Modification of Langmuir isotherm for the adsorption of asphaltene or resin onto calcite mineral surface: Comparison of linear and non-linear methods

摘要: In this paper, the Langmuir isotherm, originally derived for adsorption of three samples asphaltenes and one sample resin onto calcite, was modified to fit isotherm. The isotherm parameters obtained from four linear equations using different method. aim modification is based on fact that direct application often leads poor data fitting. present communication, it shown level fitting can be improved by a simple introducing concentration dependent factor, X. Four Modified linearized models non-linear model discussed in their coefficients were estimated. study, study model, genetic algorithm used. A procedure utilized optimize constants more accurate estimation set parameters. results demonstrate best algorithm. Furthermore, found among mentioned oil, filtered shale oil follows multilayer
