Abstract: The present disclosure provides a process for controlling syngas composition from an internal combustion engine-based syngas generator. While air is typically used as an oxidant, with nitrogen (N2) as a diluent, this results in expensive downstream compression, and low feedstock conversion efficiencies. This disclosure provides CO2 as a diluent to reduce N2 concentration in the syngas. In some embodiments, the CO2 diluent may be from either a biogas processing coupled with methanol, DME, and/or hydrocarbon production; or natural gas processing coupled with Fischer-Tropsch (FT) synthesis and/or other hydrocarbon synthesis.

Abstract: Processes for producing a hydrogen-enriched gas stream are described. A hydrocarbon containing feed is processed in a hydrogen production process unit, and the synthesis gas formed is subjected to a water gas shift reaction. The shifted synthesis gas is sent for processing to recover hydrogen and carbon dioxide. The hydrogen and carbon dioxide recovery processes involve separating a purified hydrogen product stream and a purified carbon dioxide stream from the shifted synthesis stream and recycling synthesis gas to the reforming feed after recovery of CO2 and H2, thereby avoiding carbon slip from the process and lowering the overall carbon intensity.

Abstract: A process is provided for forming a fuel or a fuel intermediate from two fermentations that includes feeding an aqueous solution comprising a fermentation product from a first bioreactor to a second bioreactor and/or a stage upstream of the second bioreactor, which also produces the fermentation product. The aqueous solution may be added at any stage of the second fermentation and/or processing steps upstream from the second bioreactor that would otherwise require the addition of water. Accordingly, the product yield is increased while fresh/treated water usage is decreased.
