Falsified Kinetics. The irreversible gas-phase dimerization
is carried out at 8.2 atm in a stirred contained-solids reactor to which only pure A is fed. There are 40 g of catalyst in each of the four spinning baskets. The following runs were carried out at 227°C:
The following experiment was carried out at 237°C:
- (a) What are the apparent reaction order and the apparent activation energy?
- (b) Determine the true reaction order, specific reaction rate, and activation energy.
- (c) Calculate the Thiele modulus and effectiveness factor.
- (d) What pellet diameter should be used to make the catalyst more effective?
- (e) Calculate the rate of reaction on a rotating disk made of the catalytic material when the gas-phase reactant concentration is 0.01 g mol/L and the temperature is 227°C. The disk is flat, nonporous, and 5 cm in diameter.
Additional information:
Effective diffusivity: 0.23 cm2/s Radius of catalyst pellets: 1 cm
Surface area of porous catalyst: 49 m2/g-cat Color of pellets: blushing peach
Density of catalyst pellets: 2.3 g/cm3
