Description

Catalytic distillation: a Distillation culinary technique.

Technical

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.
