Effects of accumulated solids and solvent initial boiling point on dissolver performance. Final technical report

Technical Report ·
OSTI ID:7090119

Recycling mineral-rich solid residues (filter cake and Kerr-McGee ash concentrate) to the dissolver of an SRC-I coal liquefaction process is beneficial. Recycling increases the combined yield of oils plus asphaltenes, and decreases the preasphaltene yield, without increasing the hydrocarbon gas yield, without increasing the hydrocarbon gas yield. Filter cake catalyzes the preasphaltenes conversion and solvent hydrogenation reactions, indicating that dissolver solids are catalytically active. 12 references, 39 figures, 39 tables.
