Abstract

The object of the research is multi-stage integrated production of linear alkylbenzenes and linear alkylbenzene sulfonic acid. The established thermodynamic and kinetic laws of the transformations of C9-C14 hydrocarbons and the activity of catalysts used in the synthesis of linear alkylbenzenes provided the creation of mathematical models suitable for optimizing the main stages of the synthesis. the assessment of the full range of nonstationarity factors caused by the deactivation of catalysts was made on the basis of a computational and industrial experiment simulation. the model calculations allowed improving the efficiency of multistage production of alkylbenzene sulfonic acid and to increase the desired product yield from 170 -172 to 174-176 tones/day.
