Kinetic model and CFD simulation for an entrained flow coal hydrogasifier and influence of structural parameters

A comprehensive three-dimensional numerical model has been developed to for entrained flow coal hydrogasifier reactor. The kinetic model includes water evaporation, Johnson and Tran hydropyrolysis model, semichar reactions and secondary tar hydrocracking reactions. Numerical CFD(Computational Fluid Dynamics) simulation were performed using this model on a 6 t/d hydrogasifier reactor and the predictions are in good agreement with experimental...
