Embodiment 1

[0032] The preparation method of synthetic hydrogen fuel comprises the following steps:

[0033] (1) Attach 300g of catalyst to the ceramic carrier and place it evenly at the bottom of the reactor; pressurize 30kg of carbon dioxide at 5kg / cm 2 After that, it enters a horizontal reactor with an inner diameter of 152.4cm and a length of 1219.2cm, and the flow rate of carbon dioxide is 2.5m / s; at the same time, 35kg of methane is pressurized at 5kg / cm 2 After entering the horizontal reactor, the flow rate of carbon dioxide is 2.5 m / s; under the action of catalyst, the reaction temperature is 750 °C and the pressure is 5 kg / cm 2 React under the conditions; After the reaction, mixed gas is obtained, and the mixed gas flows out from the reactor after the residence time in the reactor is 5 seconds;

[0034] (2) After the mixed gas and the hydrogen stabilizer are mixed uniformly at a mass ratio of 1000:0.0018, the synthetic hydrogen fuel is obtained.

[0035] The catalyst is obtaine...

Abstract

The invention discloses a synthetic hydrogen fuel and a preparation method thereof. The preparation method of the synthetic hydrogen fuel comprises the following steps: (1) pressurizing carbon dioxide which then enters a reactor and reacts with pressurized methane under the effect of a catalyst, wherein the mass ratio of the carbon dioxide to methane is (1-3):(1-3), the reaction temperature is 640-1,340 DEG C, the reaction pressure is 5-80kg / cm<2>, and a mixed gas is obtained after the reaction; and (2) mixing the mixed gas with a hydrogen stabilizer to obtain the synthetic hydrogen fuel. In the invention, the methane and carbon dioxide are used as main raw materials, and the mixed gas containing hydrogen, carbon monoxide and methane is synthesized through the catalysis of the catalyst; and then, the stabilizer capable of stabilizing hydrogen molecules is added to obtain the synthetic hydrogen fuel which meets the using requirements and can be transported safely for long distance. The fuel gas has the advantages of high combustion value, no toxicity or harm, safety, no pollution and the like.

Description

technical field [0001] The invention relates to the technical field of gas fuels, in particular to a synthetic hydrogen fuel and a preparation method thereof. Background technique [0002] The sustainable development of human society and civilization is facing the threat of energy shortage and environmental degradation. The unrestricted exploitation of fossil energy not only leads to its depletion and rising prices, but also the large amount of carbon dioxide released by burning leads to the aggravation of the greenhouse effect, which in turn leads to extreme Weather phenomenon. [0003] Carbon dioxide is the final product of the oxidation of carbon-based compounds, and it is also one of the important sources of carbon in living organisms. After the industrial revolution, with the massive consumption of fossil energy by human beings, CO in the atmosphere 2 Concentrations are significantly higher than before the Industrial Revolution. As one of the greenhouse gases, CO 2 ...
