ASPEN plus modelling of air-CO₂ and air-steam-CO₂ gasification of Parthenium hysterophorous for hydrogen and carbon monoxide rich syngas production

Abstract

The simulation modelling of air-CO₂ and air-steam-CO₂ gasification of the aggressive weed, Parthenium hysterophorous is performed using an ASPEN Plus simulator and the outcomes are compared with an existing gasification study taken from the literature. The effect of temperature on the biomass gasification process, and the generation of the gases carbon monoxide (CO), carbon dioxide (CO₂), hydrogen (H₂), and methane (CH₄) are estimated in the temperature range of 300 – 1000 °C. The objectives of this study are to identify the important processes within the operating variables of elemental parameters with the gasifying agents (air-CO₂ and air-steam-CO₂) and to understand how temperature impacts the yield of syngas. Research findings from the gasification of biomass by air-CO₂ and air-steam-CO₂ are also used for comparison. The syngas yield appears to be significantly impacted by temperature variation. Due to the introduction of CO₂, the studies of the gas evolution in this gasification process demonstrate a substantial increase in the output % of H₂ and CO due to the introduction of CO₂.
