A laboratory scale packed bed reactor (PBR) with catalytic particles is used to make experimentswith an irreversible 1st order gas phase reaction A → product at 500 K. The rate constant forthe reaction, determined by conditions where mass transport resistance could be neglected, is found to k '= 1,6237 m3/kcat S . The particles are spherical with a diameter of D = 2 mm and onedensity of 1200 kg / m3.

Radius R=1x10-3

Thiele modul Ø=44,141

4.2

The product formed by the reaction condenses immediately and is thus not present in itthe gas phase. How much catalyst mass W must be used in PBR to achieve a conversion rateX of A of 75% if the feed flow consists of 50% A and 50% inert I and the volume flow is 0.01 m3 / s?
