ABSTRACT:
Nitrogenous compounds especially bases such as amines are used to control the operation of a hydrocracker. Catalyst activity and selectivity may be controlled by addition of the base to the feed, for example, to control the balance between isomerization and conversion in an operation using a zeolite beta catalyst. Runaway conditions may be controlled by the addition of nitrogenous compounds and if they are added at intermediate points along the length of the reactor, the temperature profile within the reactor can be effectively regulated.
