Circulating hydrogen-oxygen mixtures were reacted a t atmospheric pressure in a single long porous catalyst cylinder which contained a thermocouple-micromanometer probe. Rate and temperature rise data were obtained at 20", 30Β°, 50", and 60Β°C. in the concentration range 0 to 5% oxygen in hydrogen. T
A chemical reaction in a porous catalyst particle is considered. It is shown that in both the isothermal and non-isothermal cases, with either Dirichlet or third kind boundary conditions, two sequences of functions can be obtained, one of which converges to the maximal solution and the other to the
