Title (EN) SELECTIVE HYDROGENATION OF BUTADIENE
(FR) HYDROGENATION SELECTIVE DE BUTADIENE
Abstract: front page image
(EN) A process for the selective hydrogenation of dienes in mixed streams of olefin containing hydrocarbons, such as butadiene in a mixed C4 stream with minimum loss of monoolefins is disclosed wherein the reactor is operated at conditions which induce pulse flow. The pulse flow is induced in a downflow boiling point reactor by vaporization of a portion of the liquid feed at proper conditions.
(FR) L'invention concerne un processus destiné à l'hydrogénation sélective de diènes dans des flux mixtes d'hydrocarbures contenant des oléfines telles que le butadiène dans un flux mixte de C4, avec un minimum de pertes de monooléfines. Dans ce processus, le réacteur fonctionne dans des conditions qui induisent un flux pulsé. Le flux pulsé est induit dans un réacteur de point d'ébullition aval par la vaporisation d'une partie du flux d'entrée liquide dans des conditions appropriées.
