摘要:
A process and system for separating CO2 from a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and CO2 with an ionic absorbent under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced CO2 content.
摘要:
An aqueous ionic absorbent solution is disclosed containing (a) about 15 wt. % to about 80 wt. % of one or more diluents, based on the total weight of the aqueous ionic absorbent solution; and (b) an ionic absorbent containing a cation and an anion comprising an amine moiety.

摘要:
Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO2) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing CO2 with an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO2-aqueous ionic absorbent solution stream to desorption conditions to form a CO2-rich stream and an aqueous ionic absorbent solution stream having a reduced CO2 content.

摘要:
Processes for the hydrodechlorination of one or more hydrocarbon products derived from ionic liquid catalyzed hydrocarbon conversion reactions provide a dechlorinated product and an HCl-containing off-gas. The dechlorinated product provides liquid fuel or lubricating base oil, and the HCl may be recovered from the off-gas for recycling to the ionic liquid catalyzed hydrocarbon conversion reaction as a catalyst promoter.
摘要:
We provide a hydrodechlorination and hydrogen chloride recovery process, comprising: a) contacting at least one hydrocarbon product with a hydrodechlorination catalyst in the presence of hydrogen under hydrodechlorination conditions to provide: i) an off-gas comprising an HCl, and ii) a dechlorinated product; b) separating the dechlorinated product from the off-gas; c) contacting the off-gas with an adsorbent under HCl adsorbing conditions such that the HCl is adsorbed by the adsorbent; and d) after step c), recovering the HCl from the adsorbent.
摘要:
A process using supercritical water to upgrade a heavy hydrocarbon feedstock into an upgraded hydrocarbon product or syncrude with highly desirable properties (low sulfur content, low metals content, lower density (higher API), lower viscosity, lower residuum content, etc.) is disclosed. The process does not require external supply of hydrogen nor does it use externally supplied catalysts.
摘要:
A reactor for conducting a process using supercritical water to upgrade a heavy hydrocarbon feedstock into an upgraded hydrocarbon product or syncrude with highly desirable properties (low sulfur content, low metals content, lower density (higher API), lower viscosity, lower residuum content, etc.) is described. The reactor is operable under continuous) semi-continuous or batch mode and is equipped with means to enable momentum, heat and mass transfer in and out of and within the reactor.
