摘要: Catalyst particles are presulfided in a pretreatment zone separate from a hydroconversion reaction zone. The presulfided catalyst is then added to a moving bed of catalyst in the hydroconversion reaction zone at reaction pressure, so that the reactor is not shut down to replace catalyst. The presulfiding process is particularly beneficial for use in moving bed reactors for heavy oil conversion.

摘要: In an expanded bed reactor, the expansion of the bed is automatically controlled by automatically changing the rate of speed of a recycle pump for the reactor. The bed is preferably provided with both high and low level bed detectors, and a further detector for determining abnormally high levels.
