A Semi-Mechanistic Approach to Modeling Lipase-Catalyzed Processes with Multiple Competing Reactions: Demonstration for the Esterification of Trimethylolpropane

Biomass
Kinetic models are important tools for guiding the design and optimization of lipase-catalyzed processes. These processes follow the Ping Pong bi bi mechanism, for which mechanistic kinetic equations can be derived.
