Hydrocarbon conversion process comprising once-through coking with hydrotreating and fluid catalytic cracking.

摘要

Disclosed is a process for converting heavy hydrocarbonaceous feedstock to more valuable products. The feedstock is introduced into a coking unit (14) containing a coking zone (12) and a scrubbing zone (24). The bottoms fraction (28) from the scrubbing zone is passed through a microfiltration unit (30), thus removing fine coke particles which are recycled (32) to the coking zone (12). The substantially solids-free filtrate (36) is hydrotreated (48), then passed to a catalytic cracking unit (52).
