Abstract

Sorption enhanced gasification (SEG) is a promising technology for
production of a renewable feedstock gas for biofuel synthesis processes.
The technology has been previously demonstrated at pilot scale. Scaling
of the technology to an industrial size requires knowledge from
governing phenomena. One-dimensional bubbling fluidized bed (BFB)
reactor model was developed and validated against experimental data from
200kWth dual fluidized bed facility. Sub-models for biomass
gasification, reactive bed material and fluidized bed hydrodynamics were
incorporated into the model frame. The model gave satisfactory
predictions for bed material conversion, temperature profiles and gas
composition of the producer gas. The conducted validation improved
understanding of bed material conversion, water–gas shift reaction and
hydrodynamics and their role in SEG reactors. Further refinement and
comprehensive validation of the model with additional data from the
pilot is required. The knowledge from the comprehensive validation can
be utilized in simulation of an industrial size reactor.
