This book is dedicated to the rapidly grown field of microporous ceramic membranes
with separating layers of pore diameter less than 2 nm. In spite of the recent rapid growth
of the research effort directed towards the development of microporous ceramic
membranes the field is still considered to be at its infancy and exhibits a significant future
growth potential. The driving force for these efforts is of course the very promising
opportunities for cost-effective large scale gas separation applications, which can be
classified into two major categories: the "high temperature molecular sieving" and the
"low-temperature reverse molecular sieving" modes of separation techniques.
