Task # 4

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 tok '= 7E15 exp (-18000 / T) m3 / (kgcat s). The particles are spherical with a diameter of D = 2 mm and onedensity of 1200 kg / m3.

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?

A packed bed reactor has the reaction A --> B occurring. The rate law is –rA = kCA where k = 15 L/g-min. The superficial gas velocity is 4.8 kg/m2-s with a density of 0.45 kg/m3 and a viscosity of 3.9x10-5 kg/m-s. The porosity, catalyst density, and particle diameter are, respectively, 0.45, 2.2 g/cm3 and 0.255 cm. The cross sectional area of the reactor is 12 cm2. The inlet pressure is 100 kPa. Calculate the conversion ‘X’ when the catalyst...

The gas phase reaction: 2A+B = 3C , is carried out in an isothermal packed bed reactor. The rate is first order with respect to reactants A and B (second order overall) with the rate constant of 14 [liter2 /mole kg of catalyst sec.]. The feed is 50% A, 25 % B and 25 % inert at temperature of 500 K and P = 18 atm and a total flow rate of 20 mole/sec. The exit pressure is measured to...
