Styrene Production By Catalytic Dehydrogenation Of Ethylbenzene As a result of the study of ethylbenzene dehydrogenation to styrene on the α al 2 o 3 support and the [re, w] γ al 2 o 3 (k, ce) α al 2 o 3 catalytic converter in the presence of water vapor taken in the molar ratio of h 2 o ÷ etb = 14 and the raw materials feed space velocity of ∼1.4 h −1, it was found that there is a great catalytic impact of low re and w depositions on the surface. A pseudo homogeneous model based on intrinsic rate equations for dehydrogenation of ethylbenzene to styrene in an adiabatic fixed bed reactor is developed. steam and ethylbenzene are the main reactants with styrene as the desired product, and benzene and toluene as by products.
Styrene Production By Catalytic Dehydrogenation Of Ethylbenzene Catalytic dehydrogenation of ethylbenzene is the main industrial method to produce styrene 1,2, which is a precursor molecule for the synthesis of rubbers and plastics. in practice, the catalytic dehydrogenation process itself is part of a complex reaction network including not only dehydrogenation but also side reactions. atanda and co. Highly selective production of styrene by non oxidative dehydrogenation of ethylbenzene over molybdenum zirconium mixed oxide catalyst in fixed bed reactor: activity, stability and kinetics. catalysis communications 2021 , 154 , 106307. A set of intrinsic rate equations based on the hougen—watson formalism was derived for the dehydrogenation of ethylbenzene into styrene on a commercial potassium promoted iron catalyst. the model discrimination and parameter estimation was based on an extensive set of experiments that were conducted in a tubular reactor. experimental data were obtained for a range of temperatures, space. A particular emphasis is given to the preparation of styrene from ethylbenzene dehydrogenation using co 2 as a soft oxidant because this method consumes co 2 (one of the greenhouse gases) and emerges as a green chemistry process. the detailed mechanism of ethylbenzene dehydrogenation into styrene using co 2 is studied.

At present, the catalytic dehydrogenation process of ethylbenzene accounts for about 90% of the global styrene production. however, it still suffers from challenges including the high feed ratio of steam to ethylbenzene, the limited conversion rate by thermodynamic equilibrium, complicated product separation, etc., which leads to high energy consumption [ 1 ]. The present research group recently investigated a series of iron based fluidizable catalysts aiming superior performance in catalytic dehydrogenation of ethylbenzene to styrene [5], [6], [8], [15], [16]. among those catalysts the fluidizable feo x meso al 2 o 3 catalyst showed with great promise.
