COMBINATION PROCESS FOR UPGRADING REDUCED CRUDE

摘要

In a reduced crude conversion the catalyst is regenerated with mixture of oxygen-enriched gas and H2O either as steam or preferably as water to provide additional expansion and facilitate fluidization, while converting coke on catalyst to CO and H2 with minimum CO2 formation. The CO can be combined with hydrogen to produce methane, methanol or Fischer-Tropsch liquid hydrocarbons or can be passed through the reduced crude conversion operation as lift gas, or as cooling medium or subjected to water-gas shift to produce addition H2.
