Catalyst comprising a NU-88 zeolite, a group VB element and its use for hydroconverting hydrocarbon-containing petroleum feeds

摘要

The invention provides a hydrocracking catalyst comprising at least one NU-88 zeolite, at least one group VB metal, preferably niobium, at least one amorphous or low crystallinity matrix, optionally at least one metal selected from the group formed by group VIB and VIII metals, optionally at least one element selected from the group formed by phosphorous, boron and silicon, and optionally at least one group VIIA element. The invention also relates to the use of the catalyst for hydrocracking hydrocarbon-containing feeds.
