Optimization of Higher Alkanes Dehydrogenation Process under Conditions of Decreased Hydrogen Containing Gas Flow with Using Mathematical Modeling

The article proposes the way of saving catalyst resource and increasing the efficiency of higher alkanes dehydrogenation process using mathematical model method. The study has indicated, that reducing hydrogen/feedstock molar ratio results in balance shear of alkanes dehydrogenation reaction to alkenes, which is proved by the results of pilot operating of the alkenes production unit at Ltd. KINEF and by the mathematical model calculations. The results of the prediction calculation of optimum process parameters at various hydrogen/feedstock molar ratios are presented.
