    • A process for reforming with hydrogen, or hydroforming, a naphtha in a cyclic reforming unit which contains a plurality of catalyst-containing on stream reactors in series, and a catalyst-containing swing reactor manifolded therewith which can be periodically placed in series and substituted for an on stream reactor while the latter is removed from series for regeneration and reactivation of the catalyst contained therein. In the process, a reactor which is next scheduled for regeneration and reactivation of its near deactivated catalyst is located immediately downstream next in series with a reactor which contains freshly regenerated, reactivated catalyst at the time the latter is initially put on stream so that sulfur released by the freshly regenerated, reactivated catalyst which occurs a short time after the upstream reactor has been returned to service, is adsorbed by the near deactivated catalyst of the reactor next requiring removal from the series for catalyst regeneration and reactivation. Subsequent to this time, and prior to any desorption and release of major concentrations of sulfur from the deactivated catalyst, the reactor used for scavenging the sulfur is then swung out of series for regeneration and reactivation of the sulfided catalyst, and replaced in the series by the swing reactor.

    • A process for reforming naphtha, with hydrogen, in a cyclic reforming unit which contains a plurality of catalyst-containing on-stream reactors in series, and a catalyst-containing swing reactor manifolded therewith which can be periodically placed in series and substituted for an on-stream reactor while the latter is removed from series for regeneration and reactivation of the catalyst contained therein. In the process, the ability of a catalyst to operate in a hydrogenolysis mode and effect sulfur release can be effectively suppressed after the freshly prepared catalyst has been regenerated, and reactivated several times, generally about five times or more, by the addition thereto of sufficient sulfur to maintain an equilibrium amount of sulfur on the catalyst, preferably a maximum of about 0.01 weight percent sulfur. Preferably, a modified catalyst presulfiding regimen is imposed wherein the amount of sulfur added to a fresh catalyst is progressively, and preferably proportionately reduced from one regeneration, reactivation sequence to the next such that, on and after about the fifth regeneration, and reactivation of the catalyst a maximum of about 0.01 weight percent sulfur is added to the catalyst. In a preferred mode of operation, the catalyst of the lead reactors of the series is not directly sulfided, but indirectly sulfided by sulfur added to, and released by the tail reactor, or reactors. An on-stream water wave displaces sulfur from the sulfided catalyst of the tail reactor, or reactors, as it is returned to service, and a water wave from the catalyst of each reactor redistributes sulfur to undersulfided catalysts of other reactors in the form of hydrogen sulfide released to and carried by the recycle gas.

    • C.sub.2 to C.sub.4 olefins are selectively produced from a gas oil or resid in a two stage process. The gas oil or resid is reacted in a first stage comprised of a fluid catalytic cracking unit wherein it is converted in the presence of conventional large pore zeolitic catalyst to reaction products, including a naphtha boiling range stream. The naphtha boiling range stream is introduced into a second stage comprised of a process unit containing a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures ranging from about 500 to 650.degree. C. and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone.
