Beschreibung
Zusammenfassung:	The present invention discloses a catalytic dewaxing catalyst and its preparation method. It is characterized by that in the ZSM series molecular sieve the zirconium element is introduced, and the introduction method of zirconium is implemented in the course of catalyst formation by means of high-temp. roasting and activation. Said catalyst possesses higher activity, is specially suitable for catalytic treatment of diesel oil and lubricating oil, and mainly is used for improving low-temp. flow property of raw material (for example pour point and viscosity property) in the presence of hydrogengas.
