Hydrocracking catalyst and use of the same

摘要

A hydrocracking catalyst comprises a support, at least one of VIII Group metal components, and at least one of VIB Group metal components. The support comprises an acidic silica-alumina component and alumina derived from a pseudo-boehmite component, wherein the content of the acidic silica-alumina component is 3-80 wt %, the content of alumina derived from the pseudo-boehmite component is 20-95 wt %, based on the support. The support is obtained by mixing, molding, drying and calcining the acidic silica-alumina component with the pseudo-boehmite component, wherein said pseudo-boehmite component comprises pseudo-boehmite PB1 and pseudo-boehmite PB2, wherein the content of PB1 is 10-90 wt % and the content of PB2 is 0-60 wt % on a dry basis and based on the support.

1. A hydrocracking catalyst, comprising a support and at least one of VIII Group metal components and at least one of VIB Group metal components, wherein said support comprises an acidic silica-alumina component and alumina derived from a pseudo-boehmite component, wherein the content of the acidic silica-alumina component is 3-80 wt %, the content of alumina derived from the pseudo-boehmite component is 20-95 wt %, based on the support, characterized in that said support is obtained by mixing, moulding, drying and calcining the acidic silica-alumina component with the pseudo-boehmite component, wherein said pseudo-boehmite component comprises pseudo-boehmite PB1 and pseudo-boehmite PB2, wherein the content of PB1 is 10-90 wt % and the content of PB2 is 0-60 wt % on a dry basis and based on the support, when characterizing PB1 by X-ray diffraction, κ1 and κ2 of said PB1 are respectively from more than 1 to less than or equal to 3, wherein κ1=h2/h1, κ2=h3/h2, and h1, h2 and h3 are respectively peak height of three diffraction peaks in the X-ray diffraction pattern of PB1 at 2θ angle of 24-30°, 35-41° and 46-52°, when characterizing PB2 by infrared spectrogram, δ value of PB2 is 1.5-4.5, wherein δ=I1/(I2+I3), I1 is the peak height of absorption peak at 3665-3680 cm−1 in the infrared spectrogram of hydroxy group of PB2, I2 is the peak height of absorption peak at 3720-3730 cm−1, and I3 is the peak height of absorption peak at 3760-3780 cm−1.
