A two-step process for hydrogen production from vacuum residue

A two-step process has been developed for the conversion of vacuum residue to hydrogen. The first step involves oxidation of the vacuum residue in liquid phase at 373–423 K using ozone. The partially oxygenated products are utilized for hydrogen production by catalytic oxidative steam reforming over...

Summary:A two-step process has been developed for the conversion of vacuum residue to hydrogen. The first step involves oxidation of the vacuum residue in liquid phase at 373–423 K using ozone. The partially oxygenated products are utilized for hydrogen production by catalytic oxidative steam reforming over 2 wt% Pt/Al 2O 3-La 2O 3-CeO 2 catalyst. This two-step process reduces the formation of coke on the catalyst surface. Results show that it is a viable and technically feasible method for production of hydrogen from vacuum residue.
