“…Consequently, this approach can be considered as more realistic concerning the real situation in the gasifier, in particular for lower gasification temperatures and shorter residence times. The common gasification reactions used in kinetic modeling are described elsewhere , , , . Aspen Plus allows the integration of the reaction kinetics by a user‐defined Fortran subroutine.…”

“…Even though equilibrium models are less advanced than kinetic models, they are still capable of modeling gasification processes especially for fixed‐bed gasifiers (downdraft or updraft) operating nearly at equilibrium conditions. Still, there are also studies based on this approach to model other types of gasifiers like fluidized‐bed gasifiers , , , , , , , . However, neglecting tar modeling, duration and heterogeneity of the reaction within the gasifier and heat losses limit the modeling to fluidized‐bed gasifiers .…”

Aspen Plus has become one of the most common process simulation tools for both academia and industrial applications. In the last decade, the number of the papers on Aspen Plus modeling of biomass gasification has significantly increased. This review focuses on recent developments and studies on modeling biomass gasification in Aspen Plus including key aspects such as tar formation and model validation. Accordingly, challenges in modeling due to specific assumptions and limitations will be highlighted to provide a useful basis for researchers and end‐users for further process modeling of biomass gasification in Aspen Plus.

“…Although coal gasification is a well established technology, recently the focus has been shifted to biomass gasification to estimate efficiency and performance of the process [5]. Biomass is a favorable alternative to fossiel fuels as it has comparatively lower negative impact on environment, low nitrogen and sulphur content leading to lower NOx and SO 2 emissions.…”

Cogasification of coal and biomass is a new area of research. Cogasification offers several advantages than individual feed gasification. A thermodynamic analysis of lignite coal and rice husk cogasification using only steam was studied by using HSC chemistry software in this paper involving the effect of temperature 500-1200°C and GaCR ratio(1-3) on the product gas composition. The study also focused on calculation of thermoneutral conditions and hundred percent carbon conversion temperature in cogasification of lignite coal and rice husk. Experimental study of co gasification of rice husk and coal was also done at fixed steam to carbon ratio. The experimental study was found to be more kinetically controlled.

Summary A comprehensive model is developed to predict and optimize the hydrogen production via integrated configuration of steam gasification process of biomass and water‐gas shift reaction by taking advantage of the ASPEN plus software and sensitivity analysis techniques. The steam gasification process of three different generations of biomass, including corn cob as the first generation, wood residue and rice husk as second generation, and Spirulina algae as the third, are investigated and evaluated to achieve maximum hydrogen production. This model is successfully validated with experimental data reported in the literature about steam gasification of rice husk in the fluidized bed reactor. The impact of main operating parameters is considered in terms of products composition, hydrogen yield, CO conversion, H2/CO ratio in the gas products stream, and cold gas efficiency (CGE). The results indicated that the maximum hydrogen concentration is achieved at the highest steam to biomass (S/B) ratio in the gasifier and water‐gas shift (WGS) reactor and at the lowest WGS reaction temperature, whereas there is an optimum value about the gasification temperature. The highest CO conversion and H2/CO molar ratio belong to rice husk biomass at all considered range of temperature, whereas they are almost the same for wood residue and Spirulina. The predicted results confirmed that CGE of all feedstocks improves with increasing gasification temperatures and S/B ratio. The steam gasification performance of different feedstocks at 750°C is ranked as wood residue (83.56%) > spirulina (83.47%) > corn cob (74.94%) > rice husk (69.86%). The presented configuration can be applied as a novel approach for process evaluation and optimization through the downdraft biomass gasification integrated with water‐gas shift reaction to intensify the hydrogen production.
