Abstract: A method of forming a hydrocarbon product and a protonation product comprises introducing C2H6 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10?2 S/cm at one or more temperatures within a range of from about 150° C. to about 650° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the protonation product. A C2H6 activation system and an electrochemical cell are also described.

Abstract: The present disclosure provides a carbon-based oxygen-enriched combustion method for recirculation of flue gas from a cement kiln. The combustion method includes recirculating the flue gas generated by the cement kiln to a certain degree to concentrate and enrich carbon dioxide in the flue gas of the cement kiln, mixing the carbon dioxide-rich recirculating flue gas of the cement kiln with the pressurized oxygen to obtain the carbon-based oxygen-enriched products, and mixing the carbon-based oxygen-enriched products with the atmospheric-pressure oxygen to obtain carbon-based air which serves as combustion-supporting gas of the cement kiln.

Abstract: An photocontroller with surge protecting function includes an photocontroller unit, a surge protection unit, and an photocontroller base. On the basis of an existing photocontroller unit and an existing photocontroller base, the surge protection unit is integrated inside the photocontroller unit or the surge protection unit can be connected in a plug-in manner. The surge protection unit is connected in parallel to a power supply phase line terminal and a neutral line terminal of the photocontroller unit. A ground line terminal of the surge protection unit is connected, by means of a ground connector, to the conductive part disposed on the photocontroller base. The conductive piece is grounded. The photocontroller and the surge protection function are combined, which can effectively discharge a surge current, suppress a surge voltage, is easy to mount and replace, and can reduce post-maintenance cost.
