Reaction engineering is a term broadly referring to the study, improvement, and eventual modifications applied to complex reacting systems. Often our objective is to identify the rate-limiting step or reduce the number of undesirable products or selectively enhance the production rate of certain species. Frequently, this can only be accomplished by detailed knowledge of the reaction mechanism. However, this is often a complicated task for interphase reactions owing to both measurement limitations and slow heat and mass transfer rates that obscure the true chemical rates. In a project involving oceanographers, microbiologists, and chemical engineers, we are measuring and mathematically modeling rates of polynuclear aromatic compound degradation by microbes in marine sediment bioremediation.
