  • Patent number: 12207098
    Abstract: A spectrum resource determining method includes obtaining sharing information. The sharing information indicates that N first cells and one second cell share a first frequency band, a coverage area of each first cell among the N first cells overlaps a coverage area of the second cell, and N is an integer greater than 1. The method also includes determining a spectrum resource of each first cell among the N first cells in the first frequency band and a first spectrum resource of the second cell. The first spectrum resource is located in the first frequency band, and the first spectrum resource does not overlap the spectrum resource of each first cell among the N first cells in the first frequency band.

  • Patent number: 8779014
    Abstract: The present invention provides a slurry catalyst and a method for preparing the same, and belongs to the technical field of preparing catalyst. Particularly, the present invention provides a slurry catalyst directly used in a slurry bed reactor for synthesizing methanol and dimethyl ether and a method for preparing the same, which uses the complete liquid phase preparation from solution to slurry without the conventional slurry-producing process of firstly forming a solid catalyst and dispersing it into an inert medium after crushing and milling. This catalyst mainly comprises Cu, Zn, Al and Zr, wherein atomic ratios of each of components are Cu/Zn/(Al+Zr)=1/0.1-5/0.15-15 and Zr/Al=1:1.0-1:30, and one or two selected from the group consisting of lanthanide metals, Mn, Mo, Si, V, W, Cr, Mg, Ni, K, Pd, Rh, Ru, Re, Pt and Sr is used a promoter.
