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

The kinetics of simple and consecutive-parallel reactions proceeding in non-isothermal porous catalyst grains of different configurations is considered. Allowance was made for the resistance to the heat-exchange and mass-transfer between the external grain surface and the reaction mixture flow. The effect of several parameters on the catalytic performance, along with the problem of ''dead zone'' formation are discussed. The optimization conditions of the efficiency factor and selectivity are determined as well.
