Abstract:

Exponentially­improved calculation capacities during the last 20 years have provided the reaction engineering field with powerful tools for better integration of complex reaction mechanisms into kinetics and consequent reactor simulation. However, even in relatively simpler reactions, the prevailing mechanisms and their associated elementary reaction steps are rather difficult to define with precision. This work extends the application of previously­proposed methodology, relying on reaction severity factors as part of the development of phenomenological kinetics for such complex reactions. The severity factors proposed here integrate the roles of reaction space velocity (reciprocal of reaction residence time), temperature and catalyst concentration. Fischer­Tropsch synthesis is chosen to extend the concept for 2 reasons: (1) the reaction is well­documented with abundant results published in the open literature, and (2) interest in “green” hydrocarbons and other organic vectors (i.e. “green” ethanol synthesis) is growing as a means of liquid fuel production from renewable resources.
