Abstract
The invention relates to a process for the regeneration of a catalyst of titanium silicalite type used in particular in reactions for the oxidation of saturated hydrocarbons or for the epoxidation of olefins by treatment with a liquid solution containing an oxidizing agent.
Claims14
A method of synthesis of epoxides by reaction between an olefin and hydrogen peroxide, said reaction employing regenerated titanium silicalite catalyst, the catalyst being regenerated by a process which comprises treating a spent titanium silicalite catalyst with a liquid solution comprising at least one oxidizing agent chosen from hydrogen peroxide, ozone and organic peroxide compounds, and maintaining the pH of the solution in the range from 4 to 7.
