The present invention relates to a heating device for exhaust gas in an internal-combustion engine, which is driven by using LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, the device consisting of a catalyst reactor reformer, an exhaust gas suction section and the second fuel supply device. The exhaust gas suction section is mounted for using oxygen included in the exhaust gas. When the heating device is driven, air and fuels are supplied to the catalyst reactor and the second fuel supply device via a single tube when the heating device is heated. The present invention provides with a heating device for exhaust gas capable of securing the durability of a heating device for exhaust gas and minimizing the amount of air supplied from the outside to the combustion reforming device by excluding carbon depositions in a tube due to a prolysis of LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, and a method for driving the device.

Heating device for exhaust gas in internal combustion engine

A heater has microchannels for uniform heating, and includes an upper plate having an inlet of material to be heated, a fuel inlet and an oxidant inlet. A lower plate has a heated material outlet and an exhaust gas outlet. A plurality of combustion thin plates and a plurality of heat transfer thin plates are alternately layered between the upper and lower plates. Each of the combustion thin plates and the heat transfer thin plates has an inlet hole of material to be heated, a heated material outlet hole, an oxidant hole, an exhaust gas hole, a fuel hole, and microchannels formed at respective corresponding positions. The upper plate is aligned with the combustion thin plate contacting the lower surface thereof, and the lower plate is aligned with the heat transfer thin plate contacting the upper surface thereof.

Micro channel heater for even heating

Disclosed herein is a method of preparing a palladium alloy composite membrane for hydrogen separation, including (a) providing a first metal coating layer on a porous support using a dry sputtering deposition process; (b) providing a palladium coating layer on the first metal coating layer using a dry sputtering deposition process; and (c) heat treating the palladium coating layer to form an alloy layer of palladium and the first metal.
