ORGANIC-INORGANIC HYBRID-SUPPORTED CATALYST AND USE THEREOF IN HYDROREFINING AND HYDROCONVERSION

摘要

The invention concerns a supported sulfide catalyst comprising a porous support composed of an organic-inorganic hybrid material for which the covalent link between the organic and inorganic phases corresponds to the formula M-O-Z-R, wherein M represents at least one constituent metal of the inorganic phase, Z represents at least one heteroelement - either phosphorus or silicon - and R represents an organic fragment, and at least one metal from the VIB group and/or the VB group and/or the VIII group. The invention also relates to the use of this catalyst for hydrorefining and hydroconverting hydrocarbon feeds such as petroleum fractions, coal or biomass fractions, or hydrocarbons produced from natural gas.
