Embodiment Construction
[0035] This application provides a method for detecting the hydrogen storage rate of liquid hydrogen storage materials to solve the problem in the prior art that the calculation of the completion rate of the hydrogenation reaction of ethyl carbazole is usually based on the chromatographic peak area corresponding to each reaction product. The ratio is calculated to obtain its mass fraction; however, due to the different correction factors of different substances, the error in the mass fraction obtained by calculating the ratio of the chromatographic peak area of the reaction product is large, and this application introduces a mass correction coefficient, which is calculated by the normalization method The mass fraction of each product of the hydrogenation reaction is obtained, and finally the completion rate of the hydrogenation reaction is obtained, which provides a more accurate data processing method for the calculation of the hydrogenation completion rate of the organic liq...

The method comprises the following steps: step 1, measuring a mass correction coefficient; step 2, analyzing a product obtained after the sample hydrogenation reaction; step 3, correcting the peak area of the reactant; step 4, calculating the hydrogen storage rate of the hydrogen storage material. According to the scheme, the mass correction coefficient is introduced, the mass fraction of the product of the hydrogenation reaction is calculated through a normalization method, the hydrogenation reaction completion rate is finally obtained, and a more accurate data processing method is provided for calculation of the hydrogenation completion rate of the organic liquid hydrogen storage material.
Description
technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a method for detecting the hydrogen storage rate of a liquid hydrogen storage material. Background technique [0002] Liquid hydrogen storage technology is to store and release hydrogen through reversible hydrogenation / dehydrogenation reaction with hydrogen by means of hydrogen storage solvents with unsaturated C-C bonds such as certain alkenes, alkynes or aromatic hydrocarbons. The organic liquid used for the reversible storage of hydrogen using this technology can be called an organic liquid hydrogen storage carrier or an organic liquid hydrogen storage material. The catalytic hydrogenation stage of the organic liquid hydrogen storage material is to use the catalytic hydrogenation device to store hydrogen in the organic liquid hydrogen storage carrier under certain temperature and pressure conditions (<200°C, 2MPa). Taking ethyl carbazole as an example, tetrahydroe...
