TL;DR: The authors showed that using lignin to a reaction mixture of coal plus hydrogen-donor solvent promoted more extensive depolymerization of the coal at lower temperatures, and that using guaiacol as solvent further increased coal conversion.

TL;DR: In this paper, the authors observed that catalysis due to sodium lignosulphate leads to a decrease in the values of the kinetic parameters E and A with increase in catalyst concentration, while catalytic due to ferric nitrate shows the reverse trend for the same carbon substrate.

TL;DR: In this article, the pyrolysis and steam gasification of nickel-loaded Yallourn coal were carried out in a fluidized bed reactor at ambient pressure, with the addition of nickel catalyst.

TL;DR: The influence of hydrogen and carrier or diluent gases on water vapor gasification was studied at total pressures between 0.15 and 2 MPa with chars prepared at 600°C from brown coal, sugar, and polyvinyl chloride and with a glassy carbon (HTT 1100°C) as mentioned in this paper.

TL;DR: In this paper, a suite of coals of different ranks covering brown coal to semianthracite were converted to coke by heating between 1010 and 1300°C for 5-19 h. Under these conditions, the cokes do not undergo significant graphitization.
Abstract: Fullerenes were prepared from a suite of coals of different ranks covering brown coal to semianthracite. Each coal was first converted to coke by heating between 1010 and 1300°C for 5-19 h. Under these conditions, the cokes do not undergo significant graphitization. Electrical arcing of the coke in helium produced fullerenes in yields of 2-8.6%, which compare favorably to using graphite as a source carbon under similar conditions
