Abstract
• Low Ash Coal ∼ 1 % • Oil agglomeration was unsuccessful to reduce ash < 0.1 % • Digest in decant oil: • (2:1) solvent:coal, 400 °C, 30 min → 80 - 90 % soluble DAF • Coked at 380 °C (2.5 hr) → 500 °C, Calcined to 1300 °C • Total Coke Yield from coal digests ∼ 35 % • Total Coke Yield from neat solvent ∼ 12 % • Low Sulfur • Coke from coal digests ∼ 0.6 % • Low V and Ni • Coke from coal digests ∼ 10 - 30 ppm • High ash metals (over spec) • Si, Fe, Ca, Na • Optical anisotropy: • Coke from coal digest - Bimodal (fine mosaic, some long range) - Ash • except in anthracene oil (all small, native QI) Lower ash coal digests could be a lower-cost additive to traditional anode pet coke constituents to lower the S content.
