This invention discloses a method for microwave-catalyzed dehydrogenation of naphtha to produce aromatics, specifically comprising the following steps: Step 1, oxidizing and etching the surfaces of four different diameter carbon fibers to obtain four modified carbon fibers; Step 2, preparing four platinum-carbon fibers of different diameters based on the four modified carbon fibers obtained in Step 1; Step 3, preparing a gradient-pore structured platinum-carbon fiber paper based on the four different diameter platinum-carbon fibers obtained in Step 2; Step 4, using the gradient-pore structured platinum-carbon fiber paper obtained in Step 3 to catalyze the dehydrogenation of naphtha to obtain aromatics. This invention uses microwave-assisted catalysis to lower the reaction temperature, achieving localized catalytic heating to reduce side reactions, and also achieves high dehydrogenation efficiency.

An experimental apparatus and method for evaluating the dynamic anti-icing performance of superhydrophobic materials are disclosed, relating to the field of superhydrophobic material anti-icing technology. The technical solution includes a test section containing a model. A substrate is connected to the outer surface of the model, and a heating film is placed between the substrate and the model. The beneficial effects of this technical solution are: by adding a heating film under the substrate, the initial freezing time in ultra-low temperature experiments is effectively delayed, ensuring that the test piece does not immediately freeze when the ultra-low temperature is activated, thus guaranteeing the accurate acquisition of the initial freezing time. Simultaneously, by combining a high-speed camera and a thermal imaging camera, the freezing process and degree can be visually observed, providing a visual basis for comprehensive evaluation. When the leading edge of the substrate freezes, the power of the heating film is increased to melt the ice layer, and the overflow water re-condenses into overflow ice away from the heating zone. By measuring the relative position of the overflow ice and the reference chord length, the surface lubrication performance of the material can be further evaluated.
