Abstract:
Weekman and Gorring [2] considered the problem of the influence of the Stefan flow in a catalyst grain for mth order gas-phase chemical reaction A → nB. Special numerical methods were used to solve the problem. This paper proposes a simple method for solving the problem of a first-order gas-phase chemical reaction A → 2B using the Mathcad program. As an illustration of the method, the profiles of dimensionless reagent concentration and gas velocity of the Stefan flow at the Thiele parameter ψ = 1 and the molar fraction of reagent A outside the grain θ = 1, the dependence of the catalyst effectiveness factor on the parameters ψ and θ in the ranges ψ = 0.1–10 and θ = 0.1–1, and the dependence of a ratio between the catalyst effectiveness factor at θ = 1 and an analogous parameter in the absence of the Stefan flow on the Thiele parameter were calculated.
