Dynamics of Temperature and Concentration on Oxidation Reaction Using Reverse Flow Reactor With Periodic Feed Gas Like Square Wave Function: a Numerical Approach

Abstract

Dynamics of oxidation reaction using reverse flow reactor (RFR) are given by a set of convection - diffusion equations that containing the non-linear term corresponding to the reaction rate and provided with certain initial and boundary conditions. In this paper, we investigate the dynamic profiles of temperature and feed concentration on oxidation process using numerical simulation approach. Here we assume the process satisfies 1-D pseudo-homogeneous model and the feed gas form is square wave function. Several different operation parameters have simulated to see the influence towards temperature and feed concentration profile. The results show that period function, small switching time, medium gas velocity and small specific reactor wall surface will make the reactor operated longer.
