Membrane bioreactors for syngas permeation and fermentation [PDF]
Critical Reviews in Biotechnology, 2021 Syngas fermentation to biofuels and chemicals is an emerging technology in the biobased economy. Mass transfer is usually limiting the syngas fermentation rate, due to the low aqueous solubilities of the gaseous substrates. Membrane bioreactors, as efficient gas-liquid contactors, are a promising configuration for overcoming this gas-to-liquid mass ...

High Pressure Moving Bed Biofilm Reactor for Syngas Fermentation
Chemical Engineering Transactions, 2021 Two well-studied strategies to enhance syngas fermentation are elevated headspace pressure, increasing gas-liquid (GL) mass transfer, and moving bed biofilms (MBB) to overcome kinetic growth limitation. A combination of these two methods has not received

Challenges in Syngas Fermentation for Bioethanol Production: Syngas Composition
Engineering Chemistry, 2023 Energy challenges in developing countries are more significant if they continue to use fossil materials and have an impact on air quality. Lignocellulosic biomass can be an alternative to new renewable sources to replace fossil materials. Indonesia produces various sources of lignocellulosic biomass, which can be used in multiple energy sources such as
