preparation example Construction

[0016] The invention provides a method for preparing a natural gas gain agent. First, prepare the required raw materials: rare earth metal compounds, solvents and transition metallocene compounds, wherein the solvent is composed of methanol, toluene, methyl tert-butyl ether, A mixture of cyclohexane, nonane, decane and water. Based on the total weight of raw materials, the amount of the rare earth metal compound is 0.1-5%, and the amount of the solvent and the transition metallocene compound can be adjusted appropriately. Preferably, the amount of the transition metallocene compound is 1 to 6 times the amount of the rare earth metal compound, and the rest is solvent. Add the rare earth compound and the transition metallocene compound into the solvent, stir and mix until the solution becomes clear, and the preparation of the natural gas enhancing agent is completed.

[0017] In the above preparation method, rare earth metal compounds and transition metallocene compounds with c...

Embodiment 1

[0024] Weigh 2 g of the mixture of lanthanum nitrate and cerium nitrate, 6 g of the mixture of nickelocene and acetylferrocene, and mix methanol, toluene, methyl tert-butyl ether, cyclohexane, nonane, decane, and water according to the molar ratio 4: 0.1: 1.2: 0.05: 0.2: 0.4: 0.3 was formulated into 92g of solvent. Add the lanthanum nitrate, cerium nitrate, nickelocene and acetylferrocene into the solvent, stir and mix until the solution becomes clear, and then the natural gas enhancing agent is obtained.

Embodiment 2

[0026] Weigh 0.1g of lanthanum nitrate and 0.6g of cobaltocene, and mix methanol, toluene, methyl tert-butyl ether, cyclohexane, nonane, decane, and water in a molar ratio of 5:0.05:0.9:0.15:0.3:0.4 : 0.4 is prepared into 99.3g solvent. Add the lanthanum nitrate and cobaltocene into the solvent, stir and mix until the solution becomes clear, and then the natural gas enhancer is obtained.

Abstract

The invention discloses a preparation method of a natural gas gaining agent, and the preparation method comprises the following step of: sufficiently mixing the following raw materials: a rare earth compound, a solvent and a transition metallocene compound, wherein the solvent is a mixture which comprises methanol, methylbenzene, methyl tert-butyl ether, cyclohexane, nonane, decane and water. The preparation method of the natural gas gaining agent, which is disclosed by the invention, is easy to operate; the natural gas gaining agent prepared through the method disclosed by the invention can fast increase the combustion temperature of a natural gas from being lower than 2000 DEG C to 3500 DEG C and enable the natural gas to be completely combusted in such a way that the natural gas used for welding is combusted after passing through the gaining agent, thereby effectively reducing the content of carbon monoxide and the like which are contained in smoke dust and a tail gas, reducing the environment pollution and reducing the welding and cutting costs. The invention also provides the natural gas gaining agent obtained according to the preparation method.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving fuel booster, in particular to a booster capable of increasing the combustion temperature of natural gas used for welding and cutting and a preparation method thereof. Background technique [0002] In the mechanical thermal cutting process, acetylene is generally used as the working gas. However, acetylene is a high-energy-consuming product, and it is a serious waste of resources and pollutes the environment. 2 S, CO and other harmful gases are harmful to human health. For this reason, countries all over the world are devoting themselves to finding new cutting gas to replace acetylene gas. In recent years, it has been found that using natural gas with methane as the main component as welding and cutting gas has obvious advantages in energy utilization and environmental protection. However, the theoretical combustion temperature of natural gas is less than 2000°C, which is not enough ...
