  • Patent number: 9592491
    Abstract: The present disclosure discloses an ?-alumina carrier, comprising the elements of lanthanum and silicon both dispersed in the interior and on the surface of the carrier. The mass ratio of the element of lanthanum to the element of silicon is in the range from 0.1:1 to 20:1. The inventors of the present disclosure have made extensive researches into the field of the silver catalyst and alumina carrier thereof, and added the elements of lanthanum and silicon (i.e., bulk phase addition) in preparing the alumina carrier used in the silver catalyst. The carrier thus obtained contains the elements of silicon and lanthanum both in the interior and on the surface thereof, and has improved specific surface area and strength. The silver catalyst prepared with the carrier can react in a low reaction temperature (has a high reaction activity) and has a high selectivity in producing ethylene oxide through oxidation of ethylene.
