(65e) Challenges in Multiphase Reaction Engineering

The key challenge for reaction engineering of multiphase systems is in the implementation of science - based scale-up methodology for transfer of molecular discoveries to sustainable,  non-polluting technologies that can meet the future energy, environmental, food and materials needs of the world. Available scientific foundations for the needed multiscale approach to process development are briefly reviewed and progress made in replacing empiricism with science discussed. It is recognized that progress in implementing the desired environmentally benign processes depends, in addition to overcoming the remaining technical challenges, on achieving changes in the socio-economic and political arena. Global regulations and peer pressures may be needed to provide the economic incentives for cleaner and sustainable processes.
