Integrated technique to produce sustainable bioethanol from lignocellulosic biomass

Abstract

This study focuses on the utilization of mostly available renewable energy resources, such as lignocellulosic biomass, to generate syngas and bioethanol through a hybrid gasification and syngas fermentation process. The lignocellulosic biomass was characterized using TGA, XRD, FESEM with EDX analysis, and gasifying parameters were optimized using Aspen Plus®. In the first stage of this integrated process, hydrogen-containing syngas was generated, and the final product was bioethanol. The forest waste-based syngas produces higher bioethanol than EFB and coconut shell in the presence of biocatalyst. Therefore, bioethanol will be a sustainable biofuel that will satisfy the world's future energy demands.
