Abstract

The invention relates to an acidic silicoaluminate solid that has a microporous zeolitic phase that is characterized by at least one infrared band between 400-1600 cm−1, an organized mesoporosity that is characterized by the presence of at least one X-diffraction line between 20-100 å, a silica/alumina molar ratio of between 5-250 and an acidity that is measured by infrared analysis via an area of the band at about 1545 cm−1 at least equal to 50 g of dry solid. The invention also relates to a process for the preparation of the solid, a substrate that consists of solid and at least one matrix, and a catalyst that comprises said solid. The catalyst can be used for the conversion of hydrocarbons and in particular hydrocracking.
