The present disclosure generally relates to method and apparatus for preventing coke formation in reactor vapor feed nozzle of a fractionator column of a fluid catalytic cracking unit. One or more baffles are positioned within the fractionator column to prevent effluent vapor that is directed by the reactor vapor feed nozzle into the feed zone from flowing back into the reactor vapor feed nozzle. The reactor vapor feed nozzle itself, or an internal nozzle coupled to the reactor vapor feed nozzle, may extend at least partially into the feed zone to similarly act as a baffle.

A process is disclosed for shifting the product of a hydrocracker in a hydrocarbon refinery back and forth from a more naphtha focused product slate to a more diesel focused product slate to take advantage of price and demand shifts between gasoline and diesel by using a naphtha selective catalyst and temporarily passivating the catalyst with a basic material such as ammonia in the hydrocracker. The ammonia passivates the acid catalyst sites on the catalyst and produces more total liquids and more diesel with attractive cold flow and pour point properties for a temporary period. When implemented in a temporary manner and the flow of ammonia is suspended the hydrocracker product slate returns to a more gasoline focused slate.

The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.
