Abstract
1523210 Start-up and shut-down procedures for hydroprocessing reactors CITIES SERVICE RESEARCH & DEVELOPMENT CO 10 Dec 1976 [17 Dec 1975] 51746/76 Heading C5E A start-up or shut-down procedure for an upflow ebullating bed reactor comprises circulating an initial charge of light oil and hydrogen through the reactor and progressively replacing the light oil by the heavy oil feed as the reactor temperature is increased (or vice versa for shut-down) with the ratio of light oil to heavy oil feed and the temperature being altered in a correlation such that the viscosity and density of the changing feed are maintained within + 20% of the starting viscosity and – 10% of the starting density during start up (or within -20% of the starting viscosity and + 10% of the starting density during shut down) whilst the liquid is pumped at constant rate to circulate in the reactor and ebullate the bed. The charge of catalyst in the reactor is initially heated by passage of hot gas.
