USE OF A CATALYST FOR OPENING HYDROCARBON RINGS

摘要

The invention relates to the use of a solid catalyst for opening hydrocarbon rings, which is comprised of: a mesoporous zirconium oxide (ZrO₂) support, optionally doped with silica; tungsten oxide (WO₃) in a quantity such that the mean number of tungsten (W) atoms by nm² of specific area of zirconium oxide (ZrO₂) ranges between 0.1 to 9, and; 0.1 to 5 %, with regard to the total weight of the solid catalyst, iridium. The invention also relates to a method for opening the ring of cyclic hydrocarbon compounds by using a catalytic composition of the aforementioned type.
