摘要:
The invention concerns a catalyst containing at least one amorphous oxide matrix, at least one carbide and phosphorous deposited on said catalyst or contained in the matrix, in which the carbide contain at least one group VIB element and, optionally, at least one element from group VIII of the periodic table. The invention also concerns the use of the catalyst for hydrodesulphurisation and hydrogenation of aromatic compounds in gas oils with a low sulphur content.
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.
摘要:
The invention concerns a hydrocracking catalyst comprising at least one amorphous or poorly crystallised matrix of oxide type, at least one element from group VB, preferably niobium, at least one zeolite selected from the group formed by zeolites NU-85, NU-86 and NU-87, and at least one element selected among boron and silicon, optionally P, optionally at least one element selected from the elements from group VIB and group VIII, and/or optionally at least one element from group VIIA. The invention also concerns the use of that catalyst in the hydrocracking of hydrocarbon charges.
