Sorption of Hydrogen Chloridein The Fluidized Bed Reactor

Decomposition of hydrogen peroxide in a catalytic fluidized-bed reactor

The decomposition of H2O2 by a novel supported g-FeOOH catalyst was performed in a continuous fluidized-bed reactor. This catalyst has been successfully used in the treatment of organic contaminants with H2O2 in our previous work. In this study, we attempted to determine the effects of pH, H2O2 concentration, and catalyst concentration on the decomposition of H2O2. An approach, we regarded this...

Control of a Fluidized Bed Polyethylene Reactor

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...

Enhancement of Hydrogen and Methanol Production using a Double Fluidized-bed Two Membranes Reactor

Nowadays, hydrogen and methanol are attractive prospects because of lower emission compared to the other energy sources and their special application in fuel cell technology, which are now widely regarded as key energy solution for the 21st century. These two chemicals also can be utilized in transportation, distributed heat and power generation and energy storage systems. In this study, a nove...

Improvement of Methanol Synthesis Process through a Novel Sorption-Enhanced Fluidized-bed Reactor, Part I: Mathematical Modeling

In the first part of two section paper, a mathematical model of the fluidized bed reactor in the presence of in-situ water adsorbent for methanol synthesis is assessed. The bubbling two-phase regime is applied to model the fluidization concept. The binary adsorbent and catalyst particles system can be separated from each other based on their density difference. The heavy catalyst particles tend...
