摘要： In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

摘要： Methods and systems for the electrochemical up-cycling of polymers. A slurry including a mixture of solid plastics flows through an electrochemical cell, which, through an applied potential, the plastics are converted into pure hydrogen, fuels, gasolines, and oxygen hydrogenated compounds that can be used for the synthesis of advanced materials and/or for easier biochemical/thermal degradation. Such methods and systems enables converting plastic waste to into fuels, chemicals, and high value products.

摘要： Methods and apparatus are disclosed for triggering an exothermic reaction under a high hydrogen loading rate. It is generally understood that a high hydrogen loading ratio is an important factor. The present application teaches that a high hydrogen loading rate, that is, achieving a high hydrogen loading ratio in a short period of time, is another important factor in determining whether excess heat can be observed in an exothermic reaction. The present application discloses methods and apparatus for achieving a high hydrogen loading rate in order to trigger an exothermic reaction.
