Fuel processing device

摘要

Provided is a fuel processing device including: a combustion unit equipped with a heat source; a desulfurization unit for extracting a sulfur component from the source gas; a reforming unit for generating, from the desulfurized source gas, a hydrogen-containing gas having hydrogen as a main component thereof; and a low-temperature conversion unit equipped with an exothermic catalyst for reducing the impurity concentration in the hydrogen-containing gas. The reforming unit and the desulfurization unit are configured so as to surround the combustion unit, and are disposed concentrically in the given order facing outwards from the combustion unit. The present invention further includes a preheating passage which is connected to the desulfurization unit, and which is provided to a bottom part of the combustion unit via a heat insulation material, such that the source gas is preheated by heat from the combustion unit.

主权项

1. A fuel processing apparatus comprising:
a combustion section having a heat source; a desulfurization section that removes sulfur component from a source gas; a reforming section that generates hydrogen-containing gas having hydrogen as a main component from the source gas desulfurized; and a low-temperature conversion section having a heat-generating catalyst that reduces an impurity concentration in the hydrogen-containing gas, wherein: the reforming section and the desulfurization section are provided surrounding the combustion section, and the reforming section and the desulfurization section are formed in order in concentric circles from the combustion section toward outside, and the fuel processing apparatus further comprises a preheat flow channel provided at a bottom of the combustion section with an insulating material interposed in between and in communication with the desulfurization section, such that the source gas is preheated using heat from the combustion section.
