Abstract
The direct coal liquefaction of Illinois Number Six River King coal using bis(dihydrobis(l-pyrazolyl)borate)nickel (II) as a catalyst in SRC II (a distillate at 240-450°C) was evaluated at times of 15 minutes. Each run was carried out in a 300 ml magnedrive autoclave reactor under an initial hydrogen pressure of 900-1200 psig and/or at 425-475°C. In case of different hydrogen pressures, the tetrahydrofuran (THF) and cyclohexane conversions increased with increased hydrogen pressure. At the two temperatures of 425°C and 475°C the cyclohexane conversion increased with the increased temperature but the THF conversion decreased. The effects of different solvents and heating-rate of short residence times would require for further study.
