✦ Synopsis

The case of double parallel reaction scheme taking place in a porous catalytic pellet is analyzed. Effectiveness factor expressions for both reactions are derived after matching asymptotic solutions strictly valid for small and lame values of the Thiele moduli It is assumed that th: kinetics of both reactions follow a general irreversible power law model, that isothermal conditions prevail and that external mass transfer, resistences are negligible.

Approximate results in terms of effectiveness factors comoare fairly well with exact results obtained bv nu&&cal integration of the differential equations. circumstances is around 3%.
