Abstract:

This research discusses the biomass gasification process for hydrogen production, integrated with a carbon capture process for product purification. A new simulation model was developed in Aspen Plus, incorporating a gasifier, a water–gas shift (WGS) reactor, and a carbon capture unit. Oil palm empty fruit bunches were selected as the biomass feedstock. The simulation investigated the effects of different gasification agents (O₂, air, and steam) and gasifier operating temperatures on hydrogen yield. It also evaluated the influence of MDEA solvent flow rate on CO₂ capture efficiency. Results showed that using a mixture of O₂ and steam with a ratio of 0.5 at 800 °C produced favorable outcomes, with negligible impurities. The addition of steam in the WGS reactor enhanced hydrogen production, with the highest yield achieved at a steam ratio of 0.6. A 2:1 molar ratio of MDEA to CO₂ resulted in up to 99.9% carbon dioxide removal.
