Catalytic hydroprocessing of SRC-II heavy distillate fractions. 3. Hydrodesulfurization of the neutral oils

“…Characterization of the individual hydrodesulfurization reactions occurring during the conversion of whole coal liquids is lacking; the literature emphasizes catalyst screening results (Stiegel et al, 1982) and development of preliminary processing correlations (Stein et al, 1977;Angevine et al, 1979;Sullivan, 1981Sullivan, , 1982Ryan, 1979;Epperly, 1982). This literature provides an indication of the severity of catalytic hydroprocessing required to meet fuel specifications such as smoke point, flash point, stability, density, and cetane or octane numbers; catalyst deactivation data are lacking.…”
