As shown in Fig. 1, the O/C atomic ratio of low-rank coal is higher than that of high-rank coal because low-rank coal contains larger quantities of oxygen-containing functional groups, such as -COOH and =O. These functional groups react with oxygen at low temperature, and heat is also generated. Low-rank coal is therefore prone to occur

Conversion of low-rank coal in high temperature water can obtain high-quality solid fuel. It is an effective method for upgrading low-rank coals extensively, lignite treated by hydrothermal process contains lower oxygen content due to the decrease of –OCH 3 (methoxyls) and –COOH (carboxyls), these oxygen functional groups can decompose easily even at a …

Low-rank coals are those that have undergone minimal metamorphic variation in the process of coal formation. Compared with the high-rank coals—bituminous and anthracite, they retain more moisture and volatile and contain less fixed carbon [15]. The low-rank coals are often characterized by: High-moisture content (sometimes >50%)

01-01-1991 0183 32 Extending this approach to Yallourn brown coal, water sorption isotherms gave a water monolayer area of 280 m 2 /g while carbon dioxide areas for a suite of Yallourn coals averaged 260m 2 /g Allardice et al, 1978 indicating that in these low rank coals, the surface is essentially completely covered by hydrophilic sit...

Besides the pyrolysis and alcoholysis, the conversion of low-lank coals under hydrothermal conditions (including sub-and supercritical water) for high-quality solid fuel, coal liquefied oil and gaseous fuels has also been widely investigated. In this review, the development of low-rank coal hydrothermal upgrading, the liquid fuel production ...

Clan Allardice History. Variations of the name include Allardyce and Allardes. The name originates from the old barony of Allardice in the parish of Arbuthnott, Kinkardineshire. The recipient of a charter of William the Lion of the lands of Alrethis took his name from the area. It is thought that it gained it's name from the Middle English ...

Adsorption characteristics of CO2–CH4–H2O-coal matrix systems are extremely important for investigating geological CO2-storage and enhanced coalbed methane recovery. To study the adsorption mechanism of CH4 and CO2 under the equilibrium water state, this study conducted high-pressure mercury intrusion porosimetry, low-temperature N2 adsorption, and …

Herein, the pyrolysis characteristics of low-rank coal under a CO-containing atmosphere was studied via thermogravimetry coupled with mass spectrometry and Fourier transform infrared analysis. Further, the pore structure, carbon chemical structure, and combustion reactivity of the prepared coal chars were characterized via N2/CO2 adsorption, …

1. Introduction Low-rank coals such as lignite and sub-bituminous coal are abundant in China, and account for >40% of proven coal reserves. 1 With consumption of high-rank coal, low-rank coals are playing a more important part in energy supplies. "Coal fines" (CFs) refers to coal with a maximum particle size usually less than one-sixteenth inch and rarely above one-eighth inch.
