Processmg and Utdtsatlon of Hqh-Sulphur Coals V editedby B K Parekh and J G Groppo, Coal Science and Technology 21, Elsevler, 1993, ISBN O-444-81476-0, pnce US$4OO, x11+632 pp There 1s no doubt that the utlhsatlon of high sulphur coals IS an Important issue facing a number of countries The tighter environmental regulations being imposed around the world have resulted m much research, development and demonstration of technical advances over a number of years for reducing sulphur dioxide emlsslons Many countries are involved, the geographical spread 1s wide Much of the technical progress has been presented in papers to relevant technical Journals and conferences For example, this volume contains almost 50 papers which were presented at the Fifth International Conference on Processing and Utdlsatlon of High-Sulphur Coals, October 1993, Lexmgton, KT, USA Papers from earlier conferences in this series have already appeared m previous volumes of the Science and Technology Coal series published by Elsevler, namely Volumes 9, 16 and 18 Being a USA conference, the majonty of the papers are from that country, but papers have been contributed from several others, including China, Canada, Italy, Turkey and the UK The SubJect areas covered are quite comprehensive The book starts with coal characterlsatlon papers and then proceeds with papers on physical, chemical and blologlcal desulphunsatlon Two parts are devoted to sulphur control during and post combustion, with a final section compnslng an assortment of papers Inevitably, because of the nature of the pubhcatlon, the assembled papers cannot be regarded as giving a particularly comprehensive insight mto the work being undertaken worldwide m desulphunsatlon Rather, it features a collection of papers with a USA bias which happened to be presented at a particular conference This 1s reflected m the lack of conslstency m the typeface used for the papers Nevertheless, the book has ment It does give the opportunity to those who were unable to attend the conference to purchase a copy of the proceedings and to consult the papers to gain an insight into some of the current research, development and demonstration activities Thus, much of its value lies in its prompt pubhcatlon It 1s not practical in a short review to give the reader much insight into the vanety of the papers presented The majonty Elsevler Science S A

Rapid developments m the synthesis and design of polymeric membranes have enabled apphcatlons m processes, such as reverse osmosis, electrodlalysu, ultrafiltratron, pervaporatlon, gas separation, hemodlalysls, controlled release of drugs and genetic engineering This multi-authored book, edited by Professors Osada and Nakagawa, with all the authors from Japan, 1s a timely mtroductlon which gives a comprehensive treatment of basic pnnclples and advances m membrane science and technology It covers the methods, structures, properties, and apphcatlons of polymer-based membranes The SubJect is divided into four parts, each of which will be reviewed separately The Physrcal Chemistry of Membranes A clear description of structures of membranes as (1) dense, (11) porous and (m) composite (both asymmetric and Langmuir-Blodgett) and the factors influencing then functions, such as sorption, dlffuslvlty, and permeablhty of small molecules is given by Professor TsuJita m Part I Effects of cross-linking and graftmg, crystalhtes, annealing and stretchmg and additives on membrane functions are described quahtatlvely A ngorous treatment of non-eqmhbnum thermodynamrcs of non-charged and charged membranes and sorption, diffusion and permeation phenomena are also presented Sorption properties for Henry’s law mode and Lang-
