Abstract: A total recycle process of the carbonaceous components in the coal gas based on the integration of the CO2 absorption and the electrocatalysis is provided. The disclosure captures CO2 from coal gas using a solution with a primary amine and/or a secondary amine, performs electrocatalytic reduction on the absorption solution to prepare carbon monoxide/hydrogen (CO/H2) reducing gas, and regenerates the absorption solution during the electrocatalytic reduction process. An improved electrolysis process is used to accelerate the production of CO/H2 reducing gas, which is mixed with decarbonized coal gas and returned to the smelting process for recycling.

Abstract: A vehicle charging system enables accurate matching between a vehicle and a charging gun. When a vehicle unlocks its charging port, it sends its parking space identifier to a vehicle server, and upon detecting gun insertion, it also sends a first timestamp. The charging pile server reports the charging gun identifier and a second timestamp when a gun is inserted. The vehicle server cross-references the parking space with pre-stored mappings of candidate guns and compares the first and second timestamps. If exactly one gun matches within a set time threshold, the server issues a charging command to the charging pile server. The pile server then sends a charging instruction to the identified gun, which in turn initiates charging for the connected vehicle.

Abstract: A digital-to-analog converter includes a sampling resistor network circuit, an operational amplifier, a feedback resistor, and a compensation current generation circuit. The sampling resistor network circuit controls a sampling resistance value of the sampling resistor network circuit based on a sampling codeword, and generates an output current based on a voltage difference between a first reference voltage and a voltage at a first input terminal of the operational amplifier as well as the sampling resistance value. The compensation current generation circuit generates a compensation current based on the sampling codeword. The compensation current is used to compensate for an offset current generated by an offset voltage in the sampling resistor network circuit in order to make a sum of the compensation current and the offset current equal to a first constant. The first constant is independent of the sampling codeword.
