Abstract

Biomass gasification is a sustainable thermochemical process to produce syngas, offering a renewable alternative to fossil fuel. To date, many studies have been conducted on biomass gasification, particularly focusing on the reaction models of the process. However, existing models are too complex to be applied to control systems or to optimize the process operating conditions effectively, limiting their practical use for industrial applications. To address this, a simple reaction model for biomass gasification was developed in this research. This study presents a simple kinetic-based biomass gasification model developed in a commercial process simulator, Aspen Plus using Japanese Cypress as feedstock. The process was divided into three main parts, pyrolysis, tar cracking, and char reduction stages. Syngas yield trends on gasification temperature and steam to biomass ratio were studied. At around 900 °C, the proposed gasification system produced the highest CO and lowest CO2 concentrations, indicating it as the optimal gasification temperature. These results show consistent trends with the literature, validating the model’s practical applicability. This study also serves as a foundation for further study in process control and optimization.
