Biogas as hydrogen source for fuel cell applications

The production of pure pressurised hydrogen by the reformer-steam iron process in a fixed bed reactor system

“…The simulation was carried out using the commercial software ASPEN Plus™ -V7.2 (Aspen Technology, Inc.) with the Standard Peng-Robinson equation of state which is suitable for gas processing of hydrocarbons [22,23]. Equilibrium compositions of the steam reforming process as well as methane decomposition were calculated by the minimisation of the Gibbs function using the RGibbs reactor block.…”

Structural, morphological and electrical properties of Ce1−Ru O2−δ (x=0.005–0.02) solid solutions

“…Specially, CeO 2 attracted great attention as an electrolyte of new generation of SOFCs, which are able to operate at relatively low temperatures using a variety of fuels, such as hydrogen, biogas, methane and natural gas [13][14][15][16]. Because of its fluorite type crystal structure, the lattice of CeO 2 is able to accommodate relatively large amount of group IIA or rare earth metal cations (Ca 2 þ , Sr 2 þ , La 3 þ , Nd 3 þ , Sm 3 þ , Eu 3 þ , Gd 3 þ , Dy 3 þ , Ho 3 þ , Er 3 þ , Yb 3 þ Y 3 þ ), which may modify its electrical conductivity [6,7,[17][18][19][20][21][22][23][24][25][26].…”

Combustion and Heat Release Characteristics of Biogas under Hydrogen- and Oxygen-Enriched Condition

“…As an advantageous energy source, biogas is widely considered as a suitable fuel for heating facilities, power generation, and vehicles [8][9][10][11][12][13][14][15]. However, biogas possesses a relatively lower heating value (about 3000-6000 kcal·m −3 ) and lower heat release rate than conventional fuels, which limits the application of biogas in combustion devices.…”
