Mikrokinetisk
Mikrokinetisk modeling, or microkinetic modeling, is a detailed approach to describing chemical reactions on catalytic surfaces by explicitly considering the elementary steps that make up a reaction network. Rather than using broad, aggregated rate laws, mikrokinetisk modeling enumerates individual processes such as adsorption, surface diffusion, surface reactions, and desorption, each with its own rate constant. The method aims to connect molecular-level events with observable macroscopic rates.
A typical mikrokinetisk model specifies a network of species and reactions, including gas-phase and surface-bound intermediates.
Applications span heterogeneous catalysis, such as hydrocarbon reforming, ammonia synthesis, methanol production, and various fuel-cell and
