Apparatus for mixing cracking catalyst with a fluid hydrocarbon |
摘要 |
The present invention relates to a plug valve which effects the immediate and intimate mixing of fluidizable cracking catalyst with a fluid hydrocarbon in a riser reactor. Further, a stationary guide tube is located around a portion of the plug valve stem so as to define an upper and a lower annular compartment which are separated by a bushing. Bushings also define the upper end of the upper compartment and the lower end of the lower compartment. Each of the annular compartments has a bleed medium conduit connected thereto.
