These new developments and other changes and approaches related to polymerization are noted in Chapters 11 and I hope the new additions that I felt necessary for updating this book are satisfactory to the readers. A water soluble cobalt cluster can effectively hydroformylate higher olefins in a two-phase system using polyethylene glycol as the polar medium. Thus, lyophilic products could be easily separated from the catalyst in the aqueous phase. This problem has successfully been solved for the oxo reaction by using rhodium modified with triphenylphosphine ligands that are water soluble. Homogeneous catalysts, on the other hand, are normally more selective and operate under milder conditions than heteroge- neous types, but lack the simplicity and ease of product separation. Heterogeneous catalysts are more commonly used due to the ease of separating the products. These could be used as feedstocks for petrochemicals as indicated in Chapter 4. Fluid catalytic cracking FCC is also used to supplement the demand for these light olefins.Ī new process that produces a higher percentage of light olefins than FCC is deep catalytic cracking DCCand it is described in Chapter 3. The main route for producing ethylene and propylene is steam cracking, which is an energy extensive process. This is primarily achieved by the search for new cata- lysts that are active and selective. Such growth necessitates much work be invested to improve processing technique and catalyst design and ensure good product qualities. The petrochemical industry is a huge field that encompasses many commercial chemicals and polymers. Although the basic concept and the arrangement of the chapters is this second edition are the same as the first, this new edition includes many minor additions and updates related to the advances in processing and catalysis. To enable the readers to follow the flow of the reactants and products, the processes were illustrated with simplified flow diagrams. It reviewed the mechanisms of many reactions as well as the operational parameters temperature, pressure, residence times, etc. This book, or parts thereof, may not be reproduced in any form without permission of the publisher.
