Computer simulation of the steamgraphite reaction under isothermal and steadystate conditions
Abstract
A mathematical model was formulated to describe the isothermal, steadystate diffusion and reaction of steam in a graphite matrix. A generalized LangmuirHinshelwood equation was used to represent the steamgraphite reaction rate. The model also includes diffusion in the gas phase adjacent to the graphite matrix. A computer program, written to numerically integrate the resulting differential equations, is described. The coupled nonlinear differential equations in the graphite phase are solved using the IBM continuous system modeling program. Classical finite difference techniques were used for the gasphase calculations. An iterative procedure is required to couple the two sets of calculations. Several sample problems are presented to demonstrate the utility of the model.
