Abstract
The present invention relates to stevensite or kerolite type trioctahedral phyllosilicates 2:1 containing fluorine, fluorinated in synthesis in an acid medium and modified post-synthesis to bring about Si/Al and/or Mg/Al substitutions which impart acid properties to the solid. These phyllosilicates may be incorporated in the composition of catalysts used to convert hydrocarbons, in particular for hydrocracking.
