摘要

A catalyst nominally containing zeolite, preferably HY zeolite and/or ultrastable HY zeolite, clay, alumina and an acidic silica-alumina co-gel matrix. The zeolite is preferably partially exchanged with high La/Ce ratio solution in a wetting step, and rare earths are precipitated onto the matrix. The catalyst has high metals tolerance and is capable of cracking heavy reduced crude oils, producing higher LCO/slurry oil ratio.
