    • A fuel reforming system includes an inlet device for a reactor having a housing defining a frustoconical interior region having an inlet opening and an outlet opening. A tube mixer having a helical divider may be optionally employed to transfer fluid into the inlet opening. A retention member is placed at each of the openings and a plurality of particles is contained within the frustoconical interior region between the retention members. An insulator placed between the outlet opening and the catalyst reaction surface minimizes temperature non-uniformities over the catalyst surface area, which preserves the catalyst contained within the reaction surface and prevents premature onset of the reaction prior to contact of a reactant mixture with the reaction surface. As a reactant fluid material passes through the inlet device it forms a homogenous reactant fluid material which then flows onto a catalytic reaction surface to form a reformate. Even distribution of the reactant fluid material onto the catalyst reaction surface provides uniform reactivity of the various components (e.g. fuel, air and exhaust gas mixture) comprising the reactant mixture, which helps reduce carbon build-up in the system and increases thermal efficiency.
    • 燃料重整系统包括用于反应器的入口装置,其具有限定具有入口开口和出口开口的截头圆锥形内部区域的壳体。 可以任选地使用具有螺旋分隔器的管式混合器将流体输送到入口开口中。 保持构件被放置在每个开口处,并且多个颗粒包含在保持构件之间的截头圆锥形内部区域内。 放置在出口和催化剂反应表面之间的绝缘体使得催化剂表面积上的温度不均匀性最小化,这保留了包含在反应表面内的催化剂,并防止反应混合物与反应表面接触之前的反应过早开始 。 当反应物流体材料通过入口装置时,其形成均匀的反应物流体材料,然后流入催化反应表面以形成重整产物。 反应物流体材料在催化剂反应表面上的均匀分布提供包含反应物混合物的各种组分(例如燃料,空气和废气混合物)的均匀反应性,这有助于减少体系中的碳积累并提高热效率。
