A delayed coking process for making substantially free-flowing shot coke.
A coker feedstock, such as a vacuum residuum, is treated with an
additive, such as a elemental sulfur, high surface area substantially
metals-free solids, process fines, a mineral acid anhydride and the like.
The treated feedstock is then heated to coking temperatures and passed to
a coker drum for a time sufficient to allow volatiles to evolve and to
produce a substantially free-flowing shot coke.
