2003). Fixed bed reactor is well known technology, whose improvement is based on the modification of catalyst rather than design of a reactor. Cruz-Lopez et al. (2005) investigated the selective oxidation of n-butane in a membrane reactor. They used a high concentration of n-butane. Fixed bed reactor is limited to processes with a First published on 17th August 2012. The oxidative dehydrogenation of ethane to ethylene was studied using a MoO 3 based catalyst supported on γ-alumina spheres. The measurement of species and temperature profiles through a fixed bed reactor shows for the first time the reaction pathways inside the catalyst bed directly. Oxidative dehydrogenation of ethane to ethylene and water occurs on the ...

In this study, we have developed a relatively simple mathematical model capable of both simulating the synthesis of maleic anhydride from n-butane in industrial fixed-bed reactor and determining the influences of inlet process parameters on reactor performance. Ten kinetic models were used, and each of them was used in combination with a simplified reactor model.

behavior of a Mo-V-Nb-Te-O catalyst in a single-tube wall-cooled fixed-bed reactor for the ODH-Et. A 2D pseudo-homogeneous fixed-bed reactor model that couples heat and mass transport phenomena to kinetics was proposed to describe the ODH-Et on a Mo-V-Nb-Te-O catalyst. The effective heat and mass transport parameters were obtained from a previous ethylbenzene dehydrogenation reactor using several kinetic models. The optimum operating conditions are explored for one and two-bed reactor configurations by using two industrial catalyst systems. This model was then used to locate the optimum inlet temperature and steam to oil ratio for a
