Analysis Of Gauze Reactor Modeling

1. Introduction: Gauze reactors are the emerging reactors to stabilize the utilisation of catalytic material and increase the rate of reaction. The word Gauze is originated from a French word “gaze”, which means a thin fabricated wired structure. In ancient days gauzes were specifically used in weaving silk clothes. Its trend has been rapidly increased in the present world where they are used for different aspects such as pharmaceutical industries, oxidation purposes, including gauze sponges for medical purposes (medical dressing). Concerning good efficiency and low time consumption, most chemical industries perform reactions under catalytic actions. Yet there are some fast occurring reactions which are controlled by external mass

The gauze reactor consists of a series of wire screens, stacked one on top of the other. This arrangement serves as a catalyst bed where reactants pass over series of screens. The merit in this schematic reactor lies in imparting catalyst in shape of thin wires instead of porous media. Porous catalyst media become ineffective under certain circumstances like external mass transfer, relative high temperature rise etc. but gauzes are effective even at those conditions. This paper strives to analyse the Gauze reactor modelling and its industrial applications vitally catalytic partial oxidation of methane (for production of synthetic gas, other fuel sources) and oxidation of ammonia (for production of

DETCHEM stands for “DETailed CHEMistry”. It is a collection of software tools of FORTRAN specifically designed for modelling and simulations of reacting flows. It is used for calculation of reaction rates, species transport, thermodynamic properties (library modules). Nowadays DETCHEM is widely used in academics, research area as well as in industries. The potential of this software lies in the use of elementary step reaction mechanism in modelling surfaces and gas – phase chemistry. In many applications, the huge number of chemical species and reactions makes the complete system simulation a prohibitive task for commercial species and are mostly written for general purpose applications. DETCHEM uses numerical algorithms for solution of huge and complex equation systems arising from physic – chemical models for simulation of special applications. DETCHEM has been appled to simulations in fields like catalytic reactors, catalytic combustion, automotive catalytic converters, micro – reactors, solid oxide fuel cells, chemical vapour deposition etc. DETCHEM consists of DETCHEMG and DETCHEMS. DETCHEMG includes pre-processor GASINP and models gas phase chemistry while DETCHEMS includes pre-processor SURFINP, models the surface (heterogeneous) chemistry. It is also designed to be coupled to the open source CFD software package with CFD codes such as
