Conclusion Based on the lab study and field trials at FCC units A, B and C, proprietary catalyst * formulation can be used as an additive in existing FCC units to maximise product yields and selectivities and increase the RON barrels. In a high olefin FCC unit, the commercial demonstration has proven propylene increases by 0.3 wt%. The demonstration/field trial has shown that catalyst * can be used in conventional VGO FCC, resid FCC, and high olefin FCC as an additive and standalone catalyst. * Hindustan Petroleum High Propylene ([HP]2) catalyst system for maximising propylene yields from HP Green R&D Centre, Hindustan Petroleum Corporation Limited, Bengaluru, India.

0.9231 g/cc feed density, 1.6-2.2 wt% sulphur, and 1.3- 1.6 wt% CCR with 7.3-7.5 wt/wt unit cat/oil. A test run was conducted to see the performance of catalyst * as an additive at 10% concentration. Performance of catalyst * showed a 0.42 wt% increase in LPG, 0.31 wt% increase in propylene, 0.2 unit increase in RON, and 0.25 wt% reduc- tion in bottoms. Demonstration as a standalone catalyst in FCC unit D Commercial demonstration as a catalyst was conducted over four months in one of India’s DCC units. Performance of catalyst * showed a 0.3 wt% increase in propylene (17.7 wt% achieved at 132% of design capacity) and an increase in propylene selectivity in LPG from 42.57% to 44.56%. The hydrogen transfer index for catalyst * was 0.3 compared to

In a high olefin FCC unit, the commercial demonstration of catalyst * has proven propylene increases by 0.3 wt%

the base value of 0.4, indicating the propylene selective- ness of the catalyst. During the trial period, there was no observation of incremental catalyst loss from the FCC units due to the addition of proprietary catalyst * . Hence, meeting catalyst compatibility with the existing base catalyst.
