New Findings from Chalmers University of Technology in the Area of Chemical Engineering Reported (Chromatographic separation of wood model constituents-Mathematical modeling and parameter estimation)

By a News Reporter-Staff News Editor at Journal of Engineering -- Data detailed on Chemical Engineering have been presented. According to news reporting originating from Gothenburg, Sweden, by VerticalNews correspondents, research stated, "A mathematical model of the hydrophobic adsorption chromatographic separation of wood model constituents has been developed. Veratryl alcohol was selected to illustrate a lignin molecule and salicin was selected to illustrate a lignin-carbohydrate complex."

Our news editors obtained a quote from the research from the Chalmers University of Technology, "A variety of available experimental methods in combination with parameter fitting was used to estimate the parameters of packed bed porosity, axial dispersion, film mass transfer, diffusivities and adsorption equilibria with a phenylic silica stationary phase. The model was verified to simulate the separation to within an accuracy of 95%."

According to the news editors, the research concluded: "The model was,however, unable to predict the phenomenon of elution curve fronting, caused by the channeling of the packed bed."
