CARBOX—a computer programme for the numerical evaluation of equilibria involving CO-CO 2 -H 2 -H 2 O-CH 4 mixtures and non-stoicheiometric oxides and carbides

Abstract

A computer programme (CARBOX) has been written which makes for easier use of existing methods for representing the oxidising, sooting and carburising tendencies of CO–CO₂–H₂–H₂O–CH₄ mixtures in contact with metals or their oxides and carbides; these have previously found only limited application because of the tedious nature of the calculations. The basic equilibrium relationships have been stated in generalised form, so that problems involving equilibrium with non-stoicheiometric compounds can be dealt. with, provided that the relevant free-energy data are available, and a number of different types of solutIOn have been programmed. As a result it is now possible to examine a variety of cases involving conditions not considered by previous workers. Some typical applications are listed.
