Abstract
A method for processing a gasoline range hydrocarbon stream wherein a single reactor/distillation tower stream is fractionated into a light fraction and a heavy fraction, the light fraction is hydrodesulfurized, the heavy fraction is optionally hydrocracked and then hydrodesulfurized, and the light and heavy fractions are separately recovered.
Claims14
A method for processing a hydrocarbon containing stream which is essentially in the gasoline boiling range comprising providing a unitary reactor/distillation zone, separating said stream into a light fraction, and a heavy fraction;
- hydrodesulfurizing said light fraction in said zone using a catalyst which is effective for hydrodesulfurizing and is not nickel based, hydrodesulfurizing said heavy fraction in said zone using a catalyst effective for hydrodesulfurization, and separately recovering the light and heavy fractions from said zone without mixing same.
