Title (EN) METHOD FOR ISOMERISING DEHYDRATION OF NON-LINEAR PRIMARY MONOALCOHOLS ON AN ALKALI-DOPED ZEOLITIC CATALYST
(FR) PROCÉDÉ DE DÉSHYDRATATION ISOMÉRISANTE DE MONOALCOOLS PRIMAIRES NON LINÉAIRES SUR CATALYSEUR ZÉOLITHIQUE DOPÉ D'ALCALIN
Abstract:
(EN) The invention relates to a method for isomerising dehydration of a feedstock comprising at least one primary monoalcohol of formula R-CH2-OH, R being is a non-linear alkyl radical of general formula CnH2n+1, wherein n is an integer from 3 to 20 (preferably isobutanol) operating in gas phase at a weighted mean temperature of 250°C to 400°C, at a pressure of 0.2 MPa to 1 MPa and with a WHSV of 1 h-1 to 18 h-1, in the presence of a catalyst comprising a substrate comprising at least one zeolite having at least one series of channels, the opening of which is defined by a ring with 8 oxygen atoms (8MR), and said zeolite not having been modified by an alkali solution, the catalyst likewise containing at least one binder and at least one alkali element selected among sodium, lithium, potassium, rubidium and caesium, the total content of alkali elements being from 0.03 wt% to 0.70 wt%.
(FR) L'invention concerne un procédé de déshydratation isomérisante d'une charge comprenant au moins un monoalcool primaire de formule R-CH2-OH, R étant un radical alkyl non linéaire de formule générale CnH2n+1 où n est un entier compris entre 3 et 20 (de préférence l'isobutanol) opérant en phase gaz à une température moyenne pondérée comprise entre 250 et 400 °C, à une pression comprise entre 0,2 MPa et 1 MPa et à une PPH comprise entre 1 et 18 h-1, en présence d'un catalyseur comprenant un support comprenant au moins une zéolithe présentant au moins une série de canaux dont l'ouverture est définie par un anneau à 8 atomes d'oxygène (8MR),et ladite zéolite n'ayant pas été modifiée par une solution alcaline, le catalyseur contenant également au moins un liant et au moins un élément alcalin choisi parmi le sodium, le lithium, le potassium, le rubidium et le césium, la teneur totale en élément alcalin étant comprise entre 0,03 et 0,70% poids.
