FUEL PROCESSING METHOD FOR SOLID OXIDE FUEL CELL SYSTEM

摘要

A fuel processing method performed in a solid oxide fuel cell system can completely remove a hydrocarbon remaining in a reformed gas, thereby preventing deteriorated fuel cell performance. The method comprises (a) removing sulfur from a hydrocarbon-based fuel and obtaining hydrogen-rich reformed gas using a desulfurizer that removes the sulfur and a primary-reformer that reforms the hydrocarbon-based fuel to generate the hydrogen-rich reformed gas; and (b) selectively decomposing a low carbon hydrocarbon of C2˜C5 contained in desulfurized reformed gas and converting it into hydrogen and methane using a post-reformer.
