    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.

This catalyst contains (1) central core particle or particles made of a heat transfer material (HTM) selected from the group consisting of a metal, a metal oxide, a ceramic, and a mixture thereof; and (2) outer particle layer which surrounds the central core particles and is attached to the surfaces of the central core particles by a binder material layer. The outer particle layer has a support and catalyst particles in a powder form containing metal particles disposed on the support. The catalyst having such a dual particle structure shows excellent heat transfer capability and, thus, exhibits high selectivity to a target hydrocarbon. Therefore, the catalyst of the present invention is useful in a fixed-bed reactor for Fischer-Tropsch synthesis for producing hydrocarbons from synthetic gas.
