TL;DR: In this paper, the effects of liquid water treatment on Wyodak coal were studied in the presence of n-undecane replacing water in batch reactors with quartz liners for periods of 30 min or 5 h with added N2 (500 psi cold).

TL;DR: In this paper, the effects of pyrolysis conditions on char reactivity were investigated using the Bhatia-Perlmutter model to obtain gasification rate parameters.

TL;DR: In this article, it was shown that the low molecular weight olefins (ethylene, propylene and butadiene) derived from the same precursors in coal, whereas methane, benzene and other pyrolysis products are mainly formed from different components in coal.

TL;DR: In this paper, the effects of solvent swelling and catalyst impregnation on liquefaction conversion behavior in temperature-staged reactions for 30 min each at 215 and 425 °C in H 2 and 95:5 H 2 :H 2 S atmospheres were examined.
Abstract: Two coals, a Texas subbituminous C and a Utah high-volatile A bituminous, were used to examine the effects of solvent swelling and catalyst impregnation on liquefaction conversion behavior in temperature-staged reactions for 30 min each at 215 and 425 °C in H 2 and 95:5 H 2 :H 2 S atmospheres. Methanol, pyridine, tetrahydrofuran, and tetrabutylammonium hydroxide were used as swelling agents. Molybdenum-based catalyst precursors were ammonium tetrathiomolybdate, molybdenum trisulfide, molybdenum hexacarbonyl, and bis(tricarbonylcyclopentadienylmolybdenum). Ferrous sulfate and bi(dicarbonylcyclopentadienyliron) served as iron-based catalyst precursors

TL;DR: In this paper, gasification reactivities of raw and acid-washed coal chars obtained from the three most important coal-bearing regions in Chile have been determined in 0.1 MPa of oxygen using a thermobalance.
