FCC process is the most important catalytic cracking process in the world. The essential component in
the FCC catalyst is the Y (REHY, USY, REY, REUSY) zeolite. Ultrastable Y (USY) is a highly acidic
zeolite (FAU) commonly used in hydrocracking and fluid catalytic cracking (FCC) catalysts. In this work,
the USY zeolite was synthesized from Na-Y zeolite by chemically method and then they were calcined in
the high temperatures to investigate their thermal stabilization. Finally they were characterized by analytical
techniques such as XRD and IR.
