FCC catalyst additive and a process for preparation thereof

A process for cracking a hydrocarbon feed using an FCC catalyst additive and an FCC catalyst to produce cracked hydrocarbons with enhanced propylene and LPG yields;

• wherein said FCC catalyst additive comprises at least one zeolite in an amount in the range of 30 to 50 wt %;
• at least one clay in an amount in the range of 10 to 40 wt %;
• at least one binder in an amount in the range of 5 to 20 wt %;
• P2O5 in an amount in the range of 5 to 10 wt %;
• and at least one Group IVB metal compound in an amount in the range of 0.1 to 10 wt %, wherein a source of said Group IVB metal compound is an aqueous titania solution comprising a suspension of TiO2 having the crystal size in the range of 10 nm to 30 nm;
• wherein said hydrocarbon feed comprises C5-C12 naphtha, C4-C6 paraffin, vacuum gas oil, slurry oil, heavy crude, biomass, or waste plastic.
