Beschreibung
Zusammenfassung:	The embodiment of the invention relates to a desulfurization catalyst as well as a preparation method and application thereof. The catalyst comprises at least one VIII group metal, at least two VIB group metals and one IVA group nonmetal. The invention also discloses a preparation method and application of the catalyst. The catalyst is used for hydrodesulfurization of a diesel fraction containing 4, 6-dimethyl dibenzothiophene, has extremely high hydrodesulfurization activity, realizes ultra-deep desulfurization, and reduces the cost of the catalyst by introducing IVA family nonmetal. 本公开的实施例涉及一种脱硫催化剂及其制备方法和应用，该催化剂包括至少一种VIII族金属，至少两种VIB族金属，一种IVA族非金属组成。本发明还公开了上述催化剂的制备方法和应用。本发明用于含有4,6-二甲基二苯并噻吩的柴油馏分的加氢脱硫之中，表现出极高的加氢脱硫活性，实现了超深度脱硫，并且通过引入IVA族非金属，降低了催化剂的成本。
