Catalysis: Significance in Industry and Relevance in Vladimir Haensel Consultant Universal Oil Products Professor of Chemical Engineering University of Massachusetts, Amherst, MA
Abstract The industrial use of catalysis is very extensive, as witnessed by nearly 20% of the U S . gross national product (GNP) being generated through the use of catalysis. The recent trends in energy conversion systems toward so-called synfuels and extensive use of catalysis for emissions control have created further challenges for catalysis.

The real question is whether or not this evolutionary orocess is sufficient for our future needs: or. bv shanine . chemistry curricula, can we further enhance the preparation of the future workers in industrial catalvsis? Furthermore. what is the importance of a general knowledge about catalysis for those chemists who will not work in industrial catalysis, or for those going into chemistry-related careers? This presentation discusses the issues, and offers a number of observations and suggestions. ~~

control. It is entering the food area. As we become more and more energy conscious, the more we tend to turn to catalysis to do things more selectively and more economically. This did not happen overnight. Catalysis has been growing rapidly over the last 50 years. Why have we not included catalysis in our curricula? Is it because we make up our notes from books written by people who made it up from notes and hooks from years ago? Or is it because, in our attempts to instill fundamentals, we fail to mention applied chemistry? Even worse, do we look with disdain upon industrial chemistry as being something impure and uninteresting or merely a collection of pots and pans where some new chemical is cauldroned out to the public?
