Hydrothermal phase transformation of hematite to magnetite
Different phases of iron oxide were obtained by hydrothermal treatment of ferric solution at 200°C with the addition of either KOH, ethylenediamine (EDA), or KOH and EDA into the reaction system. As usually observed, the α-Fe2O3 hexagonal plates and hexagonal bipyramids were obtained for reaction with KOH and EDA, respectively. When both KOH and EDA were added into the reaction system, we obser...
متن کاملAccelerated Weathering of Fluidized Bed Steam Reformation Material Under Hydraulically Unsaturated Conditions
To predict the long-term fate of lowand high-level waste forms in the subsurface over geologic time scales, it is important to understand the behavior of the corroding waste forms under conditions that closely mimic to the open flow and transport properties of a subsurface repository. Fluidized bed steam reformation (FBSR), a supplemental treatment technology option, is being considered as a wa...
متن کاملEmergent Behavior in a Low-Order Fluidized-Bed Bubble Model
Low-order models are becoming increasingly useful for simulating the complex collective behavior arising in large dynamical systems. Modeling of traffic flow and the behavior of biological systems such as ant colonies and bird flocks are commonly referenced examples of this new approach. We have explored the application of this type of model to describe the dynamics of voids in bubbling fluidiz...
متن کاملHydrodynamic Behavior of Particles in a Jet Flow of a Gas Fluidized Bed
Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...
متن کاملAttachment Behavior of Shewanella putrefaciens onto Magnetite under Aerobic and Anaerobic Conditions
In this study, batch experiments were used to characterize attachment behavior of Shewanella putrefaciens strain 200R to ferrihydrite and magnetite. Attachment was quantified in batch experiments with a 0.01 M NaNO3 solution as a function of pH (ranging from 3 to 10), sorbed anion (PO3− 4 ), and growth conditions (aerobic vs. anaerobic). Electrophoretic mobility data was collected for S. putref...
