Thermodynamic analysis of ethanol reforming for hydrogen production
Sun, Shaohui; Yan, Wei; Sun, Peiqin; Chen, Junwu - In: Energy 44 (2012) 1, pp. 911-924
This work presents the simulated equilibrium compositions of ethanol steam reforming (SR), partial oxidation (POX) and auto-thermal reforming (ATR) at a large temperature range, steam-to-ethanol and oxygen-to-ethanol molar ratios. The simulation work shows that the moles of hydrogen yield per...

Challenges and strategies for optimization of glycerol steam reforming process
Silva, Joel M.; Soria, M.A.; Madeira, Luis M. - In: Renewable and Sustainable Energy Reviews 42 (2015) C, pp. 1187-1213
The steam reforming of the main biodiesel by-product, glycerol, has been catching up the interest of the scientific community in the last years. The use of glycerol for hydrogen production is an advantageous option not only because glycerol is renewable but also because its use would lead to the...

Co-gasification of glycerol/fat mixtures in a downflow fixed bed reactor: Preliminary results
Almeida, A.; Pilão, R.; Ramalho, E.; Ribeiro, A.; Pinho, C. - In: Energy Reports 6 (2020) 1, pp. 460-465
The aim of this work was to assess the technical viability of glycerol/fat co-gasification. The gasification performance was studied in a downflow fixed bed reactor using steam as oxidizing agent. Tests were performed with a mixture of 10% of fat and 52% of water, and the effect of temperature...

Blue hydrogen as an enabler of green hydrogen: The case of Germany
Dickel, Ralf - 2020
In Germany decarbonization of the electricity sector by fostering renewables and now phasing out coal-fired power is on track to reach the 2050 de-carbonisation targets, while decarbonising non-electric energy consumption is proving to be more difficult. The present discussion of a national...
