Oxidation of Huolinguole Lignite with NaOCl

Huolinguole lignite (HL) was oxidized with aqueous NaOCl solution under mild conditions. The oxidation products were analyzed by GC/MS. In total 111 products from the HL oxidation were detected, most of which were benzene polycarboxylic acids and short-chain alkanoic acids, while a predominant chlorinated compounds such as trichloromethane, dichloroacetic acid, trichloroacetic acid were also identified.

Separation and analysis of lignite bioconversion

2012-7-1 · The lignite samples were oxidized with nitric acid under moderate conditions and then the oxidized samples were placed on a potato medium with isolated fungus for lignite bioconversion. Lignite, oxidized lignite and residual products after bioconversion of lignite were sequentially extracted with petroleum ether, CS 2, methanol, acetone and tetrahydrofuran (THF), and then each extract was

Low Temperature Oxidation Effects on Lignite

In lignite molecular, side chains of aromatic ring structure unit is firstly oxidized. The bridge button or side chains of coal molecular structure unit are easily oxidized at the same time with the structure of the bridge between units fracturing oxidation. Number of aromatic hydrocarbons remains stable after oxidation.
