Abstract:

Background and Objectives: SO2 pollution has become a serious concern. The aim of this study is SO2 removal from JP-4 fuel combustion. Materials and Methods: Experiments were performed by thermogravimetric analysis at different temperatures and various SO2 concentration. Kinetic study of non-catalytic gas-solid reaction was performed using mathematical modeling based on random pore model. Results: The pore size distribution curve was obtained. The structural parameters of the random pore model were measured as r=1.92×10-5, ε0=0.64, S0=1.27×106 and ψ=3.81. Thermogravimetry diagram and conversion-time curves were extracted. Fractional reaction modeling is obtained based on gas reactant. Conclusion: The obtained kinetic parameters can be used to design flue gas desulfurization systems at low temperatures.

Experimental Investigation and Modeling of Carbon Dioxide Adsorption from Model Flue gas

In this work, the adsorption of carbon dioxide from model flue gas on different adsorbents has been investigated. Using simplified modeling, parameters such as the total mass transfer coefficient and the effective diffusivity have been determined. Experiments were carried out in two sections: firstly, adsorption of pure carbon dioxide on different adsorbents was measured at pressures ranging fr...

Study and Kinetic Modeling of Direct Sulfation of Iranian Limestones by Sulfur Dioxide at High CO2 Partial Pressure

The direct sulfation of three high purity Iranian limestones and one precipitated calcium carbonate from different sources, containing more than 97 % CaCO3, were studied in a specially designed fixed bed reactor under atmospheric pressure, in the presence of excess CO2 to prevent decomposition of CaCO3. Experiments were carried out over a range of particle s...
