Catalyst containing zeolite NU85, NU86 or NU87 and a group VB metal and its application in the hydroconversion of hydrocarbon oils

摘要

the invention relates to a hydrocracking catalyst comprising at least one amorphous or poorly crystallized matrix of oxide type, at least one element of group vb, preferably niobium; and at least one zeolite selected from the group consisting of zeolites, nu 85, 86 and 87, naked, naked, vent at least one element selected from among blocking us from the elements of group vib group and viii.at least one element selected from boron, silicon, phosphorus and / or if at least one element of group viia. the invention also relates to the use of the catalyst in the hydrocracking of hydrocarbon charges.
