Summary
This bench-unit program simulated the Catlettsburg H-Coal Pilot Plant start-up procedure in Run 6, which used catalytic cracker slurry oil, an aromatic petroleum oil. The program was designed to explore the reasons for Pilot Plant operational difficulties which included reactor product instability, vacuum pumping difficulties and unexpected product yields. Startup oil, hydroclone overflow and withdrawn catalyst were obtained from the Pilot Plant for use in this run with Illinois No. 6 coal. In this run the ratio of startup oil/coal was varied in Periods 1-10, from 2 to 0.2, while the ratio of recycle oil to coal was increased from 0 to 1.8. Recycle oils generated during this run were used as slurry oils in Periods 11 and 12. Initially, the C/sub 4/-975/sup 0/F total distillate yield was 57.4 W %. As the startup oil feed was eliminated later in the run, the C/sub 4/-974/sup 0/F yield fell to 45.4 W %. Ancillary studies were performed on separator bottoms in order to establish their viscosity and settling characteristics as a function of time. Viscosity measurements were also made on bottoms containing 1 to 30 W % 975/sup 0/F/sup -/ distillate. For comparison, viscosities were measured as a function of temperature using PDU Run 5 hydroclone overflow samples which were vacuum distilled to contain < 33 W % 975/sup 0/F distillate. The propensity toward carbon formation was investigated by a series of Ramsbottom carbon residue (RCR) measurements on separator bottoms which covered the range of startup oil/coal ratios from 2 to 0. Finally, microautoclave tests were performed on startup oil and hydroclone overflow oils in order to assess their ability to dissolve coal.
