Determination of the Deactivation Model of Iron-potassium/γ-Al2O3 Catalyst in a Fixed Bed Reactor
Catalyst activity and performance are the most important factors for selecting a catalyst in different processes. The Fischer-Tropsch synthesis is a very important synthesis that extensive action has been taken place to increase the activity of its catalysts in the recent century. Deactivation of the catalysts of the process is influenced by many factors, among which coking and sintering have c...
متن کاملDetermination of the Product Selectivity Model from the Fischer Tropsch Synthesis in a Fixed Bed Reactor
The Fischer-Tropsch synthesis is a catalytic process that can produce a fuel similar to fossil fuels by using primary sources such as agricultural waste and carbon sources that can convert into synthesis gas by superheated steam. All fuel derivatives can be supplied through the Fischer-Tropsch reaction. The synthesis produces a variety of hydrocarbons via parallel and sequential reactions. Howe...
متن کاملDynamic Simulation and Sensivity Analysis of Fluidized Bed Methanol Reactor with Deactivated Catalyst
Frequently the activity of fresh catalyst changes with time in use. The decrease or increases of the catalyst activity with time during the course of reaction forces the system to an unsteady state operation ([1], [2], [3], [4] and [5]). One of these catalysts is the copper/zinc oxide catalyst, which is industrially used for methanol production. The activity of copper/zinc oxide catalyst declin...
متن کاملThe Effect of Coking on Kinetics of HDS Reaction under Steady and Transient States
A study was made of the coking of a commercial fresh sulfide Ni-Mo/Al2O3 catalyst in a fixed-bed reactor. The catalyst was coked using different coke precursors in the gas oil under accelerated conditions at temperatures of 400 to 450°C to yield different deactivated catalysts containing 2-20 wt% C. Two cases were studied; crushed catalyst without diffusional ...
متن کاملComments on the behaviour of a fixed-bed reactor
Dear Sirs, In a recent series co-workers (see e.g. of papers by Morbidelli and Varma and Morbidelli and Varma 1986a; Morbidelli et al., 1986h Lee and Varma, 1987, 1988; Bauman and Varma 1990), the multiplicity behaviour of a fixed bed reactor is discussed. The basis for this analysis was given by Morbidelli and Varma (1986a) and Morbid& et al. (1986b), where the authors devote many columns to m...
