Definitions

  • the present disclosure relates to a fluid catalytic cracking (FCC) catalyst additive composition and its process of preparation.
  • FCC fluid catalytic cracking
  • Fluid Catalytic Cracking is a process which employs specialized catalysts known as FCC catalysts to facilitate the catalytic cracking of heavy hydrocarbon feedstock, such as vacuum gas oil, to lighter products, such as naphtha and other distillate range fractions.
  • One of the significant objectives of carrying out the afore-stated cracking process is to convert the left-over heavy fraction obtained during the derivatization of crude oil into low molecular weight beneficial chemicals such as propylene, light cycle oil, liquefied petroleum gas, gasoline, olefinic gases and the like. After isolation, these products are recycled in the industry; which not only makes the industrial processes economical but also satisfies the ever increasing demand of the afore-stated chemicals.
  • zeolites are used as FCC catalysts.
  • Zeolites that are used in the FCC units are typically crystalline alumino- silicates which have a uniform crystal structure characterized by a large number of regular microlevel cavities interconnected by a large number of smaller channels.
  • These catalysts act as molecular sieves resulting in selective absorption of molecules having sizes below a defined value and rejection of molecules of larger sizes.
  • a sastisfactory yield of the desirable products is not achieved.
  • there is felt need for developing a catalyst system that is capable of achieving optimum benefits of the FCC process.
  • An object of the present disclosure is to provide a fluid catalytic cracking (FCC) catalyst additive composition.
  • Another object of the present disclosure is to provide a FCC catalyst additive composition having a wide spectrum of industrial applicability.
  • Another object of the present disclosure is to provide a process for the preparation of the FCC catalyst additive composition.

  • the present disclosure further provides a process for the preparation of the FCC catalyst additive comprising admixing at least one pre-dried zeolite with at least one promoter precursor and at least one Group V element precursor to obtain a slurry; agitating said slurry for a time period ranging from 2 to 4 hours to form a thick slurry; heating said thick slurry at a temperature ranging from 50 to 100 °C under vacuum to obtain a dried mass; calcining said dried mass at a temperature ranging from 500 °C to 750 °C at a time period ranging from 4 to 6 hours to obtain a calcined mass; grinding said calcined mass to obtain a ground mass and processing said ground mass to obtain the FCC catalyst additive composition.

  • the afore-stated range has been obtained on the basis of optimization data.
  • the Group V elements are included in the composition to boost the catalytic activity.
  • inclusion of the Group V element in the composition in the afore-stated quantity aids in effecting passivation of the highly active acid sites which in turn results in lower crackability, lesser production of dry gas and increase in the liquid yield.
  • the promoter like the Group V element, enhances the catalytic activity and performance of the zeolite.
  • the promoter included in the composition of the present disclosure is at least one element selected from the group consisting of magnesium, calcium, strontium, barium, copper, iron, nickel, zinc, gallium, indium, thallium and the lanthanide series and is included in the composition in an amount ranging from 1 to 3 % of the total weight of the zeolite.
