摘要： The present disclosure relates to systems and processes for adsorptive gas separations where a first gas mixture including components A and B is to be separated so that a first product of the separation is enriched in component A, while component B is mixed with a third gas component C contained in a displacement purge stream to form a second gas mixture including components B and C, and with provision to prevent cross contamination of component C into the first product containing component A, or of component A into the second gas mixture containing component C. The invention may be applied to hydrogen (component A) enrichment from syngas mixtures, where dilute carbon dioxide (component B) is to be rejected such as directly to the atmosphere, and with preferably nitrogen-enriched air as the displacement purge stream containing residual oxygen (component C).

摘要： Disclosed embodiments provide a system and method for producing hydrocarbons from biomass. Certain embodiments of the method are particularly useful for producing substitute natural gas from forestry residues. Certain disclosed embodiments of the method convert a biomass feedstock into a product hydrocarbon by hydropyrolysis. Catalytic conversion of the resulting pyrolysis gas to the product hydrocarbon and carbon dioxide occurs in the presence of hydrogen and steam over a CO2 sorbent with simultaneous generation of the required hydrogen by reaction with steam. A gas separator purifies product methane, while forcing recycle of internally generated hydrogen to obtain high conversion of the biomass feedstock to the desired hydrocarbon product. While methane is a preferred hydrocarbon product, liquid hydrocarbon products also can be delivered.

摘要： Improved adsorbent sheet based parallel passage adsorbent structures for enhancing the kinetic selectivity of certain kinetic-controlled adsorption processes, such as PSA, TSA and PPSA processes, and combinations thereof, are provided. The enhancements in kinetic selectivity made possible through the implementation of the present inventive improved adsorbent structures may unexpectedly enable significant intensification of selected kinetic adsorption processes relative to attainable performance with conventional adsorbent materials in beaded or extruded form. Such process intensification enabled by the present inventive adsorbent structures may provide for increased adsorption cycle frequencies, and increased gas flow velocities within the adsorbent beds, which may increase the productivity and/or recovery of a kinetic adsorption system incorporating the inventive adsorbent structures.

摘要： A system and method for converting biomass into fluid hydrocarbon products to minimize the use of fossil fuels, provide energy and chemical feedstock security, and sustainable and/or carbon neutral electric power, are disclosed. For example, fast pyrolysis can be performed on biomass to produce pygas and char using a maximum processing temperature of about 650° C. The pygas is provided to an independent reactor without the addition of an oxidizing agent for catalytically converting the pygas to hydrocarbons using a maximum processing temperature of about 650° C. A system comprising fast pyrolysis means producing a pygas and char, independent catalytic conversion means downstream of the fast pyrolysis for converting the pygas to hydrocarbons, and a hydrogen source, external to the system and/or produced by a steam reformer by steam reformation of at least a portion of the hydrocarbons, coupled to catalytic conversion means, also are described.

摘要： Embodiments of a thermochemical method to convert lignocellulosic biomass to a useful fuel are disclosed in a process sequence resulting in low levels of depositable tars in the output gas stream. One disclosed embodiment comprises performing a sequence of steps at elevated pressure and elevated hydrogen partial pressure, including fast (or flash) hydropyrolysis of a lignocellulosic biomass feed followed sequentially with catalytically enhanced reactions for the formation of methane operating at moderate temperatures of from about 400° C. to about 650° C. and under moderately elevated pressure (about 5 atm to about 50 atm). A temperature rise in the catalyst above pyrolysis temperature is achieved without the addition of air or oxygen. Gas residence time at elevated temperature downstream of methane formation zones is extended well beyond the time required for methane formation. This sequence results in low depositable tars in the output gas stream.

摘要： Disclosed embodiments address contaminant management challenges that arise during production of desirably contaminant free product fluid in the operation of PSA equipment, and further address the more serious challenges that arise under intermittent operation of PSA equipment. One disclosed embodiment of a PSA apparatus, intended primarily for normal operating cycle speeds of at least 3 cycles per minute, includes a breather fluidly coupled to a feed end of an adsorber with a contaminant-sensitive adsorbent. The breather can be coupled to the feed end through a shutoff valve closed during production and open during shutdown. Other disclosed embodiments of the PSA apparatus used particular sealing strategies for additional sealing of the apparatus, or at least components thereof, from contaminant ingress.
