TL;DR: In this paper, the extraction of Cretaceous bituminous coal by quinoline, using ultrasonic energy, was investigated, and the results indicated that at least 58% of the organic matter is mobile and can be extracted from this coal without rupturing any chemical bonds.

TL;DR: In this paper, the compositions of acetone, tetrahydrofuran and pyridine extracts from a bituminous coal were studied using mass spectrometry and the main components were identified.

TL;DR: In this article, the formation of pyridine insolubles and the disappearance of liquid anthracene as a function of time over the temperature range 465-525°C were measured.

TL;DR: In this article, several donors with different numbers and reactivities of donorable hydrogens were examined in the hydrogen-transferring liquefaction of an Australian brown coal, and the design of a donor solvent was proposed.
Abstract: Several donors with different numbers and reactivities of donorable hydrogens were examined in the hydrogen-transferring liquefaction of an Australian brown coal. The reactivities of donors, as well as the solvent/coal ratio, are very important for the yields of oil and asphaltene. The design of a donor solvent is proposed

TL;DR: In this paper, the liquefaction kinetics of Powhatan No. 5 mine coal (Pittsburgh Seam) in the presence of SRC-II recycle solvent at short contact times (<10 min) and temperature and pressure ranges of 573-723 K and 10.3-13.8 MPa are examined in a well-mixed reactor.
Abstract: The liquefaction kinetics of Powhatan No. 5 mine coal (Pittsburgh Seam) in the presence of SRC-II recycle solvent at short contact times (<10 min) and temperature and pressure ranges of 573-723 K and 10.3-13.8 MPa is examined in a well-mixed reactor. In the initial stages of liquefaction, while overall coal conversion (tetrahydrofuran solubles) increases with temperature, oil (pentane solubles) is lost with an increase in temperature. An increase in solvent-to-coal ratio results in an increase of conversion. The initial coal particle size distribution, total pressure, and nature of gas phase (nitrogen or hydrogen) have no significant effect on the production of any of the product of liquefaction for contact times up to 10 min. A lumped kinetic model is presented to describe the product distribution.
