Abstract
Compositions and methods for preparing a catalyst composition containing mesoporous materials are described herein. In particular, various embodiments described herein relate to the preparation of catalytic compositions containing a mesoporous zeolite and one or more catalytic nanoparticles dispersed therein. In various embodiments described herein, such catalyst compositions can be used in various catalytic conversion processes, such as hydrocracking.
Claims26
A method for modifying a catalyst composition, said method comprising:
- (a) incorporating one or more catalytic nanoparticles into a mesoporous zeolite to thereby form an initial catalytic zeolite, wherein said mesoporous zeolite has a total 20 to 80 Å diameter mesopore volume in the range of 0.05 to 0.70 cc/g;
- and
- (b) heating at least a portion of said initial catalytic zeolite at a temperature of at least 150° C. to thereby form a heat-modified catalytic zeolite, wherein at least 20 weight percent of the total amount of said catalytic nanoparticles associated with said heat-modified catalytic zeolite are located within the mesopores of said heat-modified catalytic zeolite.
A method for making a catalyst composition, said method comprising:
- (a) subjecting a mesoporous zeolite to ion-exchange with one or more ions of a catalyst metal to form an ion-exchanged catalytic zeolite, wherein said ion exchange incorporates at least a portion of said catalyst ions into the mesopores of said mesoporous zeolite, wherein said mesoporous zeolite has a total 20 to 80 Å diameter mesopore volume in the range of 0.05 to 0.70 cc/g;
- and
- (b) contacting said ion-exchanged catalytic zeolite with one or more pH additives to thereby form a catalytic zeolite, wherein at least 20 weight percent of the total amount of said catalyst metal associated with said catalytic zeolite is located within the mesopores of said catalytic zeolite.
A method for modifying a catalyst composition, said method comprising:
- (a) incorporating one or more catalytic nanoparticles into mesopores of a mesoporous zeolite to thereby form an initial catalytic zeolite, wherein said mesoporous zeolite has a total 20 to 80 Å diameter mesopore volume in the range of 0.05 to 0.70 cc/g;
- and
- (b) heating at least a portion of said initial catalytic zeolite at a temperature of at least 150° C. to thereby form a heat-modified catalytic zeolite, wherein at least 75 weight percent of said catalytic nanoparticles originally associated with said initial catalytic zeolite are maintained within the mesopores of said heat-modified catalytic zeolite.
