  • Patent number: 12091320
    Abstract: A process for producing syngas that uses the syngas product from a partial oxidation reactor to provide all necessary heating duties, which eliminates the need for a fired heater. Soot is removed from the syngas using a dry filter to avoid a wet scrubber quenching the syngas stream and wasting the high-quality heat. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

  • Publication number: 20240276885
    Abstract: Disclosed in the present invention is a digital chip-based digital driving method for a piezoelectric ceramic transformer, comprising the following steps: acquiring a rectified output voltage of a piezoelectric ceramic transformer; comparing the acquired output voltage with a preset voltage, and if there is a difference, adjusting the frequency of a driving signal; and adjusting the step-up ratio of the piezoelectric ceramic transformer by means of the frequency of the driving signal, so that the piezoelectric ceramic transformer outputs the preset voltage. In the present invention, the driving frequency can be changed in a digital way, so as to change the step-up ratio of the piezoelectric ceramic transformer, thereby finally stabilizing the output voltage. The piezoelectric ceramic transformer has stable output voltage, strong environmental adaptability and high reliability.

  • Publication number: 20240116756
    Abstract: A method for enriching a synthesis gas in hydrogen is presented. The method includes adding H2O to the synthesis gas to form a synthesis gas stream that includes hydrogen, carbon monoxide, and steam. The synthesis gas stream has a steam to dry gas molar ratio, S/DG; and an oxygen to carbon molar ratio, O/C. The method includes introducing the synthesis gas stream into a water-gas shift reactor and reacting the synthesis gas stream in the water-gas shift reactor in the presence of a non-iron-based catalyst to produce a shifted synthesis gas. The method further includes controlling an outlet temperature of the synthesis gas stream to remain at or below a critical temperature or to drop to or below the critical temperature by adjusting the S/DG ratio to maintain the O/C ratio below a lower O/C limit or above an upper O/C limit.
