1. a kind of selective catalytic cracking catalyst of improvement is it is characterised in that the initial activity of this catalyst is less than 80, certainlyEquilibration time is 0.1 hour~

  • 50 hours, and equilibrium activity is 35~

    60, and this catalyst includes zeolite, inorganic oxide and optionallyClay, each component accounts for total catalyst weight respectively:

    Zeolite 1 weight %~

    50 weight %, inorganic oxide 5 weight %~

    99 weigh %, glueSoil 0 weight %~

    70 weight %, wherein zeolite is selected from mesopore zeolite and/or large pore zeolite.
