This perspective provides the collective opinions of
a dozen chemical
reaction engineers from academia and industry. In this sequel to the
“Vision 2020: Reaction Engineering Roadmap,” published
in 2001, we provide our opinions about the field of reaction engineering
by addressing the current situation, identifying barriers to progress,
and recommending research directions in the context of four industry
sectors (basic chemicals, specialty chemicals, pharmaceuticals, and
polymers) and five technology areas (reactor system selection, design
and scale-up, chemical mechanism development and property estimation,
catalysis, nonstandard reactor types, and electrochemical systems).
Our collective input in this report includes numerous recommendations
regarding research needs in the field of reaction engineering in the
coming decades, including guidance for prioritizing efforts in workforce
development, measurement science, and computational methods. We see
important roles for reaction engineers in the plastics circularity
challenge, decarbonization of processes, electrification of chemical
reactors, conversion of batch processes to continuous processes, and
development of intensified, dynamic reaction processes.
