Modeling of Transalkylation Stage of Ethylbenzene Manufacturing with Zeolite-catalysts

The analysis of industrial transalkylation reactor revealed regularities of catalyst activity and stability changes during its operation at change of basic technological parameters. A result of experimental data analysis, a list of possible reactions of transalkylation stage of ethylbenzene manufacturing zeolite-catalyst technology was developed. Values of Gibbs energies for change targets and adverse reactions, which were calculated with use of quantum chemistry methods, confirmed their thermodynamic probability at process conditions. The calculation results formed the basis of transalkylation process reaction network, needed to develop a mathematical model of ethylbenzene manufacturing zeolite-catalyst industrial technology.
