To provide a second-stage hydrocracking catalyst which provides good yields of middle distillate and heavy naphtha and has a desired improved level of activity.SOLUTION: A second-stage hydrocracking catalyst comprises: a) a zeolite beta having an OD acidity of 20 to 400 μmol/g and an average domain size of 800 to 1500 nm2; b) a zeolite USY having an ASDI between 0.05 and 0.12; c) a catalyst support; and d) 0.1 to 10 wt.% of noble metal; where the second-stage hydrocracking catalyst provides a hydrogen consumption less than 350 SCFB across a range of synthetic conversions up to 37 wt.% when used to hydrocrack hydrocarbonaceous feeds having an initial boiling point greater than 380°F (193°C).SELECTED DRAWING: None 【課題】中間留分および重質ナフサの良好な収率を与え、所望の改善されたレベルの活性を備えている第二段階水素化分解触媒を提供する。【解決手段】ａ）２０〜４００μｍｏｌ／ｇのＯＤ酸性度および８００〜１５００ｎｍ２の平均ドメインサイズを有するゼオライトベータと、ｂ）０．０５〜０．１２の間のＡＳＤＩを有するゼオライトＵＳＹと、ｃ）触媒担体と、ｄ）０．１〜１０重量％の貴金属とを含み、３８０°Ｆ（１９３℃）より高い初留点を有する炭化水素系フィードを水素化分解するために使用されるとき、最大３７重量％の合成変換の範囲にわたって、３５０ＳＣＦＢ未満の水素消費量を与える第二段階水素化分解触媒である。【選択図】なし
