- W149726183 abstract "Publisher Summary This chapter describes the fluid catalytic cracking of coal liquids. It presents a study to analyze the effect of prehydrotreating of coal liquids and the addition of hydrogen-donating solvent on the yield of naphtha and middle fractions and on the behavior of coke formation in the fluid catalytic cracking of coal-derived middle and heavy distillates. Catalytic cracking of aromatic, hydroaromatic, and paraffinic model compounds was also carried out to ascertain the reactivity of coal liquid and the effect of added solvent. From the elemental analyses of hydrotreated oils from middle and heavy distillates, the hydrogen content rose from 10.2 to 11.6 wt% for middle distillate and from 9.9 to 10.7 wt% for heavy distillate, respectively. Removal of hetero atoms, especially the denitrogenation of middle distillate, proceeded more effectively in comparison with that of heavy distillate. Lowest nitrogen content of 300 ppm was observed after the hydrotreatment under higher hydrogen pressure of 150 kg/cm 2 G for middle distillate. There were no significant differences in distillation properties of the hydrotreated oils. The hydrogen content and the H/C atomic ratio of the cracked oil dropped to a level comparable with crude middle and heavy distillates. The chapter also describes the conversion and yields of gas and coke from the catalytic cracking of model compounds related to coal liquids." @default.
