Title
(EN) ADDITIVE COMPOSITION FOR REDUCING COKE AND INCREASING DISTILLATE DURING PYROLYSIS OF A FEEDSTOCK, AND METHOD OF USE THEREOF
(FR) COMPOSITION D'ADDITIF DE RÉDUCTION DE COKE ET D'AUGMENTATION DU DISTILLAT PENDANT LA PYROLYSE D'UNE CHARGE D'ALIMENTATION, ET SON PROCÉDÉ D'UTILISATION
Abstract
(EN) The present invention relates to a coke reducing additive composition capable of simultaneously (a) reducing coke formation and (b) increasing distillate yield during pyrolysis of a feedstock in the presence of a plastic material, wherein the feedstock is a vacuum residue (VR), plastic material is a waste plastic material or an olefin polymer (OP) material, or a mixture thereof, and the coke reducing additive composition comprises a naphthenate, preferably a calcium naphthenate, or sodium naphthenate, or a mixture thereof, and to a method of employing the coke reducing additive composition, and to a method of use of the coke reducing additive composition of the present invention. Particularly, in another embodiment, the present invention relates to a coke reducing additive composition capable of simultaneously (a) reducing formation of coke deposits on walls of the processing unit; and (b) reducing fouling caused due to deposits of coke products on walls of the processing unit during pyrolysis of a feedstock in the presence of a plastic material, wherein the feedstock is a vacuum residue (VR), plastic material is a waste plastic material or an olefin polymer (OP) material, or a mixture thereof, and the coke reducing additive composition comprises a naphthenate, preferably a calcium naphthenate, or sodium naphthenate, or a mixture thereof, and to a method of employing the coke reducing additive composition, and to a method of use of the coke reducing additive composition of the present invention. Particularly, in yet another embodiment, the present invention relates to a method to convert a waste plastic into useful chemical commodity.
(FR) La présente invention concerne une composition d'additif de réduction de coke capable (a) de réduire la formation de coke et (b) d'augmenter le rendement de distillat simultanément pendant la pyrolyse d'une charge d'alimentation en présence d'une matière plastique. La charge d'alimentation est un résidu sous vide (RV), le matériau plastique est un matériau plastique usagé ou un matériau polymère d'oléfine (PO), ou un mélange de ceux-ci, et la composition d'additif de réduction de coke comprend un naphténate, de préférence un naphténate de calcium, ou un naphténate de sodium, ou un mélange de ceux-ci. L'invention concerne également un procédé d'utilisation de la composition d'additif de réduction de coke, et un procédé d'utilisation de la composition d'additif de réduction de coke de la présente invention. En particulier, dans un autre mode de réalisation, la présente invention concerne une composition d'additif de réduction de coke capable (a) de réduire la formation de dépôts de coke sur les parois de l'unité de traitement ; et (b) de réduire l'encrassement causé par les dépôts de produits de coke sur les parois de l'unité de traitement simultanément pendant la pyrolyse d'une charge d'alimentation en présence d'un matériau plastique. La charge d'alimentation est un résidu sous vide (RV), le matériau plastique est un matériau plastique usagé ou un matériau polymère d'oléfine (PO), ou un mélange de ceux-ci, et la composition d'additif de réduction de coke comprend un naphténate, de préférence un naphténate de calcium, ou un naphténate de sodium, ou un mélange de ceux-ci. L'invention concerne un procédé d'utilisation de la composition d'additif de réduction de coke, et un procédé d'utilisation de la composition d'additif de réduction de coke de la présente invention. En particulier, dans encore un autre mode de réalisation, la présente invention concerne un procédé pour convertir un déchet plastique en un produit chimique utile.
