Description

Composite metal catalyst module, catalytic fuel abatement device and preparation method thereof

The invention relates to a composite metal catalytic module, a catalytic fuel abatement device and a preparation method thereof. Background technique

The existing internal combustion engines are mainly diesel engines and gasoline engines. The fuels are diesel and gasoline. It is difficult to fully burn diesel or gasoline in the internal combustion engine. The combustion exhaust gas contains carbon monoxide, nitrogen monoxide and other gases and a small amount of soot. On the one hand, the internal combustion engine consumes a lot of fuel, and on the other hand, it pollutes the environment.

To this end, many scholars and experts at home and abroad are committed to the research of fuels for vehicles, boats, civil and industrial. At present, there are two main treatment methods for fuel combustion: one is to treat the exhaust gas after combustion of the fuel, and the other is to treat the fuel itself. The goal is to make full use of the fuel and reduce the pollution of the exhaust gas to the environment. The CN1072107A patent application discloses a rare earth composite oxide type three-way catalyst and a preparation method thereof, which uses three kinds of carrier materials: Α. γ-alumina particles; Β. aluminosilicate particles; C. cordierite honeycomb carrier, Low-temperature catalysis and high-temperature catalysis of novel ternary (C0, HC, NOx) catalysts using rare earth metals and transition metals and alkaline earth metal oxides as active components, with good catalytic activity, suitable for industrial exhaust gas purification and leaded gasoline exhaust Purification. The British Eureka (No. 1 (1997) p27~28) introduces the use of magnetism to improve the combustion characteristics of fuel to improve the combustion of fuel.

After heating or burning, the yttrium is converted into yttrium oxide, which can increase the oxygen carrying capacity of the fuel; the element 锑 has anti-burning and lubricating effect; the elemental palladium can resist hydrogen poisoning; the elemental platinum can resist sulfur;

The rare earth can be selected from medium and heavy rare earth ore produced in southern China. The main component of the above noble metal is relatively inexpensive tin, and on the other hand, tin acts as a binder to fuse other precious metals into one.

When entering the combustion chamber of the engine, it is sufficiently mixed with the oxygen in the air to further fully burn. .

In the same way, the domestic fuel No. 97 gasoline was used as fuel. After two months of installation of the catalytic fuel emission reduction device E, the accumulated driving was 3,424km, and the total fuel consumption was 421.1 liters. The comprehensive fuel consumption per 100 kilometers was 12.3 liters, and the fuel consumption was reduced by about 23%. Exhaust gas is detected once a week, and the average exhaust emissions are C0-0.01g/km, HC- 0. 005/km, Ox—0. 001 g/km, PM2. 5—0. 0005g/km.

In the same way, the domestic fuel No. 97 gasoline was used as the fuel. After two months of installation of the catalytic fuel emission reduction device F, the cumulative driving cost was 4360km, and the total fuel consumption was 531. 9 liters. The comprehensive fuel consumption per 100 kilometers was 12.2 liters, and the fuel consumption was reduced by about 30%. The tail gas is detected once a week, and the average exhaust gas emissions are CO—0.03 g/km, HC—0.01 g/km, NOx—0.01 g/km, PM2. 5-0. 001 g/km.

A 2000-year-old Santana petrol engine sedan, in 2010, the exhaust gas detection failed. After installing the catalytic fuel emission reduction device E, the exhaust gas test passed smoothly in 2010, 2011 and 2012, and the exhaust gas test did not occur in 2013. Qualified phenomenon, take out the composite metal catalytic module in the catalytic fuel abatement device, burn it on the natural gas flame for 5 to 10 seconds, cool to room temperature, replace the catalytic fuel abatement device, and reinstall it in the Santana sedan, exhaust The test is immediately qualified, and during the use of the catalytic fuel abatement device, the fuel consumption is reduced by an average of 20%, and the fuel-saving effect is obvious.

In 2009, Zhongtai 2008 version 1. 3 liters of gasoline engine sedan, originally had insufficient power, and the specific performance was three: 1. After the speed of the vehicle on the flat road was increased to 110km/h, the speed was obviously weak when the speed was increased; 2. The passenger inside the vehicle When full, the performance on the flat road is slow or slow, usually only two people in the car; 3. On the flat road, if the car air conditioner is turned on, the vehicle feels weak and the air conditioning cooling effect is poor.

After installing the catalytic fuel abatement device F, the passengers in the car are filled and the car air conditioner is turned on, and the vehicle can easily speed up to 130km/h, and the car air conditioning refrigeration effect is obvious.

Before the installation of the catalytic fuel abatement device F, the exhaust gas detection is often unqualified. Before the annual review, it is often necessary to replace the spark plug, the cleaning oil circuit and the deep maintenance to pass the annual review. After installing the catalytic fuel emission reduction device F, the year When testing exhaust gas, it is all qualified once.
