In July 1988, a Worldwide Catalysis Seminar was held to mark the 30th anniversary of the Catalysis Society of Japan. After the 9th International Congress on Catalysis in Calgary, about 25 Japanese researchers working on catalysis visited and held seminars in four countries. Each seminar focused on a specific subject, yet also covered a wide range of topics in catalysis, from the fundamental to the industrial stages. This volume, containing the proceedings of this unique event, reflects the successful way in which the seminars provided an opportunity for direct communication and discussion of how best to achieve the successful design of catalysts.
