A kinetic-based simulation model of palm kernel shell steam gasification in a circulating fluidized bed using Aspen Plus®: A case study

Challenges and Opportunities of Modeling Biomass Gasification in Aspen Plus: A Review

“…The kinetic approach is mostly selected to model fluidized‐bed gasifiers using RCSTR s , , , , RPLUG , , FBR block or user‐defined blocks in case the users want to create their own process unit. Studies based on the kinetic approach are summarized in Tab.…”

“…Even though each study handles the modeling process from a different technological perspective, the main goal is the development of a realistic process model with high efficiency and product quality. The number of studies dealing with biomass gasification has significantly increased, especially within the last decade , and there are many review studies based on a variety of aspects . However, as compiled in Tab.…”

“…The comparison of the model with lab‐ or real‐scale applications is important due to the constraints and the assumptions made in the simulation model. Commonly, syngas compositions derived from author's own experimental data or from literature are used to verify the modeling results . Moreover, the assessment of the developed model for another biomass type plays an important role to test the limitation of the process.…”

“…Another important issue that plays a significant role not only in the modeling but also in model validation is the tar formation. To simplify the models, in most cases, tar formation is not included at all or considered assuming the formation of an inert compound , , . Due to the advances in Aspen Plus enabling more tailored process modeling, more studies employing the kinetic modeling approach were published recently, which included tar formation by representing it as several model compounds , .…”

Strategies for bioenergy production from agriculture and agrifood processing residues

“…Catalytic steam gasification is a promising technique for hydrogen production. Hussein et al have developed a simulation model for the catalytic steam gasification of palm kernel shells in an atmospheric dual fluidized bed gasifier using an Aspen PlusV R simulator [9]. The catalytic adsorbent-based steam gasification of palm kernel shells is studied in a pilot-scale dual fluidized bed reactor using coal bottom ash as a catalyst for hydrogen and syngas production.…”
