Advanced coal liquefaction catalyst development. Topical report Ebullated bed testing
(1) Task 8 - Ebullated Bed Testing - was successfully completed during a 23-day run on HRI's bench scale unit 227; unit performance was excellent. (2) The test, identified as run 227-24, demonstrated close-coupled, two-stage (thermal/catalytic) liquefaction of Illinois No. 6 coal in an integrated mode using process conditions that maintained solvent balance and maintained catalyst activity. (3) Lined-out solvent-balanced operation was maintained for 10 days using a first-stage temperature of 820F (residence time 17.5 min), a second-stage temperature of 728F (1.0 lb coal/lb catalyst/hr) and an atmospheric still cut point of 580F. (4) Yields were all maintained at near constant levels during the 10-day period of lined-out operation. On an maf basis, C1-C3 gas yield averaged 9.1%, C4+ distillate yield averaged 57.0%, and 975F+T yield averaged 19.1%. (5) Product quality was constant during the 10-day period of lined-out operation, as indicated by constant nitrogen and sulfur contents in the light reaction products and several virtually identical inspection of the recycle solvent. (6) Catalyst (AMOCAT-1C) activity was maintained during the 10-day period of lined-out operation. (7) AMOCAT-1C catalyst was also found to maintain physical integrity during ebullated-bed use. (8) By empirical linear regression, PFL solvent quality (microreactor test) was found to correlate with PFL H/C ratio and ratio obtained from H NMR. 3 refs., 13 figs., 13 tabs.
