Modeling of industrial-scale sorption enhanced gasification process: One-dimensional simulations for the operation of coupled reactor system

Abstract Sorption enhanced gasification (SEG) is a promising technology for producing gas derived from renewable feedstock to be used in biofuel synthesis processes. As response the growing need fuels, an SEG reactor design was developed industrial-scale dimethyl ether (DME) production. A 100 MW th scale concept wood pellets as created by model-based approach. Thus, 1D modeling tool coupled circulating fluidized beds developed. The model investigate dual bed system’s operation gasifier temperature range of 730–790°C. In this range, optimal producer composition without external hydrogen downstream DME achieved at 730°C: 63 % v o l , d b H 2 11 CO 13 . prediction successfully compared against experimental data and results literature. enables investigation yield with different operating parameters, such part-load operation. This advanced capability can develop new control strategies system impact various parameters on yield.
