Abstract
Petroleum reactors are provided which are comprised of one or more serially disposed reaction zones, each zone containing a suitable catalyst, wherein each reaction zone is followed by a non-reaction zone. One or more of said reaction zones contains a vapor by-pass means such that the vapor from one or more upstream non-reaction zones by-passes one or more downstream reaction zones and is introduced into a downstream non-reaction zone.
