The primary accomplishment of this quarter was the successful completion of Runs 008, 009, and 010. Summary data for these runs is shown in Table I. Run 008 extended for 130 hours on solvent/Dox oil, 15 hours on stored extract, and 6 hours on fresh extract (integrated operation). Run 009 involved Section 600 only, and ran from May 24 through June 1, with the section operating for 67 hours on solvent/Dox oil. Run 010 began on June 21, and for a 109-hour period, Section 600 - Hydrogeneration - was in stable operation on a recycle extract feed stock. The section was brought to stable operation on a 50% Dox oil--50% topped solvent feed. The D-A601D reactor had a catalyst charge, while the DA601A was used as a feed preheater and stabilizer for the feed stock. The concentration of extract in the feed was increased from 21% to 45% while reaction temperatures increased by 35/sup 0/F, from 745 to 780/sup 0/F. Desulfurization as high as 80% was experienced. Disappearance of extract (defined as process material boiling at 825/sup 0/F or higher) was about 27%. Over 7,000 gallons of heavy fuel oil was produced with average sulfur and ash contents of 0.3 and 0.13%, respectively. Run 010, which was terminated to permit work on an external natural gas supply line, demonstrated that stable operation can be achieved and maintained for a prolonged period. In addition, processing conditions have been established which provide a firm basis for setting conditions for future runs. The major problem during Run 010 continued to be the reliability of control instruments monitoring Unit 600 liquid streams.
