Weekman, V., et al.; ACS Symposium Series; American Chemical Society: Washington, DC, 1978 PREFACE has, as in past symposia, provided an excellent forum for reviewing recent accomplishments in theory and application This international symposium series grew out of the earlier European Symposia on Chemical Reaction Engineering which began in 1957 In 1966, as part of the American Chemical Society Industrial and Engineering Chemistry Division's Summer Symposium series, a meeting was devoted to chemical reaction engineering and kinetics This meeting highlighted the great interest and activity in this field in the United States, and led the organizers to join with the America European Federation of Chemical Engineers in organizing International Symposia on Chemical Reaction Engineering The first symposium was held in Washington in 1970 and was followed by symposia in Amsterdam (1972), Chicago (1974), and Heidelberg (1976) These meetings consistently attract experts in the field who have submitted many more papers than can be accommodated This year was no exception with more than 130 papers being submitted, only 48 of which could be accepted Again, the international flavor was maintained with more than one-half the papers coming from Western Europe, in addition to one each from Russia, Japan, Australia, and Canada While industrial participation was not as extensive as anticipated (30% ), it did show clearly the increasing and productive application of Reaction Engineering tools to industrial problems The meeting format maintained three plenary review lectures each morning and three parallel, original paper sessions in the afternoon The nine plenary review papers are being published in the American Chemical Society Symposium Series as a separate volume We acknowledge financial support from the National Science Foundation, American Chemical Society-Petroleum Research Fund, Shell Oil Co., Mobil Oil Corp., and Exxon Co A V E R N W W E E K M A N , JR D A N Luss Mobile Research Corp Princeton, NJ University of Houston Houston, T X October 1977 xi In Chemical Reaction Engineering—Houston;
