Abstract
On 3/5/2022, The United States Patent and Trademark Office (USPTO) has granted Patent No. 011318454B1 for the invention “Method and system for renewing spent fluid catalytic cracking (SFCC) catalysts using acid leaching and acid reflux activities” by Ngo Thuy Phuong, Le Phuc Nguyen, Tran Van Tri, Tran Huu Thinh, Luong Ngoc Thuy (Vietnam Petroleum Institute - VPI).
In this invention description, a method and system for renewing spent fluid catalytic cracking (SFCC) catalysts are disclosed which comprises: treating SFCC catalysts using a static reactor designed to uniformly distribute with an oxalic acid solution and its reflux to obtain leached SFCC catalysts; washing with aqueous solution and filtering to collect cleaned and treated SFCC catalyst; and c) executing the cleaned and treated SFCC catalyst with thermal treatment to obtain renewed FCC catalysts.
According to MSc. Ngo Thuy Phuong, World Intellectual Property Organization (WIPO) decided to support the commercialisation of this invention under the "Enabling Innovation Environment (EIE)" program for the Vietnamese government. This is a long-term project focusing on intellectual property management and technology commercialisation for Vietnam.
