Electrochemical reactor for upgrading methane and small alkanes to longer alkanes and alkenes
This application relates to new process that utilizes electrodes that incorporate acids that facilitate upgrading of methane and other low molecular weight alkanes to higher order hydrocarbon molecules, such as paraffins, olefins, and aromatics, at temperatures less than 250° C. A primary focus of the invention includes methane conversion to ethylene. The first step of the process includes acid containing electrodes that facilitate the activation of the alkane in the anode layer of the electrochemical reactor. Subsequent steps include the separation of protons from produced longer chain hydrocarbons followed by subsequent electrochemical reduction of the protons to yield hydrogen at the cathode or protons combined with oxygen at the cathode to yield water. The reaction steps in the anode upgrade methane to higher order hydrocarbon products.

METHOD FOR PREPARING FLUORESCENT CARBON QUANTUM DOTS BY USING GAS-LIQUID TWO-PHASE PLASMA
A method for preparing fluorescent carbon quantum dots by using gas-liquid two-phase plasma is provided, which relates to the field of fluorescent carbon quantum technology. On the basis of liquid phase plasma, an inert gas is introduced to generate plasma by a gas-liquid two-phase discharge method. The introduction of inert gas facilitates the formation of discharge channels, reduces the difficulty of product synthesis, improves mass transfer rates of active particles, helps to improve synthesis rates of carbon nano-products, increases discharge contact area and enhances discharge stability. A high reaction efficiency and a short time consumption can be realized. A pulsed power supply is adopted for discharge, which has lower energy consumption compared with the direct current discharge. Moreover, the process is simple, raw materials are easy to obtain, and there is no need for catalysts, strong oxidants or strong corrosives, so the purity of the product maybe higher.
