  • Patent number: 11198090
    Abstract: A method for regenerating an amine-based, acid gas absorbent using a mixed catalyst containing silver oxide and silver carbonate includes the steps of absorbing an acid gas into an acid gas absorbent having an amine group to obtain an acid gas-absorbed absorbent; and regenerating the amine-based, acid gas absorbent by adding a catalyst mixture containing silver oxide and silver carbonate to the acid gas-absorbed absorbent and by removing the acid gas at a temperature ranging from 40° C. to 86° C. When the amine-based acid gas absorbent is an acid gas absorbent solution and when the acid gas that is absorbed into the acid gas absorbent solution is carbon dioxide, the catalyst mixture efficiently promotes decomposition of carbon dioxide-bound carbamate in the acid gas absorbent solution that absorbs the carbon dioxide through a novel catalytic reaction pathway.

  • Publication number: 20210342031
    Abstract: A device and a method for generating floating images are provided. An optical imaging module generates a first floating image. A sensing module sends a detection signal to sense first position information of a tested object at a first time point, and generates a feedback signal according to the first position information when the first position information is within a contour range of the first floating image. A signal processing module is electrically connected to the optical imaging module and the sensing module to receive the feedback signal and generate at least one control command and/or at least one feedback command corresponding to the feedback signal. The at least one control command is transmitted to a controller to perform corresponding control on the controller, and the at least one feedback command is transmitted to the optical imaging module, so that the optical imaging module generates a second floating image different from the first floating image.
