Problems solved by technology

Because acetylene cylinders are in circulation, no manufacturer is willing to add acetone for himself or others, resulting in insufficient filling of acetylene gas, short of catties, and potential high-pressure explosion hazards. This problem has attracted great attention from relevant state departments.
However, the efficiency and quality of using gas such as liquefied petroleum gas for cutting and welding metal materials is not as great as that of acetylene gas.
The use of liquefied petroleum gas in non-ferrous metal smelting, roasting and roasting of various gas-fired boilers and kilns, commercial and civil stoves cannot be completely combusted due to the oxygen in nature, and the efficacy of gas is not fully utilized.
The key is that the gas is not activated, the explosion limit is too narrow, there is no activity, and it does not contain active oxygen, resulting in incomplete combustion, polluting the environment, and wasting limited resources

Embodiment 1

[0011] Transport 5,000 grams of steel cylinder 1 with a volume of 12 liters to the gas filling station to fill with 1,500 grams of mother liquor (the mother liquor is liquefied petroleum gas), and use a plastic spoon to put 0.6 grams of catalyst copper oxide powder into the drain on the angle valve 2 on the top of the cylinder. At gas port 6, connect a special filling gun and open the safety valve 4 of the steel cylinder, inject 80 grams of petroleum ether into steel cylinder 1 with a liquid filling gun (the catalyst follows into it), and then inject 800 grams of hydrogen peroxide into steel cylinder 1. At 0°C, 3% antifreeze ethanol needs to be added, and the safety valve 4 is closed to obtain 2380.6 grams of the required "high-efficiency liquefied petroleum gas", such as Figure 1-3 As shown, the steel cylinder 1 containing high-efficiency liquefied petroleum gas is provided with two angle valves 2, which are respectively used for exhaust and liquid discharge. One angle valve ...

Embodiment 2

[0013] Transport 5,000 grams of steel cylinder 1 with a volume of 12 liters to the gas filling station to fill with 2,000 grams of mother liquor (the mother liquor is propane), and use a plastic spoon to put 1.0 grams of catalyst manganese, neodymium, iron alloy powder into the cylinder angle valve exhaust port 6, Connect the special filling gun and open the angle valve 2 of the steel cylinder, inject 100 grams of gasoline into the steel cylinder 1 (the catalyst follows into it), and then inject 1000 grams of hydrogen peroxide into the steel cylinder 1. When the temperature is -40 ° C, it is necessary to add 5% anti Refrigerating agent ethanol, close angle valve 2, promptly make required " efficient liquefied petroleum gas " of 3101 grams.

Embodiment 3

[0015] Transport 5,000 grams of 12-liter liquid-phase steel cylinder 1 with a metal intubation to the filling station and add 1,800 grams of mother liquor (the mother liquor is propylene), and use a plastic spoon to add up the catalyst manganese-neodymium-iron alloy powder and copper oxide. Put 0.8 grams into the cylinder angle valve exhaust port 6, connect the special liquid gun and open the cylinder angle valve 2, inject 90 grams of petroleum ether and gasoline into the cylinder 1 (the catalyst follows into it), and then add hydrogen peroxide 900 gram into the steel cylinder 1, when the temperature is below -20°C, 4% antifreeze ethanol needs to be added, and the angle valve 2 is closed to obtain 2790.8 grams of the required "high-efficiency liquefied petroleum gas".

Abstract

The invention relates to a high-efficient liquefied petroleum gas which is characterized in that 2380.6 g-3101 g of the high-efficient liquefied petroleum gas comprises the following raw materials: 1500-2000 g of mother liquor, 80-100 g of petroleum ether or gasoline, 800-1000 g of hydrogen peroxide with a content (mass percent) of 27.5%-35%, and 0.6-1.0 g of catalysts of manganese neodymium iron alloy powder or copper oxide powder. The preparation method comprises the following steps: adding the catalyst of manganese neodymium iron alloy powder or copper oxide powder, and petroleum ether or gasoline into a steel cylinder with the mother liquor; injecting hydrogen peroxide into the steel cylinder, adding 3%-5% of antifreeze ethanol when the temperature is 0 DEG C-40 DEG C. The preparation method is simple, less in pollution, and low in energy consumption; the liquefied petroleum gas is high in contents of activated and gasified substances, less in harmful substances, and high in activity coefficient, and contains active oxygen to allow the gas to combust more completely; oxygen supply is performed for three times, which provides a combusting flame temperature of up to 3100 DEG C-3400 DEG C, and allows the gas to combust completely to generate only water and carbon dioxide; no environment pollution is caused; and the liquefied petroleum gas is a truly clean, safe, high-efficient fuel.

Description

technical field [0001] The invention relates to a high-efficiency liquefied petroleum gas and a preparation method thereof, in particular to a high-efficiency liquefied petroleum gas with super oxygen activity and a preparation method thereof, belonging to high-efficiency and energy-saving fuels. Background technique [0002] At present, the cutting and welding gas used for metal materials in my country is still mainly dissolved acetylene gas, but the production and use of acetylene gas seriously pollute the environment, and the process is cumbersome and complicated. When the acetone in the steel cylinder is released, it is gradually discharged, and the activated carbon in the steel cylinder is gradually exposed to the acetone, so that it cannot absorb acetylene gas, which cannot be compressed, and finally becomes "high-pressure acetylene". Since acetylene cylinders are in circulation, no manufacturer is willing to add acetone for himself or others, resulting in insufficient...
