Abstract

Biobutanol (n-butanol) has emerged as a crucial bulk chemical and alternative energy source for biofuels. It can be produced through acetone-butanol-ethanol (ABE) fermentation from biomass. However, the traditional separation process of biobutanol presents economic and energetic challenges due to the low concentration of solvent products. This paper reviews the state-of-the-art in product separation technology. Various strategies for efficient and economical butanol recovery are examined and compared, highlighting their advantages and disadvantages. It is concluded that biobutanol production through online product separation technology holds the greatest potential for extracting butanol from fermentation broth. Additionally, the feasibility of gas stripping integrated with ABE fermentation and other separation technologies in biobutanol production is critically discussed. Finally, a techno-economic analysis of biobutanol production is provided to enhance the commercial viability of advanced techniques.

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
