  • Catalyst compositions for improved fluid catalytic cracking (FCC) processes targeting propylene production
    Patent number: 8137534
    Abstract: Catalyst compositions comprising a siliceous zeolite component, either in separately formed catalyst particles or dispersed in the same binder or matrix as other zeolites of the compositions, are described. The catalyst compositions, for example as blends of three different bound zeolite catalysts, are particularly useful in fluid catalytic cracking (FCC) processes due to the reductions in coke and dry gas yields that allow FCC throughput, which is normally constrained by gas handling and/or catalyst regeneration capacity, to be increased.
