PROCESS FOR PREPARING A MESOPORES-CONTAINING CATALYST, CATALYST THUS OBTAINED AND USE THEREOF IN A HYDROCONVERSION PROCESS.

摘要

The invention relates to a process for preparing a hydroconversation catalyst consisting of a modified zeolite Y, comprising the steps of a treatment of a modified zeolite Y by suspension thereof in a basic pH solution, stopping the previous treatment by neutralization of the modified zeolite Y containing solution with an acid-containing solution; filtering and washing the recovered modified zeolite Y solid, drying and optionally calcining the modified zeolite Y solid, placing the modified zeolite Y solid of step d) in contact, with stirring, in an ion exchange solution and optional steaming and/or calcining the modified zeolite Y type compound for obtaining the catalyst containing a modified zeolite Y.
