Abstract

The present invention relates to the technical field of Fischer-Tropsch synthesis, and specifically to a method and device for the continuous operation of a Fischer-Tropsch synthesis catalyst. On the premise of not reducing an activation effect of a Fischer-Tropsch synthesis catalyst, the operation method provided by the present invention changes an intermittent activation operation of the existing catalyst into a continuous operation, which realizes the continuous operation of the activation process and the online replacement process of the Fischer-Tropsch synthesis catalyst. Particularly, combining a solid-solid heat exchange between a fresh catalyst and an activated catalyst, so that an activation reactor keeps the activation process conditions unchanged, saves on the time consumed by the activation reactor in heating and cooling, pressurizing and depressurizing, and gas replacement, etc., and reduces the operation complexity and energy consumption; moreover, a replacement period and the replacement rate of a deactivated catalyst in a Fischer-Tropsch synthesis reactor are reduced, so that the overall performance of the catalyst in the Fischer-Tropsch synthesis reactor is more stable, thereby effectively reducing the equipment investment cost of the activation reactor.

The present invention relates to the technical field of energy storage. Disclosed in the invention are a composite electrode for a flow cell, a flow cell, and a pile. The composite electrode comprises: a distribution layer, used to distribute an electrolyte; a reaction layer used to receive the electrolyte of the distribution layer and provide an electrochemical reaction site for the electrolyte; and a contact layer, used to reduce the contact resistance of the distribution layer so as to reduce the internal resistance of the flow cell. In the present invention, by means of providing a distribution layer, a reaction layer, and a contact layer, an electrochemical reaction site and an electrolyte distribution site of a composite electrode can be effectively separated, the distribution layer being able to greatly reduce dead zones and channeling caused by uneven flow distribution, and the contact layer being able to greatly reduce the internal resistance of a flow cell. Meanwhile, the distribution layer and the reaction layer can be separately and specially designed, thus improving the output power and energy efficiency of a cell or a pile taking the present composite electrode as an anode and/or a cathode.

Abstract

The present invention relates to the field of silicon fertilizers, and disclosed are a liquid silicon-calcium fertilizer, a preparation method therefor, and the use thereof. The method comprises: (1) putting white mud, a calcium source and an alkali liquor into contact with one another, carrying out a first reaction at 90-110ºC, and subjecting the resulting first product to solid-liquid separation to obtain a first solid; (2) slurrying the first solid to obtain an aqueous slurry, adding a mixed acid solution to the aqueous slurry under stirring conditions for a second reaction, and then subjecting the resulting second product to solid-liquid separation to obtain a second liquid; and (3) adjusting the pH of the second liquid with a pH regulator to 5.5-10, so as to obtain the liquid silicon-calcium fertilizer. The liquid silicon-calcium fertilizer provided by the present invention has a low sodium content, and not only has a higher silicon content, but also has a higher stability.

Abstract

The present invention relates to the technical field of energy storage. Disclosed in the invention are a composite electrode for a flow cell, a flow cell, and a pile. The composite electrode comprises: a distribution layer, used for distribution of an electrolyte; and a reaction layer, used to receive the electrolyte of the distribution layer, and provide an electrochemical reaction site for the electrolyte. The present invention, by means of providing a distribution layer and a reaction layer, an electrochemical reaction site and an electrolyte distribution site of a composite electrode can be effectively separated, the distribution layer being able to greatly reduce dead zones and channeling caused by uneven flow distribution. Meanwhile, the distribution layer and the reaction layer can be separately and specially designed (for example, a material having high electrochemical activity being used as the reaction layer, and a material having a fluid flow distribution strengthening property and excellent electrical conductivity being used as the distribution layer), thus improving the output power and energy efficiency of a cell or a pile taking the present composite electrode as an anode and/or a cathode.
