Embodiment

[0028] Coal samples from Xinyang, Shanxi were taken for the following experiments.

[0029] 1. Elemental analysis of Xinyang coking coal, including C, H, O, N, S.

[0030] 2. Perform FTIR spectral analysis on Xinyang coking coal to characterize the functional groups in the coking coal structure, and perform peak fitting on the spectrum of each functional group to calculate FTIR structural parameters.

[0031] (1) Perform FTIR spectrum detection on Xinyang coal, and mark the main absorption peaks of the FTIR spectrum. See the detection spectrum figure 1 , and sort out the positions of the main absorption peaks and their functional groups, the results are shown in Table 1.

Abstract

The invention provides a construction method of a coking coal sulfur-containing macromolecular structure model. The method comprises the following steps that 1, elemental analysis is conducted on coking coal; 2, FTIR spectral analysis is conducted on the coking coal, functional groups in the coking coal structure are represented, and FTIR structural parameters are calculated; 3, XPS analysis characterization is conducted on the coking coal, and existing forms of major elements in the coking coal are analyzed; 4, fitting analysis is conducted on a coking coal <13>C-NMR spectrum, and structure parameters of the coking coal are obtained; 5, the coking coal sulfur-containing macromolecular structure model is constructed; 6, a model compound matched with sulfur structure morphology in the coking coal is screened on the basis of the coking coal sulfur-containing macromolecular structure model. According to the construction method of the coking coal sulfur-containing macromolecular structure model, the coking coal sulfur-containing macromolecular structure model can be accurately constructed, therefore, a theoretical basis is provided for screening the sulfur-containing model compound, and a theoretical basis is provided for carrying out microwave devulcanization research by replacing coal with the model compound.

Description

technical field [0001] The invention relates to the technical field of coal structure model building methods, in particular to a method for building a coking coal sulfur-containing macromolecular structure model. Background technique [0002] Although humans have used coal on a large scale in an industrial manner for hundreds of years, the chemical structure of coal has not yet been fully understood. The consumption of a large amount of coal has caused serious pollution to the environment, and the emission of sulfur in coal has caused serious damage to human health. The huge harm has been paid more and more attention by people. At present, the understanding of coal structure is still at the stage of qualitative description. The study of the composition and structure of coal is an important scientific basis for understanding coal, and the properties of coal are closely related to its composition and structure. During the change process of coal, the chemical reaction takes p...
