Potential of Membrane-Based Separation Methods for Producing Low-Carbon Petrochemicals and Renewable Jet Fuels from ABE Fermentation Products (A Review)

This review analyzes existing strategies for intensifying bioalcohol production via acetone–butanol–ethanol (ABE) fermentation focusing on the use of membrane concentration techniques. It also discusses the potential applications of the resulting concentrates as feedstocks for low-carbon fuels and petrochemicals. The review comprises three parts: (1) the current state of ABE fermentation technology, including its fundamental principles as they relate to biomass type; (2) membrane-based separation techniques for concentrating target fermentation products, with a primary focus on pervaporation and promising membrane types and materials; and (3) the downstream processing of ABE concentrates into high-value-added petrochemicals.
