Abstract
This invention relates to a hydrogen spillover-based catalyst and use thereof, wherein a hydrogen activation metal cluster is dispersed in the form of being encapsulated in a crystalline or amorphous aluminosilicate matrix which is partially or fully structurally collapsed zeolite, thereby exhibiting high hydroprocessing or dehydrogenation activity and suppressed C—C hydrogenolysis activity.
Claims8
A hydrogen spillover-based catalyst, comprising:
- crystalline or amorphous aluminosilicate formed by partial or full structural collapse of zeolite having a silica/alumina molar ratio of 2 or less, wherein the zeolite is P-type zeolite, A-type zeolite or X-type zeolite;
- and
- a hydrogen activation metal (M) cluster encapsulated in the aluminosilicate,
- wherein the hydrogen activation metal (M) cluster is incorporated into the zeolite using impregnation or ion-exchange, the metal cluster-incorporating zeolite is ion-exchanged with an ammonium ion (NH4+), and the ion-exchanged zeolite is thermally treated,
- wherein changes in hydrogen and carbon monoxide chemisorption amounts depending on a temperature satisfy the following relation:
- 0.7*(H/M373+H/M473+H/M573)/3>(CO/M373+CO/M473+CO/M573)/3
- wherein H/M is a chemisorption amount (mol) of a hydrogen atom per total mol of M, CO/M is a chemisorption amount (mol) of carbon monoxide per total mol of M, and subscripts represent adsorption temperatures (K).
