Abstract
The present invention relates to catalyst composition comprising M1/Ga/zeolite and La/binder, wherein M1/Ga/zeolite is a zeolite comprising 0.01-2 wt-% palladium and/or platinum (M1) with respect to the total M1/Ga/zeolite and 0.2-2 wt-% gallium (Ga) with respect to the total M1/Ga/zeolite; and La/binder is a binder comprising 0.5-2 wt-% lanthanum (La) with respect to the total La/binder. Furthermore, the present invention relates to a method for preparing the catalyst composition of the present invention and a process for producing aromatic hydrocarbons comprising contacting a feedstream comprising lower alkanes with the catalyst composition of the present invention under conditions suitable for alkane aromatization.
Claims15
A catalyst composition comprising M1/Ga/zeolite and La/binder,
- wherein the M1/Ga/zeolite is a zeolite comprising 0.01-2 wt-% palladium and/or platinum (M1) and 0.2-2 wt-% gallium (Ga), with respect to a total weight of the M1/Ga/zeolite;
- and
- wherein the La/binder is a binder comprising 0.5-2 wt-% lanthanum (La), with respect to a total weight of the La/binder.
A method for preparing a catalyst composition, comprising:
- (i) depositing Ga on a zeolite to form a Ga/zeolite;
- (ii) depositing M1 on the Ga/zeolite to form a M1/Ga/zeolite;
- (iii) depositing La on a binder to form a La/binder;
- and
- (iv) combining the M1/Ga/zeolite and the La/binder to form the catalyst composition;
- wherein M1/Ga/zeolite is a zeolite comprising 0.01-2 wt-% palladium and/or platinum (M1) and 0.2-2 wt-% gallium (Ga), with respect to a total weight of the M1/Ga/zeolite;
- and
- wherein the La/binder comprises 0.5-2 wt-% lanthanum (La), with respect to a total weight of the La/binder.
A process for producing a product stream comprising aromatic hydrocarbons, comprising
- contacting a catalyst composition with feedstream comprising lower alkanes to produce the product stream comprising aromatic hydrocarbons;
- wherein the catalyst composition comprises M1/Ga/zeolite and La/binder;
- wherein the M1/Ga/zeolite is a zeolite comprising 0.01-2 wt-% palladium and/or platinum (M1) and 0.2-2 wt-% gallium (Ga), with respect to a total weight of the M1/Ga/zeolite;
- and
- wherein the La/binder is a binder comprising 0.5-2 wt-% lanthanum (La), with respect to a total weight of the La/binder.
