MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090399 A) filed by Conser Spa on July 24, 2026, for Process And Apparatus For Continuous Epoxidation In Liquid Phase Of Propene.
Inventors include Iosco, Antonio; Forlin, Anna; and Sneider, Yuri Gabriel.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An improved process and its relating plant for the production of propene oxide in a reaction system in which a heterogeneous catalyst is equally distributed in two twin reactors, operationally interchangeable, which process includes the following phases : (a) start the epoxidation reaction by bringing propene into contact with hydrogen peroxide and a reaction solvent in a first reactor, in a liquid phase using a heterogeneous catalyst at constant temperature and pressure, appropriately selected to obtain at least a minimum yield desired propene oxide in the presence of ammonia; (b ) apply a continuous wash using the feed flow of the reaction solvent to regenerate the catalytic bed of the second reactor, twin of the first, at mild temperature conditions, close to the reaction temperature, in the presence of ammonia; ( c) feeding the stream of the reaction solvent and ammonia coming from the washing of the second twin reactor, which is in the regeneration phase, to the first reactor in which the reaction is taking place and is in productive operation; (d) switch the regeneration operation and the reaction operation between the first and second reactors when the reaction yield falls below a target range.
