Title
(EN) DIRECT CATALYTIC CONVERSION OF ALCOHOLS TO OLEFINS OF HIGHER CARBON NUMBER WITH REDUCED ETHYLENE PRODUCTION
(FR) CONVERSION CATALYTIQUE DIRECTE D'ALCOOLS EN OLÉFINES DE PLUS GRAND NOMBRE DE CARBONE AVEC UNE PRODUCTION RÉDUITE D'ÉTHYLÈNE
Abstract
(EN) A catalyst composition for converting an alcohol to olefins, the catalyst composition comprising the following components: (a) a support (e.g., particles) comprising silicon and oxygen; (b) at least one of copper and silver residing on and/or incorporated into said support; and (c) at least one lanthanide element residing on and/or incorporated into said support. The catalyst may also further include component (d), which is zinc. Also described herein is a method for converting an alcohol to one or more olefinic compounds (an olefin fraction) by contacting the alcohol with a catalyst at a temperature of at least 100°C and up to 500°C to result in direct conversion of the alcohol to an olefin fraction containing one or more olefinic compounds containing at least three carbon atoms; wherein ethylene and propylene are produced in a minor proportion of the olefin fraction, and butenes and higher olefins are produced in major proportion.
(FR) L'invention concerne une composition de catalyseur servant à convertir un alcool en oléfines, la composition de catalyseur comprenant les constituants suivants : (a) un support (par exemple, des particules) comprenant du silicium et de l'oxygène ; (b) au moins un élément entre le cuivre et l'argent se trouvant sur ledit support et/ou étant incorporé dans ce dernier ; et (c) au moins un élément lanthanide se trouvant sur ledit support et/ou étant incorporé dans ce dernier. Le catalyseur peut également en outre comprendre un constituant (d), qui est le zinc. L'invention concerne également un procédé de conversion d'un alcool en un ou plusieurs composés oléfiniques (une fraction d'oléfine) par une mise en contact de l'alcool avec un catalyseur à une température d'au moins 100 °C et jusqu'à 500 °C pour conduire à une conversion directe de l'alcool en une fraction d'oléfine contenant un ou plusieurs composés oléfiniques contenant au moins trois atomes de carbone ; l'éthylène et le propylène étant produits en une proportion mineure de la fraction d'oléfine, et les butènes et les oléfines supérieures étant produits en une proportion majoritaire.
