Title (EN) PROCESSES AND SYSTEMS FOR THE CONVERSION OF ACYCLIC HYDROCARBONS
(FR) PROCÉDÉS ET SYSTÈMES POUR LA CONVERSION D'HYDROCARBURES ACYCLIQUES
Abstract:
(EN) This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C5 hydrocarbons to cyclopentadiene in a reactor system. The process includes contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in at least one reaction zone to convert at least a portion of the acyclic hydrocarbons to a first effluent comprising alkenes, cyclic hydrocarbons and/or aromatics. A co-feed comprising H2, C1-C4 alkanes and/or C1-C4 alkenes may also be provided to the at least one reaction zone.
(FR) La présente invention concerne des procédés et des systèmes pour convertir des hydrocarbures acycliques en alcènes, en hydrocarbures cycliques et/ou en composés aromatiques, par exemple en convertissant des hydrocarbures acycliques C5 en cyclopentadiène dans un système de réacteur. Le procédé comprend la mise en contact d'une charge d'alimentation comprenant des hydrocarbures acycliques avec un matériau catalyseur dans au moins une zone de réaction pour convertir au moins une partie des hydrocarbures acycliques en un premier effluent comprenant des alcènes, des hydrocarbures cycliques et/ou des composés aromatiques. Une charge d'alimentation supplémentaire comprenant H2, des alcanes en C1-C4 et/ou des alcènes en C1-C4 peut également être fournie à au moins une zone de réaction.
