SOFC Running on Steam Reforming of Biogas: External and Internal Reforming

Chemical Engineering Transactions, 2016
In this work, two approaches of SOFC operation fuelled by biogas are considered: one where the endothermic steam reforming and electrochemical reaction are operated in different units (external reforming SOFC) and another where biogas is introduced to ...

Numerical Investigation of the Effects of Steam Mole Fraction and the Inlet Velocity of Reforming Reactants on an Industrial-Scale Steam Methane Reformer

Energies, 2018
Steam methane reforming (SMR) is the most common commercial method of industrial hydrogen production. Control of the catalyst tube temperature is a fundamental demand of the reformer design because the tube temperature must be maintained within a range ...

Production of hydrogen by unmixed steam reforming of methane [PDF]

, 2008
Unmixed steam reforming is an alternative method of catalytic steam reforming that uses separate air and fuel–steam feeds, producing a reformate high in H2 content using a single reactor and a variety of fuels. It claims insensitivity to carbon formation

Removal of Tar from Biomass Gasification Process by Steam Reforming over Nickel Catalysts

Chemical Engineering Transactions, 2014
Tar steam reforming (TSR) is a very attractive technique for tar removal. It converts high molecular weight hydrocarbons of tar into smaller gas products including H2, CH4, CO and CO2. Preliminary research focuses on simulation of tar steam reforming. It

Steam reforming on transition-metal carbides from density-functional theory [PDF]

, 2009
A screening study of the steam reforming reaction (CH_4 + H_2O -> CO + 3H_2) on early transition-metal carbides (TMC's) is performed by means of density-functional theory calculations. The set of considered surfaces includes the alpha-Mo_2C(100) surfaces,
