Abstract
A carrier that may be used in the manufacture of an olefin epoxidation catalyst is provided that is prepared from a process involving depositing boron on the carrier and subsequently calcining the carrier. Also provided is an olefin epoxidation catalyst comprising a silver component deposited on such a calcined carrier. Also provided is a process for the epoxidation of an olefin employing such a catalyst and a process for producing a 1,2-diol, a 1,2-diol ether, or an alkanolamine employing the olefin oxide.
Claims31
A process for the preparation of a catalyst comprising:
- depositing boron on a carrier in a quantity of at least 200 ppmw, based on the weight of the carrier;
- subsequently calcining the carrier;
- and
- depositing silver and a high-selectivity dopant on the calcined carrier.
A process for the preparation of a catalyst comprising:
- depositing boron on a carrier in a quantity of at least 1000 ppmw, based on the weight of the carrier;
- subsequently calcining the carrier;
- and
- depositing silver on the calcined carrier.
A process for the preparation of a carrier comprising:
- depositing boron on a carrier in a quantity of at least 200 ppmw, based on the weight of the carrier;
- and
- subsequently calcining the carrier.
