Additional Homework Problems

  1. CDP15-AB Determine the catalyst size that gives the highest conversion in a packed bed reactor.
Slurry Reactors
  1. CDP15-BB Hydrogenation of methyl linoleate - comparing catalyst. [3rd Ed.P12-19B]
  2. CDP15-CB Hydrogenation of methyl linoleate. Find the rate limiting step. [3rd Ed. P12-20B]
  3. CDP15-DB Hydrogenation of 2-butyne-1,4-diol to butenediol. Calculate percent resistance of total of each for each step and the conversion. [3rd Ed. P12-21]
CVD Boat Reactor
  1. CDP15-ED Determine the temperature profiles to achieve a uniform thickness. [2nd Ed. P11-18]
  2. CDP15-FB Explain how varying a number of the parameters in the CVD boat reactor will affect the wafer shape. [2nd Ed. P11-19]
  3. CDP15-GB Determine the wafer shape in a CVD boat reactor for a series of operating conditions. [2nd Ed. P11-20]
  4. CDP15-HC Model the buildup of a silicon wafer on parallel sheets. [2nd Ed. P11-21]
  5. CDP15-IC Rework CVD boat reactor accounting for the reaction: SiH4SiH2 + H2 [2nd Ed. P11-22]
Trickle Bed Reactors
  1. CDP15-JB Hydrogenation of an unsaturated organic is carried out in a trickle bed reactor. [2nd Ed. P12-7]
  2. CDP15-KB The oxidation of ethanol is carried out in a trickle bed reactor. [2nd Ed. P12-9]
  3. CDP15-LC The hydrogenation of aromatics in a napthenic lube oil distillate takes place in a trickle bed reactor. [2nd Ed. P12-8]
Fluidized Bed Reactors
  1. CDP15-MC Reconsider example problem 12-2, using the correlations of C. Chavarie and J. R. Grace [Ind. Engrg Chem. Fundamentals, Vol. 14. No. 2 pp. 75-79 (1975)]
  2. CDP15-NA What would happen if the temperature were increased from 273°K to 546°K.
  3. CDP15-OC At the very top of the column, what is the rate of reaction in the emulsion phase in [gmole/(cm3 of bubble)(s)] as predicted by the Kunii-Levenspiel model?
  4. CDP15-PB When a fluidized column is operated at a superficial velocity of 10 cm/sec which is 5 times the minimum fluidization velocity, it was found the bubble size at the mid-point in the column was 10 cm and that bubbles occupied exactly 10.6% of the column.
  5. CDP15-QB The irreversible gas phase isomerization reactionimage 12eq13.gif
  6. CDP15-RB When operated at twice the minimum fluidization velocity 86.5% conversion is realized in a fluidized bed reactor which has aof 0.5. It is proposed to increase the pressure from 1 atm. to 4.0 atm. and decrease the temperature from 427°C to 227°C.
  7. CDP15-SB The irreversible catalytic isomerization - Comprehensive Problem
  8. CDP15-TB Using tracer studies to characterize fluidized bed reactors.
  9. CDP15-U Using values of the minimum fluidization velocity provided by Kurian and Raja Rao (Ind. J. of Tech., 8, 275 (1970)).
