In POC Run No. 1 HRI`s Catalytic Two-Stage Liquefaction (CTSL) process was evaluated using Illinois No. 6 coal from Crown II Mine in a 3 ton/day process development unit. Solid Separation was accomplished using a vacuum still and subsequently switched to a Kerr McGee residual oil solvent extraction unit (ROSE-SR{sup SM}). Akzo AO-60 1/16{double_prime} extrudate catalyst, a Ni/Mo supported catalyst, was used in both stages. The temperature of the first stage reactor was in the range of 407{degrees} to 414{degrees}C and about 16{degrees} to 27{degrees}C lower than that of the second stage. Throughout most of the 57 days operations, catalysts were added and withdrawn from each reactor to maintain consistent process performance. In this paper the activity of the withdrawn catalysts from both reaction stages at selected operation periods is discussed in respect to the degree of carbon lay down and total contaminations.
