Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.

Abstract: Secure shared access to encrypted data in a data store is facilitated by using a data control server (DCS) to maintain a data storage reference table (DSRT) for shared data units present in a shared data pool hosted by least one data storage device, and accessible to a plurality of computing entities. The DSRT specifies for each shared data unit identifier information, location information for accessing the shared data unit in the shared data pool, and a hash value which has been computed for the shared data unit. The DCS selectively facilitates a decryption operation by providing hash values which serves as a basis for deriving a decryption key for decrypting shared data units which have been identified.
