Title (EN) USE OF CATALYTIC DISTILLATION TO PRODUCE CYCLOPENTANE OR CYCLOPENTENE
(FR) UTILISATION D'UNE DISTILLATION CATALYTIQUE POUR PRODUIRE DU CYCLOPENTANE OU DU CYCLOPENTENE
Abstract: front page image
(EN)A process is disclosed for converting dicyclopentadiene to cyclopentane and/or cyclopentene, wherein dicyclopentadiene is fed to a catalytic distillation column, the dicyclopentadiene is cracked to cyclopentadiene in the catalytic distillation column, the cyclopentadiene is hydrogenated to cyclopentane in the catalytic distillation column, and the cyclopentane is recovered from the catalytic distillation column. The dicyclopentadiene is fed into and cracked to cyclopentadiene at the bottom of the catalytic distillation column. Hydrogen is then fed to the catalytic distillation column below the catalytic zone, where cyclopentadiene is hydrogenated as it is produced, thus suppressing polymerization of the cyclopentadiene. The resulting cyclopentane and/or cyclopentene vapor phase stream is condensed, thereby producing a liquid stream of cyclopentane and/or cyclopentene and a vapor stream of hydrogen and other off-gas by-products.
(FR)L'invention concerne un procédé de conversion de dicyclopentadiène en cyclopentane et/ou cyclopentène, consistant à fournir le dicyclopentadiène dans une colonne de distillation catalytique, à craquer dans celle-ci le dicyclopentadiène afin d'obtenir du cyclopentadiène, à hydrogéner dans la colonne de distillation le cyclopentadiène afin d'obtenir du cyclopentane, et à récupérer à partir de celle-ci le cyclopentane. On fournit le dicyclopentadiène au niveau du fond de la colonne de distillation catalytique, et on l'y craque. On fournit ensuite l'hydrogène dans la colonne de distillation catalytique, en dessous de la zone catalytique, à l'endroit où le cyclopentadiène est hydrogéné lors de sa production, ce qui permet de supprimer la polymérisation du cyclopentadiène. Puis on condense le courant résultant de cyclopentane et/ou cyclopentène se trouvant en phase vapeur, de manière à produire un courant liquide de cyclopentane et/ou cyclopentène et un courant de vapeur d'hydrogène et d'autres sous-produits gazeux.
