摘要： Proposed is a catalyst for capture and conversion of carbon dioxide capable of removing carbon dioxide and converting carbon dioxide into other useful materials at the same time by capturing and converting carbon dioxide in flue gas generated during fossil fuel combustion into a carbon resource and a catalyst for capture and conversion of carbon dioxide manufactured by the method of the same. The catalyst for capture and conversion of carbon dioxide according to the present disclosure can reduce carbon dioxide by capturing carbon dioxide in flue gas generated during fossil fuel combustion. It is possible to convert the captured carbon dioxide into other useful materials by converting the collected carbon dioxide into sodium carbonate or sodium hydrogen carbonate as carbon resources.

摘要： A method of recovering lithium from a lithium-containing material comprises introducing a lithium-containing material to an electrochemical cell, transporting lithium ions from the lithium-containing material through a cation exchange membrane to a catholyte within a cathode chamber of the electrochemical cell, reacting the lithium ions with bicarbonate ions in the cathode chamber to form lithium carbonate, and removing the lithium carbonate from the catholyte. Related methods of recovering lithium from lithium-containing, materials, and related systems are disclosed.

摘要： Method and apparatus for a low maintenance, high reliability on-site electrolytic generator incorporating automatic cell monitoring for contaminant film buildup, as well as automatically removing or cleaning the contaminant film. This method and apparatus preferably does not require human intervention to clean. For high current density cells, cleaning is preferably performed by reversing the polarity of the electrodes and applying a lower current density to the electrodes, preferably by adjusting the salinity or brine concentration of the electrolyte while keeping the voltage constant. Electrolyte flow preferably comprises water and brine flows which are preferably separately monitored and automatically adjusted. For bipolar cells, flow between modules arranged in parallel is preferably approximately equally distributed between modules and between intermediate electrodes within each module.

摘要： A method and/or electrochemical cell for utilising one or more gas diffusion electrodes (GDEs) in an electrochemical cell, the one or more gas diffusion electrodes have a wetting pressure and/or a bubble point exceeding 0.2 bar. The one or more gas diffusion electrodes can be subjected to a pressure differential between a liquid side and a gas side. A pressure on the liquid side of the GDE over the gas side does not exceed the wetting pressure of the GDE during operation (in cases where a liquid electrolyte side has higher pressure), and/or a pressure on the gas side of the GDE over the liquid side, does not exceeds the bubble point of the GDE (in cases where the gas side has the higher pressure).

摘要： The present disclosure provides a method for preparing an alkali and co-producing gypsum, and belongs to the technical field of chemical production. The method comprises the steps of placing a cation exchange membrane into an electrolytic cell, adding a solution of sodium salt of a weak acid and a compound MH to an anode region as an anode electrocatalyst, adding sodium carbonate or sodium hydroxide to a cathode region, adding a compound M as a cathode electrocatalyst, and applying a DC power supply between a cathode electrode and an anode electrode. The electrolysis oxidizes the MH into the M and releases H+, Na+ in the anolyte penetrates through the cation exchange membrane to reach a cathode region to be combined with OH− in the catholyte to generate NaOH, or further absorbs CO2 and converts into Na2CO3; the anolyte containing a large amount of H+ is generated by the electrolysis for dissolution reaction with limestone, and the H+ is consumed to generate Ca2+, and SO42− and Ca2+ are combined to generate high-purity CaSO4 precipitate. According to the present disclosure, a compound capable of generating PCET reaction is used as an electrocatalyst, while M is its oxidation state and MH is its reduction state, and mirabilite and limestone are used as raw materials to realize the preparation of soda ash, caustic soda and gypsum.
