  • Radiotherapy device and microwave source thereof
    Patent number: 11984292
    Abstract: The present disclosure is related to a microwave source. The microwave source may include a cathode heater and a thermionic emitter. The cathode heater may include a first component, and a second component enclosing at least a portion of the first component. The thermionic emitter may be configured to release electrons when the thermionic emitter is heated by the cathode heater. At least a portion of the second component of the cathode heater may be in contact with the thermionic emitter.

  • Processes for catalytically reforming naphtha
    Patent number: 9303217
    Abstract: Disclosed herein is a process for catalytically reforming naphtha, comprising, in the presence of hydrogen gas, contacting naphtha with at least one reforming catalyst under the conditions of a pressure ranging from 0.15 to 3.0 MPa, a temperature ranging from 300 to 540° C., a volume space velocity ranging from 2.1 to 50 h?1, to carry out a shallow catalytic reforming reaction so as to achieve a naphthene conversion ratio of greater than 85 mass %, and a conversion ratio of paraffins to arenes and C4? hydrocarbons of less than 30 mass %.

  • Multimetallic reforming catalyst comprising platinum and tin, the preparation and the application thereof
    Patent number: 6780814
    Abstract: A multimetallic reforming catalyst and the preparation process thereof are disclosed. Said catalyst comprises the following components on the basis of mass percent: 0.01-2.0 of a Group VIII metal, 0.01-5.0 of a Group IVA metal, 0.01-10.0 of Eu, 0.01-10.0 of Ce, 0.10-10.0 of a halogen, and 63.00-99.86 of a refractory inorganic oxide. This catalyst has relatively high activity and selectivity, low carbon deposition rate and long lifetime for reformation of naphthas.
