Resin B and C (separated from hexane insoluble-benzene soluble fraction of Akabira SRC) produced isotropic cokes after carbonization. The pretreatment of heteroatom removal followed by hydrogenation (two-staged pretreatment) was more effective in attaining the anisotropic textures of widely develop
Comparison of laboratory-deashed samples of solvent-refined lignite, subbituminous and bituminous coals on the basis of gross combustion analysis, acid and basic titres, molecular weight, nuclear magnetic resonance, ultraviolet and electron spin resonance spectra including various derived parameters
The basic components contained in a coal liquefaction product obtained from the Wilsonville, Alabama coal liquefaction pilot plant were examined by means of capillary-column chromatographic-mass spectroscopy. A total of 62 of the 150 components observed were identified. The most interesting of the n
Upgraded coal-derived liquids obtained from catalytic hydroprocessing of a 30-70(wt%) blend of SRC-1 with SRC-II have been studied by infrared and proton magnetic resonance spectroscopy, and gel permeation chromatography techniques. Compared with the feed blend, the upgraded liquids exhibit a lower
Solvent-refined coal product has been subjected to numerous analytical techniques in an effort to ascertain its chemical nature. Electron spin resonance, 13C and 'H nuclear magnetic resonance, and mass spectroscopy along with elemental and molecular weight analyses have been employed. High-performa
