Startup method for a moving-bed hydrogenation zone |
摘要 |
A startup method for a moving-bed reactor used in a process for the hydrogenation of olefin-containing hydrocarbons. The reactor is brought on-stream at full capacity while it contains less than a full loading of catalyst, and quantities of catalyst are intermittently added to the reactor while the hydrocarbons are being processed. Catalyst removal is then begun at a rate lower than the rate of catalyst addition and adjusted when the catalyst retention volume of the reactor becomes filled.
