Fisher, A

In a process for the pyrolytic conversion and coking of finely divided solid bituminous material and hydrocarbon oil, the solid material is added to the oil, the mixture is subjected to conversion temperature under substantially non-coking conditions, and the heated products are introduced into a coking zone wherein the residue is coked in a relatively thin layer upon a highly heated surface. The vaporous products from the coking zone are subjected to fractionation, whereby their components boiling above the range of the desired final light distillate product of the process are condensed and separated into selected low-boiling and higher boiling fractions. The fractionated vapors of the desired end-boiling point are then subjected to condensation, collected, and the resulting distillate and gas separated. The selected low-boiling fractions of the condensate resulting from the fractionation of the vaporous products are returned to further conversion with the charging stock mixture, and the higher boiling fractions are returned direct to the coking zone for further treatment.
