1. catalyst that is used to make alkene epoxidation, described catalyst comprises:

  • the silver that deposits on carrier and the carrier, rhenium promoter, first co-accelerator and second co-accelerator;

    The rhenium that wherein deposits on the carrier promotes dosage greater than 1mmol/kg, with respect to the catalyst weight meter;

    First co-accelerator is selected from sulphur, phosphorus, boron and their mixture;

    Second co-accelerator is selected from tungsten, molybdenum, chromium and their mixture;

    WithFirst co-accelerator that deposits on the carrier and the total amount of second co-accelerator are 3.8mmol/kg at the most, with respect to the catalyst weight meter.
