Abstract
A solid acid catalyst, and preparation and use thereof are provided. The catalyst contains a metal oxide carrier and at least one modifying metal component. When the catalyst is characterized by solid nuclear magnetic resonance with trimethylphosphine as the probe molecule, it exhibits a spectral peak in the range of −5 to −20 ppm. The catalyst can be used for hydrocracking reaction of non-aromatic hydrocarbons.
Claims18
A solid acid catalyst comprising:
- a) a metal oxide carrier, wherein the metal oxide carrier is preferably selected from the group consisting of Al2O3, TiO2, ZrO2, ZnO, Nb2O5, CuO, CeO2 or a combination thereof;
- b) at least one modifying metal component, wherein the metal in the modifying metal component is selected from the group consisting of metals of Group VB, Group VIB, Group VIII, Group IVA or Group VA, or a combination thereof, preferably selected from the group consisting of V, Cr, Mo, W, Co, Sn, Bi or a combination thereof;
- wherein when the catalyst is characterized by solid state nuclear magnetic resonance with trimethylphosphine as the probe molecule, the catalyst exhibits a spectral peak in the range of −5 to −20 ppm.
