The present invention concerns doped catalysts on a mixed zeolite/alumino-silicate support with a low macropore content, and hydrocracking/hydroconversion and hydrotreatment processes employing them. The catalyst comprises at least one hydrodehydrogenating element selected from the group formed by elements from group VIB and group VIII of the periodic table and a doping element in a controlled quantity selected from phosphorus, boron and silicon, and a support based on zeolite Y defined by a lattice parameter a of the unit cell in the range 24.40&#xd7;10m to 24.15&#xd7;10m and silica-alumina containing a quantity of more than 5% by weight and 95% by weight or less of silica (SiO).

Zeolitic catalyst with a controlled doping element content, and improved process for processing hydrocarbon feeds

An olefin oligomerization process employs a particular silica-alumina catalyst which comprises a non zeolitic support based on silica-alumina containing a quantity of more than 5% by weight and 95% by weight or less of silica (SiO) and has the following characteristics: a mean pore diameter, measured by mercury porosimetry, in the range 20 to 140 &#x212b;; a total pore volume, measured by mercury porosimetry, in the range 0.1 ml/g to 0.6 ml/g; a total pore volume, measured by nitrogen porosimetry, in the range 0.1 ml/g to 0.6 ml/g; a BET specific surface area in the range 100 to 550 m/g; a pore volume, measured by mercury porosimetry, included in pores with a diameter of more than 140 &#x212b;, of less than 0.1 ml/g; a pore volume, measured by mercury porosimetry, included in pores with a diameter of more than 160 &#x212b;, of less than 0.1 ml/g; a pore volume, measured by mercury porosimetry, included in pores with a diameter of more than 200 &#x212b;, of less than 0.1 ml/g; a pore volume, measured by mercury porosimetry, included in pores with a diameter of more than 500 &#x212b;, of less than 0.1 ml/g; and an X ray diffraction diagram containing at least the principal characteristic peaks of at least one of the transition aluminas included in the group composed of alpha, rho, khi, eta, gamma, kappa, theta and delta aluminas.

Process for oligomerizing olefins using a silica-alumina based catalyst

This invention relates to doped catalysts on an aluminosilicate substrate with a low content of macropores and the hydrocracking/hydroconversion and hydrotreatment processes that use them. The catalyst comprises at least one hydro-dehydrogenating element that is selected from the group that is formed by the elements of group VIB and group VIII of the periodic table and a dopant in a controlled quantity that is selected from among phosphorus, boron, and silicon and a non-zeolitic substrate with a silica-alumina base that contains a quantity of more than 15% by weight and of less than or equal to 95% by weight of silica (SiO).

Doped catalyst and improved process for treatment of hydrocarbon feedstocks

This invention relates to silico-aluminum substrates, catalysts, and the hydrocracking and hydrotreatment processes that use them. The catalyst comprises at least one hydro-dehydrogenating element that is selected from the group that is formed by elements of group VIB and group VIII of the periodic table and a non-zeolitic silica-alumina-based substrate that contains an amount of more than 5% by weight and less than or equal to 95% by weight of silica (SiO) and has the following characteristics:
