Delayed coking process for producing free-flowing coke using a substantially metals-free additive |
摘要 |
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.
