What You Need to Know

Catalytic distillation is a branch of reactive distillation which combines the processes of distillation and catalysis to selectively separate mixtures within solutions. Its main function is to maximize the yield of catalytic organic reactions, such as the refining of gasoline. The earliest case of catalytic distillation was thought to have dated back to 1966; however, the idea was officially patented in 1980 by Lawrence A. Smith, Jr. The process is currently used to purify gasoline, extract rubber, and form plastics.

Steps

  1. 1.

    Petrochemical flavor extraction (Industrial food labs): Isolating synthetic flavor compounds

  2. 2.

    Biofuel alcohol purification (Brazilian ethanol industry): Producing food-grade ethanol

  3. 3.

    Essential oil concentration (French perfumery): Creating food-grade aromatics

Common Mistakes

Catalyst poisoning

Cause: Impurities in feedstock

Fix: Pre-feedstock purification

Flooding

Cause: Excessive vapor velocity

Fix: Flow rate adjustment
