Long-reticulate-distance pillared dioctahedral phyllosilicate 2:1, catalyst and conversion process

摘要

The invention relates to dioctahedral phyllosilicates 2:1 whose basal spacing is at least equal to 2.0x10-9 m and which in the interlayer space comprise pillars based on at least one of the compounds that is selected from the group that is formed by SiO2, Al2O3, TiO2, ZrO2, V2O5, or any combination of the latter. Preferably, they contain fluorine. The invention also relates to a process for their preparation that includes treatment with a surfactant, followed by treatment with a primary or secondary amine and at least one alkoxide of an element that is selected from the group that is formed by the elements Si, Al, Zr, Ti and V. The invention also relates to a catalyst that comprises said phyllosilicate, at least one matrix, and optionally a zeolite Y. The invention also relates to a process for converting hydrocarbons with this catalyst, and in particular a hydrocracking process.
