MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202441020362 A) filed by Hindustan Petroleum Corporation Limited, Bengaluru, Karnataka, on March 19, 2024, for 'an attrition resistant fcc catalyst and a process for preparation thereof.'
Inventor(s) include Basuvaraj, Suresh Kumar; Loganathan, Kumaresan; Kumari, Sanju; Kumar, Pramod; Sundararaman, Sriram; and Maheshwari, Vipul Kumar.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses an attrition resistant fluid catalytic cracking catalyst and a process for preparation thereof. The process for preparation of an attrition resistant fluid catalytic cracking catalyst includes steps of milling of 15% w/w to 30% w/w of clay, 10% w/w to 30% w/w of boehmite alumina, and water to obtain a slurry. Thereafter acidifying the slurry with protic acid to obtain an acidified slurry. Then adding 5% w/w to 20% w/w of nanocrystals of colloidal silica to the acidified slurry to obtain an acidified clay-alumina-silica slurry. Then adding 20% w/w to 40% w/w of a rare-earth modified ultra stable Y zeolite on the acidified clay-alumina-silica slurry to obtain a final slurry. spray-drying the final slurry to obtain spherical particles. Then calcinating the spherical particles to obtain the attrition resistant fluid catalytic cracking catalyst."
