Abstract

Higher hydrogen content of perhydrous coals exhibits a different composition and physicochemical properties in comparison with normal coals. In the present investigation, a structural study of perhydrous coals and coke was done using FTIR and HPLC data. These coals have high volatile matter with high-calorific values and low-moisture content. The structural study suggests that the major structural units of these coals are simple phenols with para-alkyl substituted derivatives. They have high alkyl substitution groups and low aromatic compounds. The structural studies reveal that these coals contain high amounts of low-molecular weight PAH compounds with 1-2 ring structures. These 1-2 ring structures have high H/C ratios as compared to large ring polyaromatic hydrocarbons (PAHs). It may also be one of the reasons for high H/C ratios in these coals. The alkyl groups contribute significantly to their high volatile matter (VM) contents. The presence of alcoholic groups found in pyrolytic products may also be due to the conversion of catechol-like structures to those of cresols. Coal properties, such as moisture, VM, H/C ratio, and CV, do not correlate with the rank as normally classified. A definite relationship has been found between the characteristics of these coals, char/cokes, and aromatic characters (f a , Har).

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • -NH2 groups are involved in Cr(VI) sorption on RHB, as indicated by FTIR peaks at 705, 775 cm-1 before loading and 738, 834 cm-1 after loading.

    “The peaks of wave numbers at 705, 775 cm À1 of Cr(VI) unloaded and at 738, 834 cm À1 after loading of Cr (VI) on surface of RHB were might be attributed to extending vibrations of -NH 2 groups showing their involvement in Cr(VI) soprtion [65].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
