Abstract: A liquid fuel combustion system is provided. The system comprises: a combustion stove, comprising a vaporization unit with a ring shape vaporization space, a burner assembly and a first pipeline; a liquid fuel storage tank, having a storage space; a second pipeline, having a third opening end open to the storage space and a fourth opening end open to the ring shape vaporization space; and a liquid fuel composition contained in the storage space, comprising a liquid fuel and an ignition promoter which provides a vapor pressure in the storage space, whereby the vapor pressure drives the liquid fuel composition to be delivered out the storage space through the second pipeline, vaporized in the ring shape vaporization space and then delivered by the first pipeline to the burner assembly.

Abstract: A hydrogen generator essentially composed of a first medium is provided, comprising: a reforming zone, a preheating zone and a heat source. The reforming zone is used for containing a reforming catalyst so as to perform a steam reforming reaction of a hydrogen-producing raw material to generate hydrogen; and the heat source provides heat to the preheating zone and reforming zone, so that the hydrogen-producing raw material is firstly preheated in the preheating zone and then performs the steam reforming reaction in the reforming zone. The reforming zone and preheating zone are divided with a shortest interval of at least about 0.5 mm with the first medium, wherein the first medium has a thermal conductivity (K) of at least about 60 W/m-K.

Abstract: A porous catalyst structure with a high specific surface area comprising a porous substrate with a catalyst layer thereon is provided. The porous catalyst structure can be prepared by a process comprising depositing a metallic layer onto the surface of a porous, metallic substrate by electroplating, and optionally oxidizing the metallic layer into the metal oxide layer. Any conductive porous metallic substrate can be used as the substrate of the subject invention, and the metallic layer may comprise any suitable metal(s) and/or metal oxide(s) with desired catalytic function(s).
