Shenfu coal (SFC) oxidation with RuO4 and NaOCl were studied and compared. Most of organic matter in SFC was converted into soluble species with either of the oxidants. Benzene polycarboxylic acids (BPCAs) and alkanoic acids (AAs) are the main products from the reactions. The products from SFC oxidation with RuO4 are rich in longchain AAs, whereas those with NaOCl predominantly consist of ...
Named after the first director of the North Dakota Geological Survey, Leonard, Leonardite is thought to be formed by the oxidation of lignite coal. Our natural, 100percent organic Humate is not derived from lignite, or even more potent forms of coal, like that peddled by many of our competitors.
The H 2 O 2 degradation of humic acids and lignite from Mír mine (South Moravian region, Czech Republic) resulted in oxidation of aromatic structures and cleavage of aromatic units. The hydrophilic fraction largely dominated the oxidation digest in both parental materials. The presence of polycyclic biomarkers αPhyllocladane, DeAlupane confirms the high plant contribution.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Lignite, or brown coal, is the lowestranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which ...
