Abstract: Method for the preparation of a sorbent material and for use of such a material for separating gaseous carbon dioxide from a gas mixture, preferably for direct air capture, using a temperature, vacuum, or temperature/vacuum swing process, comprising primary amine moieties immobilized on a solid support, wherein the primary amine moieties, in the α-carbon position, are substituted by one hydrogen and one non-hydrogen substituent, wherein the sorbent material is in the form of a monolith, a layer, fibres, or particles, wherein the non-hydrogen substituent is selected from the group consisting of alkyl, alkenyl, arylalkyl, and wherein the solid support of the sorbent material is a porous material. Starting from a precursor of said sorbent material comprising one or multiple keto-groups, said one or multiple keto groups are converted into said primary amine moieties through a reductive amination.

Abstract: Processes and systems for upgrading a hydrocarbon. In some embodiments, the process for upgrading a hydrocarbon, can include contacting a gas that can include one or more C1-C4 hydrocarbons and carbonyl sulfide with a sorbent under conditions sufficient to cause at least a portion of the carbonyl sulfide to sorb onto the sorbent to produce a treated gas lean in carbonyl sulfide and a sorbent rich in carbonyl sulfide. The process can also include contacting the sorbent rich in carbonyl sulfide with a regenerating gas that can include molecular hydrogen, one or more C1-C4 hydrocarbons, or a mixture thereof to produce a regenerated sorbent and a desorb effluent that can include a sulfur-based contaminant. The process can also include introducing at least a portion of the desorb effluent into a pyrolysis zone of a steam cracker and recovering a steam cracker effluent from the pyrolysis zone.

Abstract: The present disclosure provides processes and systems for heat integration in ethanol production. In one embodiment, a feed mixture is distilled with one or more distillation units to remove at least a portion of the water, and form a distillation unit bottom stream, a vaporous overhead stream, and a fusel oil stream. Molecular sieve units are regenerated by vacuum or a combination of vacuum and optionally a portion of the product stream to form one or more regenerate streams. A feed tank is configured to receive at least one selected from a condensed portion of the regenerate streams and a portion of a vaporous depressure stream, to form a feed stream. The energy contained in the depressure vapor is recovered by the depressure vapor contacting the feed tank and heating up at least one stream forwarded into the feed tank.
