Abstract: A portable fluid delivering system is provided. The system comprises a container, a heat source, a flow rate regulating device and a delivery tube. The container has a containing space for a fluid to be delivered, in a liquid state at room temperature. The heat source provides an elevated vapor pressure in the containing space over the fluid to be delivered, whereby the fluid to be delivered is driven at a desirable rate along the delivery tube.

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).

Abstract: A fluid delivery device is provided. The device comprises an internal container, an external container and a first delivery pipe. The internal container has a first space for containing a fluid to be delivered. The external container substantially surrounds the internal container to form a substantially sealed second space between the internal container and the external container, wherein the second space is for an assistant liquid. The assistant liquid is heated to raise the pressure in the second space, and then, the internal container is pressed, thereby driving the fluid out along the first delivery pipe.

Abstract: A process for producing hydrogen is provided. The process comprises the introduction of reactants into a reactor with a steam reforming section containing a steam reforming catalyst to form a hydrogen-containing product. The process is driven by heat generated in a combustion section containing an oxidation catalyst, which comprises a noble metal and boron nitride. According to the process of the subject invention, the first combustion reaction can rapidly generate heat and is advantageous for conducting steam reforming reactions.
