Abstract

The ¹³C chemical shift ranges are representated graphically for the carbon types and the α -circumstances in hydrocarbons and oxygen-containing compounds. The main purpose of the charts is simple and easy utilization of the correlations between ¹³C shift range and the substructure for the structural analysis of the natural products such as coals, soils, lignins and their reaction products.
The ¹³C NMR spectra were observed for Ishikari peat, the extracted residue, the extracted oil, a lignin and a cellulose. In the solid state, CPMAS and the dipolar -ing spectra were observed, and the chemical structures of Ishikari peat were discussed by using the charts. The most different points in structure of Ishikari peat from woods are the inclusion of the alkyl chain structures.

Abstract

In order to evaluate coal for metallugical coke, thermogravimetric analysis, quantification of gaseous products during pyrolysis, caking and coking properties of different rank of coals including air oxidized were investigated. Following results were obtained.
(1) Degree of oxidation of coals can be detected by monitoring the change of CO, CO₂ and CH₄ in pyrolytic gases.
(2) The higher was the CH₄ concentration in the gases, the higher was the resolidified temperature with Gieseler plastometry become. The developement of the optical anisotropy in coke texture was implicated with CH₄ evolution.
(3) Coals with the large extent of thermal weight loss and the higher ratio of CH₄ in pyrolytic gases showed generally excellent plasticity, although the coal gave cokes with higher porosity.
Coking properties of coals were discussed from the view of the structural aspect. The quantification of thermal weight loss and the concentration of CH₄ in pyrolytic gases were introduced as the criteria of coking characteristics.
