Abstract: A method to condense and recover CO2 from CO2 containing streams. A first step involve providing at more than one heat exchanger, with each heat exchanger having a first flow path for passage of a first fluid and a second flow path for passage of a second fluid. A second step involves passing a stream of very cold natural gas sequentially along the second flow path of each heat exchanger until it is heated for distribution and concurrently passing a CO2 containing stream sequentially along the first flow path of each heat exchanger, allowing the water vapor portion of the CO2 containing stream to condense and precipitate on the condensing heat exchangers. A third step involves passing a water vapor free CO2 containing stream to a cryogenic heat exchanger to condense, precipitate and recover CO2. This processes results in the recovery of CO2 and water vapor from CO2 containing streams using condensing heat exchangers, chiller, compressor, expander and power generator to recover the low value thermal heat available in CO2 containing waste streams.

Abstract: The present invention discloses a method for preparing a catalyst, comprising the following steps: (1) taking a noble metal salt solution A, adding a modified alumina support material, stirring until uniform and standing; (2) drying the material obtained in step (1) in a vacuum, and calcining at 500° C.-600° C. for 1-4 hours to obtain a powder material containing the noble metal; (3) mixing the noble metal powder material, an adhesive and other components to be added, and ball-milling to obtain a uniform slurry; (4) preparing a noble metal solution B and adjusting pH to 0.5-1; and (5) mixing the slurry of the step (3) with the noble metal solution B, coating the mixture on a support, drying, and calcining at 500° C.-600° C. for 1-2 hours to obtain the target product. The method for preparing the catalyst of the present invention is simple, the conditions of the preparation process are easy to control and the preparation method has strong practicality. The prepared catalyst has a good quality, a low ignition temperature and a high catalytic conversion rate for methane at a relatively low temperature.

Abstract: A system for storage and dosing of ammonia, including a solid ammonia storage material capable of binding and releasing ammonia reversibly by adsorption/absorption. The system is able to release ammonia gradually according to a demand that can vary over time with intermediate periods of no ammonia demand. A main storage unit and a start-up storage unit are provided. The storage units hold ammonia storage material. At least one one-way valve is provided via which the one main storage unit is in communication with the start-up storage unit. The one-way valve prevents any back-flow of ammonia from the start-up storage unit to the main storage unit. Heating devices are arranged to heat the main storage unit and the start-up storage unit separately to generate gaseous ammonia by thermal desorption from the solid storage material. A controller controls the heating power of the main storage unit and the start-up storage unit, thereby enabling ammonia release from at least one of the start-up and/or the main storage unit. A dosing valve controls ammonia flow from the storage units according to a demand.
