“…In particular, the ultra-stable Y zeolite (USY) in its hydrogen form was selected for its high thermal stability to retain the zeolite porous architecture, crucial for the catalytic application. USY zeolite is wellknown from the sixties of the past century and its use is widespread as a catalyst for the cracking reaction of high molecular weight hydrocarbons, residual of the topping operations of oil (Liu et al, 2022). Its synthesis and dealumination procedure has been optimized for a long time, which results in its low cost (Breck and Smith, 1959;Neamt ¸ et al, 2004a).…”
