Although halons (brominated or chlorinated fluorocarbons) are widely used as fire suppressants and foaming agents, they also contribute to stratospheric ozone depletion. However, halons are potentially valuable chemicals that should not be destroyed, but rather converted to reusable chemicals, says Bogdan Dlugogorski, professor of chemical engineering in the school of...

Rigorous temperature control is required for performing selective catalytic reactions, such as hydrogenation and oxidation (ethylene oxide production, for example), and in reactions where the chemical equilibrium is strongly temperature dependent (Claus sulfur recovery or the CO-shift reaction, for example). Up to now, catalyst-filled, straight-tube reactors have typically been used for such reactions. But...
