Abstract:
The present invention relates to a catalyst purification device for the engine of a vehicle capable of purifying ammonia slip using an ammonia oxidation catalyst (AOC) according to the structure of an exhaust gas path and a control method thereof. More specifically, the present invention can oxidize the ammonia slip used not to be oxidized to a catalyst or an SCR catalyst by purifying the ammonia slip of exhaust gas caused from an engine for a vehicle, which is operated by each of fuel for a spark ignition engine and liquid ammonia fuel or mixing them, using an AOC catalyst device according to the set conditions of a vehicle and the exhaust gas, and can emit the lower amount of NOX caused when ammonia is oxidized than the emission standard of harmful ingredients of the exhaust gas because the minimum amount of the NOX is emitted to the outside by purifying the NOX using a second catalyst device; thereby preventing environmental contamination. Also, the present invention can minimize the amount of the ammonia emitted to the atmosphere since the activation hours of the catalyst is reduced by positioning an AOC catalyst close to the engine with a primary catalyst, and can extend the life of the catalyst since the catalyst is protected by changing the path if there is a possibility that the AOC catalyst is damaged by the high temperature of the exhaust gas.
Abstract:
The present invention relates to a method for producing ammonia, wherein the ammonia is produced from water vapor and nitrogen gas supplied together, while carrying out a reforming process of hydrocarbon based fuel gas through a ion-conducting gas separation membrane by receiving oxygen absorbed in the reforming process of hydrocarbon based fuel gas from water vapor supplied to the opposite side to the side to which the hydrocarbon based fuel gas of the gas separation membrane is supplied through an ion permeation method. The method of the present invention comprises: a step of supplying hydrocarbon based fuel gas, while maintaining the temperature of 500°C to 700°C in a device for producing ammonia of which an inner space is divided into a first space and a second space by a gas separation membrane, which is a border, to allow one side of the gas separation membrane to contact with the first space; a step of supplying water vapor (H_2O) and nitrogen (N_2) gas with the pressure of 1 to 10 atm to allow the other side of the gas separation membrane to contact with the second space; a step of obtaining synthesis gas, which is a reaction product generated in the first space; and a step of obtaining ammonia which is produced in the second space. The method for producing ammonia of the present invention can produce ammonia from water vapor and nitrogen without electric energy supplied from outside as well as has an advantage of reforming hydrocarbon based fuel gas at the same time.
