Kinetics of hydroprocessing distillate coal liquids
The objective of the present study was to quantify the kinetics of heteroatom removal and aromatic saturation. Distillate coal liquids from the H-Coal and SRC processes were hydroprocessed in fixed bed, continuous flow catalytic reactors. Commercial CoMo and NiMo on alumina catalysts were employed at conditions of 600--800/sup 0/F, 800--2500 psig hydrogen pressure, and 0.3--4.0 LHSV. The liquid products were analyzed for elemental composition and for aromatic carbon content using C/sup 13/--NMR. Heteroatom removal was modeled using a kinetic expression which was second-order in heteroatom concentration, while aromatic saturation was modeled using a reversible first-order rate expression.
