Kinetic parameter estimation in microbial desulfurization of coal

Desulfurization of Coal

Microbial Desulfurization of Malaysian Coal in Batch Process using Mixed Culture (RESEARCH NOTE)

Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...

Kinetic Parameter Estimation in Oscillatory Biochemical Systems

NABAVI, SEYEDBEHZAD. Kinetic Parameter Estimation in Oscillatory Biochemical Systems. (Under the direction of Cranos M. Williams.) Oscillatory pathways are among the most important classes of biochemical systems with examples such as circadian rhythms and cell cycles. Mathematical modeling of these highly interconnected biochemical networks is needed to meet numerous objectives such as investig...

Coal Desulfurization by Solvent Leaching Methods

Coal desulfurization prior to usage is a preprocessing in order to achieve clean fuel and reduce environmental impacts such as acid rain. Desulfurization of Lakhra (Pakistan) coal was conducted with different solvents. Coal was leached with different solvents like hot water, H2O2/H2SO4 and HNO3. It was found that the effects of the leaching temperature, agitation time and particle size on the r...

Kinetic Parameter Estimation Using Modified Differential Evolution

For the development of mathematical models in chemical engineering, the parameter estimation methods are very important as design, optimization and advanced control of chemical processes depend on values of model parameters obtained from experimental data. Nonlinearity in models makes the estimation of parameter more difficult and more challenging. This paper presents an evolutionary computatio...
