Hydrogen from Biogas: Dynamic Modeling of an Integrated Shift Reactor
Chemie Ingenieur Technik, EarlyView.A dynamic, two‐dimensional shift reactor model for the production of hydrogen from biogas is presented. This shift reactor enables the preheating of the biogas feed and, in parallel, reduces fixed‐bed temperatures, resulting in increased hydrogen yields. The model is validated with measurement data from a pilot biogas steam reforming plant.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Effect of cultivation on maize response to nitrogen fertilizer : a thesis presented in partial fulfillment of the requirements for the degree of Master in Applied Science in Soil Science, Institute of Natural Resources, Massey University, Palmerston North, New Zealand [PDF]
, 2000 Continuous cultivation of arable soils results in the decline of 'soil quality' in terms of structural degradation and nutrient depletion. It decreases soil organic matter content, induces the leaching and gaseous losses of N through enhanced ...
