  • Catalytic cracking catalyst compositions having improved bottoms conversion
    Patent number: 8642499
    Abstract: A particulate catalytic cracking catalyst which comprises a zeolite having catalytic cracking ability under catalytic cracking conditions, added silica, precipitated alumina and, optionally clay. The catalytic cracking catalyst has a high matrix surface area and is useful in a catalytic cracking process, in particularly, a fluid catalytic cracking process, to improve bottoms conversion at a constant coke formation.
    Type: Grant

  • PROCESS OF CRACKING BIOFEEDS USING HIGH ZEOLITE TO MATRIX SURFACE AREA CATALYSTS
    Publication number: 20110224471
    Abstract: A process for fluid catalytically cracking a hydrocarbon feedstock containing at least one bio-renewable feed fraction using a rare earth metal oxide-containing, high zeolite-to-matrix surface area ratio catalyst is disclosed. The catalyst comprising a zeolite, preferably a Y-type zeolite, a matrix, at least 1 wt % of a rare earth metal oxide, based on the total weight of the catalyst. The zeolite surface area-to-matrix surface area ratio of the catalyst is at least 2, preferably greater than 2.
