Ceramic Membranes for Separation and Reaction (eBook, PDF)

• Format: PDF

Produktbeschreibung

Ceramic Membranes for Reaction and Separation is the first single-authored guide to the developing area of ceramic membranes. Starting by documenting established procedures of ceramic membrane preparation and characterization, this title then focuses on gas separation. The final chapter covers ceramic membrane reactors;- as distributors and separators, and general engineering considerations. * Chapters include key examples to illustrate membrane synthesis, characterisation and applications in industry. * Theoretical principles, advantages and disadvantages of using ceramic membranes under the various conditions are discussed where applicable.
