✦ Synopsis

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.

The data were used in connection with the transport equations to obtain effectiveness factors, rate constant, activation energy, and reaction order for oxygen concentration.

The necessity of considering thermal effects is exhibited clearly by this system. The maximum temperature rise observed inside the catalyst (33Β°C.) is associated with a 60% increase in utilization factor over the isothermal value.

## Abstract The problem of simultaneous convection, diffusion and reaction inside a porous catalyst slab is considered. A combination of perturbation and integral mathematical techniques are used to derive approximate analytical solutions for the concentration and temperature profiles, as well as f
