Abstract: The present disclosure relates to the field of hydrocarbon raw material conversion, in particular to a method for converting hydrocarbon raw materials and a device thereof. The method comprises the following steps: 1) reacting a gaseous hydrocarbon raw material with a halogen to produce a haloalkane and a hydrogen halide; 2) reacting the haloalkane provided in step 1) with an active metal to produce a first unsaturated hydrocarbon and a first metal halide; and 3) reacting the hydrogen halide provided in step 1) with an active metal to produce a second metal halide and hydrogen. In an electrochemical system of the present disclosure, hydrocarbon raw materials can be converted into high-value products such as hydrogen, ethylene, acetylene, propylene, graphite, etc.

Abstract: A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal reacts with the nitrogen to produce the metal nitride, and the molten salt provides a new reaction interface for the metal nitride to react with the hydrogen to synthesize ammonia, so that ammonia is produced continuously. In addition, the molten salt prevents the liquid alloy from contacting with the oxygen and the water vapor, which prevents the liquid alloy from being oxidized, thus prolonging its service life.
