Embodiment 1

[0040] First, add 15 parts of acetone and 0.45 parts of ferrocene into the preparation barrel and stir slowly with a stirring rod to completely dissolve the ferrocene; then add 42 parts of ethanol and 20 parts of petroleum ether and stir for 10-15 minutes to mix evenly. Finally, add 4.5 parts of cerium nitrate and stir to dissolve completely; then filter through 400-500 mesh filter to prepare additives, which can be used for preparing natural gas and metal cutting gas.

[0041] Inject 80 grams of the prepared catalyst into a natural gas steel cylinder, then flush 10 cubic meters of pipeline natural gas into the steel cylinder, and the two will naturally mix and gasify, that is, the natural gas metal cutting gas is prepared.

[0042] Natural gas (CH4) in light alkane fuel gas is currently the cheapest gas for cutting. Due to its slow combustion speed, low flame temperature, and correspondingly increased cutting preheating time, it is difficult to apply, and the calorific value ...

Embodiment 2

[0045] First, add 10 parts of acetone and 0.3 parts of ferrocene into the preparation barrel and stir slowly with a stirring rod to completely dissolve the ferrocene; then add 30 parts of ethanol and 15 parts of petroleum ether and stir for 10-15 minutes and mix well , and finally add 3.5 parts of cerium nitrate and stir to dissolve completely; then after filtering through 400-500 mesh filter, it is prepared as an additive, which can be used for the preparation of natural gas and metal cutting gas.

[0046] Inject 100 grams of the prepared catalytic synergist into the light alkane fuel gas steel cylinder, then flush 12 cubic meters of pipeline light alkane fuel gas into the steel cylinder, the two will naturally mix and gasify, that is, the light alkane fuel gas is prepared Alkane fuel gas metal cutting gas.

Embodiment 3

[0048] First, add 20 parts of acetone and 0.6 parts of ferrocene into the preparation barrel and stir slowly with a stirring rod to completely dissolve the ferrocene; then add 50 parts of ethanol and 25 parts of petroleum ether and stir for 10-15 minutes and mix well , and finally add 6 parts of cerium nitrate and stir to dissolve completely; then after filtering through 400-500 mesh filter, it is prepared as an additive, which can be used for the preparation of natural gas and metal cutting gas.

[0049] Inject 80 grams of the prepared catalyst synergist into the light alkane fuel gas steel cylinder, then flush 10 cubic meters of pipeline light alkane fuel gas into the steel cylinder, the two will naturally mix and gasify, that is, the light alkane fuel gas is prepared Alkane fuel gas metal cutting gas.

Abstract

The invention belongs to the field of fuel gas catalysts and particularly relates to a light paraffin fuel gas rare earth catalytic synergist, as well as a preparation method and an application thereof. The formula of the catalytic synergist comprises the following raw materials in parts by weight: 3-6 parts of cerium nitrate, 0.3-0.6 part of ferrocene, 30-50 parts of ethanol, 10-20 parts of acetone and 15-25 parts of petroleum ether. The catalytic synergist is prepared through the steps of preparing additives, mixing the raw materials and filtering. The catalytic synergist is safe, environment-friendly and stable, and the preparation method and the application are simple; a light paraffin fuel after the rare earth catalytic synergist is added is high in combustion flame temperature and high in combustion speed, and can reduce the cost; the application fields are wide; and the requirements on purity of the light paraffin and the like taking natural gas, coalbed gas, biogas (biomass fuel gas) after purification, propane gas, liquefied petroleum gas and the like as parent gas are lower, and the adding proportion is low.

Description

technical field [0001] The invention belongs to the field of gas catalysts, in particular to a light alkane fuel gas rare earth catalytic synergist and its preparation method and application. [0002] Background technique [0003] A gas catalyst is a chemical substance used to catalyze and support combustion gas. The gas catalyst is mixed with light alkane gases such as natural gas, coal bed methane, purified biogas (biomass gas), propane gas, liquefied petroleum gas, and coal bed methane to undergo complexation reaction, thereby changing the combustion method and combustion frequency of the gas. , combustion speed, wavelength, etc. to achieve energy conversion, and greatly increase the flame temperature during gas combustion, to achieve the purpose of increasing temperature and increasing efficiency. . [0004] The combination of catalysis and combustion technology has a long history, but the modern catalytic combustion technology is a new technology that emerges at the ...
