Kinetic Model Development for Steam Pyrolysis of Dimethylformamide in a Tubular Reactor

This work presents the development and experimental validation of a mathematical model for the steam pyrolysis process for the thermal degradation of CHON amides. Experimental data on the steam pyrolysis of dimethylformamide (DMF) in a nonisothermal tubular stainless steel reactor for different residence times over the temperature range of 973–1273 K were used to develop a reaction network involving 15 components and 10 reactions to model the process. The General Process Modeling System (gPROMS) was used for kinetic parameter estimation and simulation. The model simulations results were found to agree well with experiments carried out over a wide range of operating conditions.
