11. External Diffusion Effects on Heteregeneous Reactions
Additional Homework Problems
- CDP11-AA An isomerization reaction that follows
Langmuir-Hinshelwood kinetics is carried out on a monolith catalyst. [2nd Ed. P10-11]
- CDP11-BB A parameter sensitivity analysis is
required for this problem in which an isomerization is carried out over a 20-mesh gauze
screen. [2nd Ed. P10-12]
- CDP11-CC This problem examines the effect on
temperature in a catalyst monolith. [2nd Ed. P10-13]
- CDP11-DB A second-order catalytic reaction is
carried out in a catalyst monolith. [2nd Ed. P10-14]
- CDP11-EC Fracture acidizing is a technique to
increase the productivity of oil wells. Here acid is injected at high pressures to
fracture the rock and form a channel that extends out from the well bore. As the acid
flows through the channel, it etches the sides of the channel to make it larger, and thus
less resistant to the flow of oil. Derive equations for the concentration profile of acid
and the channel width, each as a function of distance from the well bore. [2nd Ed. P10-15]
- CDP11-FC The solid-gas reaction of silicon to form
SiO2 is an important process in microelectronics fabrication. The oxidation
occurs at the Si-SiO2 interface. Derive an equation for the thickness of the
SiO2 layer as a function of time. [2nd Ed. P10-17]
- CDP11-GB Mass transfer limitations in CVD
processing to product material with ferroelectric and piezoelectric properties. [2nd Ed.
P10-6]
- CDP11-HB Calculate multicomponent properties. [2nd
Ed. P10-9]
- CDP11-IB Application of the shrinking core model
to FeS2 rock samples in acid mine drainage. [2nd Ed.
P10-18]
- CDP11-JB Removal of chlorine by adsorption from a packed bed reactor. Vary system parameters to predict their effect on the conversion. [3rd Ed. P11-5B]
- CDP11-KB The reversible reaction A
B is carried out in a PBR. [3rd Ed. P11-6B]
- CDP11-LB Oxidation of ammonia over wire screens. [3rd Ed. P11-7B]
- CDP11-MB Sgt. Ambercromby on the scene again to investigate foul play. [3rd Ed. P11-13B]
