    摘要: A modified vacuum distillation and delayed coking process for making substantially free-flowing coke, preferably free-flowing shot coke. A vacuum resid feedstock is used which contains less than about 10 wt. % material boiling between 900° F. and 1040° F. as determined by HTSD (High-temperature Simulated Distillation). The use of such a high boiling resid favors the formation of shot coke instead of sponge or transition coke. The distillate recycle reduces coker furnace fouling potential of the heavier feedstock.

    摘要: In an embodiment, the invention relates to a method for reducing coke agglomeration in petroleum streams derived from coking processes. In a preferred embodiment, the invention relates to a method for mitigating filter fouling from a coker gas oil wherein an oxygen scavenger is employed to remove molecular oxygen and peroxides.
