Modeling of Radical Activity During Normal and Branched Alkanes Cracking

Popis výsledku v původním jazyce

Steam-cracking process forms main pathway basic commodities production. Due to the process demands of feedstock and energies, there are still optimization efforts. But options of direct data transfer from lab scale to process scale are limited, therefore mathematical models of steam-cracking are excellent tools for this purpose. Development cracking model must deal with many challenges. This paper is focused to kinetic model development and to a description of chemical reaction called hydrogen abstraction specifically. It basically determines conversion of feedstock under steam-cracking conditions. Exact description of this reaction is problematic, because it extremely increases number of chemical reactions considered in system. In this paper, an alternative description is presented. It is based on replacement of all radicals participating in this reaction by an abstract active radical, and a method for estimation of total activity of radicals is also proposed. Simulation results are compared to experimental ones, and shows excellent match.
