PECULIARITIES OF SIMPLE AND COMPLEX CHEMICAL-REACTIONS IN GRAINS OF POROUS CATALYSTS

The kinetics of simple and consecutive-parallel reactions proceeding i n non-isothermal porous catalyst grains of different configurations is considered. Allowance was made for the resistance to the heat-exchang e and mass-transfer between the external grain surface and the reactio n mixture flow. The effect of several parameters on the catalytic perf ormance, along with the problem of ''dead zone'' formation are discuss ed. The optimization conditions of the efficiency factor and selectivi ty are determined as well.
