The Catalytic Reaction Engineering toward Green Chemical Processes Project was undertaken between 2001 and 2003, funded under the Scientific Research in Priority Areas Program of the Ministry of Education, Culture, Sports, Science and Technology of Japan. The representative of the project is Prof. Hattori of Nagoya University. This research project was aimed at establishing the hybrid field of catalytic reaction engineering to bridge the large gap between nano-scale catalytic chemistry and macroscopic chemical reaction engineering as an essential discipline for the realization of a sustainable society. Research was divided into three areas; the development of reaction fields using structured catalysts, the control of catalytic functions using reaction fields, and the design of catalytic reaction fields for achieving "green" chemical processes. Each of these research fields was further divided into three subgroups. Importantly, each division worked together toward achieving the overall result of catalytic reaction engineering. This project produced many useful and progressive results, as presented at the 10th Asian Pacific Confederation of Chemical Engineering (APCChE 2004).
