Efficient and cost-effective recovery of product fuels is one of the important steps in a syngas fermentation process. A wide range of techniques have been investigated to recover or separate different products. 

Adsorption has been widely used for the recovery of a wide range of products generated in gas fermentation. The product fuels from syngas fermentation, such as butanol... 

In the past decade, syngas fermentation for the production of value-added fuels and chemicals has been extensively investigated at the laboratory scale. Some pilot- and full-scale processes have also been developed, and a number of commercial or semicommercial facilities are available and listed in Table 12.2 (Innovate Arkansas LanzaTech INEOS COSKATA).
