Advanced Gasification-Syngas Fermentation Model
Dr. Hasan Atiyeh’s team has developed an Advanced Gasification-Syngas Fermentation Model to examine various operational scenarios for the hybrid conversion process. The research team investigated the effects of critical syngas fermentation parameters such as specific gas uptake rate, ethanol concentration and substrate gas conversion efficiency on reactor volume and energy requirements for the the gasification-syngas fermentation process. Their Aspen Plus model enabled simulation of commercial production of ethanol from gasification of 1200 tons of switchgrass per day. The results showed that about 37 million gallons of anhydrous ethanol can be produced per year from 1200 tons per day switchgrass. The process yielded about 98 gallons ethanol per dry ton of biomass, which is higher than the 70 gallons ethanol per dry ton of biomass typically achieved by the biochemical platform. This work can be a basis of a detailed techno-economic analysis of the proposed technology to help in designing efficient commercial gasification-syngas fermentation biorefineries.
