived from conservation of mass...

This study investigates the feasibility of electricity production in a solid oxide fuel cell using methane recovered from groundwater as fuel. Methane must be removed for drinking water to, amongst others, avoid bacterial regrowth. Instead releasing to atmosphere or converting it carbon dioxide by flaring, can also vacuum stripping and served However, electrical efficiency currently used combus...

Introduction Hydrogen as a fuel has recently been an important issue due to developments in fuel cell technology. Hydrogen production from sustainable sources, e.g. biomass, is gaining attention for a CO2 neutral energy supply. Recent developments in flash pyrolysis technologies make it possible to convert lignocellulosic biomass efficiently to a bio-oil, which is easier for handling and transp...

A detailed model is presented for the analysis of temperature, species concentration, and current density profiles as well as the efficiency and power density of a planar solid oxide fuel cell at direct internal reforming condition. The model describes the interactions of mass transport, heat transport, heterogeneous chemistry, and electrochemistry. The heterogeneous chemistry model for the cat...

Novel NiO/GDC (Gadolinium-doped Ceria) cermet catalysts were developed by the Weak Acid Resin (WAR) method using an ion exchange resin template. In addition, the specific surface area of these tunable materials was enhanced by NiO partial dissolution in aqueous acid solution. The whole procedure highly improved the micro-structural properties of these materials compared to previous studies. Cat...

The present review focuses on the current progress harnessing potential of hydrogen production by Methane Steam Reforming (MSR). First, based prominent literature in last few years, overall research efforts using different feed stocks like ethanol, ammonia, glycerol, methanol and methane is presented. presented data reactor type, operating conditions, catalyst used yield to provide a general ov...
