Process for the regeneration of exhausted catalysts, containing one or more calcium aluminates, for steam cracking reactions, comprising treating said exhausted catalysts in a stream of water vapour at a temperature ranging from 700 to 950&#xb0; C., preferably from 720 to 850&#xb0; C., and at a pressure ranging from 0.5 to 2 atm.

Process for the regeneration of catalysts for steam cracking

Electrolytic membrane for light rechargeable batteries essentially consisting of:

Electrolytic membrane and process for its photo-crosslinking on a

Composite cathode, process for its preparation and its use in solid

A solid polymeric electrolytic membrane comprising a solution of an ion compound in a cross-linked polyether including a liquid plasticizer obtained by: a) copolymerizing a vinyl ether of the formula:

Solid polymeric electrolyte including a cross-linked polyether

The instant invention provides a solid, polymeric electrolyte in membrane form, constituted by a solid solution of an ionic compound in a crosslinked polyether, characterized in that said polymeric electrolyte is obtained by (1) blending a prepolymer, an ionic compound, a plasticizer, and a free-radical-generating activator; and (2) applying the resulting blend on an inert carrier and exposing said blend to a source of ultraviolet light, thermal radiation or electron beam, until the blend is completely crosslinked. The instant invention also provides an electrolyte separator for use in electrochemical devices, optical and electrochemical displays and sensors, which comprises the polymeric electrolyte of the instant invention.
