New ways to improve the coal liquefaction process continue to be sought with the goal being to find the least expensive method to achieve the greatest coal conversion and the best product slate. Low severity is at logical route taken with this goal in mind. Low severity reduces the need for expensive high-pressure valves, pumps and fittings and reduces the problems of construction and handling of severe slurries. However, because of the often diminished conversion of liquefaction reactions at lower temperatures and pressures, methods must be found to increase reactivity of the coal. The basis for this study is the increase of coal liquefaction reactivity through the combination of the use of cyclic olefins with pretreatment to remove cations.
