Efficient Performance of the Methane-Carbon Dioxide Reform Process in a Fluidized Bed Reactor

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...

THE ANAEROBIC DIGESTION PROCESS IN A FLUIDIZED BED REACTOR The anaerobic digestion is an efficient process to treat effluents

In this article, a Takagi-Sugeno fuzzy observer for the anaerobic digestion process in a fluidized bed reactor is proposed. First, a general explanation of this bioprocess is introduced. A model of the system discretized in the space by the orthogonal collocation method is presented. This model is analyzed locally to prove properties of stability and observability. Then, the design of the fuzzy...

Unsteady-State Modeling of the Fluidized Bed Polyethylene 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...

Pyrolysis of Softwood Carbohydrates in a Fluidized Bed Reactor

In the present work pyrolysis of pure pine wood and softwood carbohydrates, namely cellulose and galactoglucomannan (the major hemicellulose in coniferous wood), was conducted in a batch mode operated fluidized bed reactor. Temperature ramping (5 degrees C/min) was applied to the heating until a reactor temperature of 460 degrees C was reached. Thereafter the temperature was kept until the rele...
