Abstract
A chemical processing apparatus that utilizes a ceramic media sintered at a lower temperature than the apparatus' maximum exposure temperature is described. The media's physical and chemical properties may contribute to its thermal stability when exposed to temperatures that exceed the media's sintering temperature by at least 50° C.
Claims16
A chemical processing apparatus comprising a plurality of ceramic media formed at a sintering temperature, said media are physically distinct and readily separable from one another after thermal cycling in the apparatus from a first temperature that is less than the media's sintering temperature to a second temperature which is at least 50° C. higher than the media's sintering temperature and then back to the first temperature.
