Abstract
A method of operating a continuous process employing solid catalyst particles by means of charging a feedstock to a reactor and contacting the feedstock with a dense-phase moving bed of catalyst particles at conversion conditions in a reactor. A hydrogen-rich gas containing unsaturated hydrocarbon compounds is recovered from the reactor effluent and at least a portion is contacted with a hydrogenation catalyst to hydrogenate the olefins. The resulting hydrogenated hydrogen-rich gaseous stream is heated and used to supply heat to a vessel containing solid catalyst particles which are preheated and subsequently introduced into the reactor.
