摘要：A hydrocarbon conversion system wherein a hydrocarbon feed is converted tolower boiling products in a reactor (K) by contact at elevated temperature with fluidizedsolid material, spent material containing coke from said reactor is separated fromreaction products and stripped of volatile hydrocarbons in a stripping zone (D), strippedsolid material is regenerated with oxygen-containing gas in a regeneration zone (B), andhot freshly regenerated fluidized material is returned to the reactor (K), characterised bycarrying out both the conversion and the regeneration in a dilute phase and passing all ofthe solid material from the reactor (K) and the regeneration zone (B) through respectivepreseparators (E) wherein rapid disengagement of solids and gases occur and from whichthe solid material is returned to respective beds in respective vessels (C,D) other thansaid reactor (K) and regenerator (B).
