Problems solved by technology

[0005] Natural gas (CH 4 ) As a welding and cutting gas, its flame temperature in oxygen is only 2000-2600°C. When used for metal cutting, the preheating time is long, the oxygen consumption is large, it is difficult to cut thick and thick materials, and the work efficiency is low. It is difficult to completely replace acetylene, propane, Propylene, LPG

Embodiment Construction

[0016] refer to figure 1 , the specific embodiment adopts the following technical scheme: its formula consists of: ethanol 42%, tetrahydrofuran 20%, petroleum ether 32%, cerium-aluminum composite rare earth catalyst 5.67%, dicyclopentadiene and iron 0.33%; its preparation The process is as follows: first, mix ethanol and petroleum ether evenly for later use; then add tetrahydrofuran into the reaction kettle, add dicyclopentadiene, iron and liquid cerium-aluminum composite rare earth catalyst into the reaction kettle for stirring, and mix them with the above mixed solution Mix; after standing for 4 hours, discharge the clear liquid through the drain valve on the side of the reaction kettle, and pour it into a plastic packaging barrel.

[0017] This embodiment has the following features:

[0018] 1. It fundamentally solves the long-standing fundamental problem that liquid additives cannot be added to natural gas or the effect is not obvious after addition.

[0019] 2. Solve th...

Abstract

The invention discloses a synergistic additive of natural-gas as welding and cutting gas, and relates to the technical field of the synergistic additives of the natural-gas as the welding and cutting gas, wherein a preparation process of the synergistic additive comprises the following steps: uniformly mixing ethanol with petroleum ether for later use; adding tetrahydrofuran into a reaction kettle, adding bis(cyclopentadienyl) iron and a liquid cerium-aluminum composite rare earth catalyst into the reaction kettle to stir, and mixing with the mixed solution after dissolving completely; and standing for 4 hours and discharging clear liquid through a liquid discharge valve at the side of the reaction kettle, and filling the clear liquid into a package bucket to obtain the synergistic additive. The synergistic additive combines a catalytic activation principle of the cerium-aluminum composite rare earth and special organic chemical materials to play roles of increasing the temperature and assisting the combustion in the natural gas, resisting against explosion and increasing the flame temperature of the combustion of the natural gas in oxygen. In addition, the synergistic additive can be gasified under certain pressure and mixed with the natural gas to increase the activity coefficient index of the natural gas and increase the temperature of the combustion of the natural gas in oxygen to about 3430 DEG C, which is at an advanced level in the industry. The synergistic additive can completely replace acetylene in cutting, welding, baking and flame spraying functions.

Description

Technical field: [0001] The invention relates to the technical field of natural gas welding and cutting gas synergistic additives, in particular to a natural gas composite rare earth synergistic additive and a preparation method thereof. Background technique: [0002] Since French scientists applied oxygen-acetylene gas to the field of metal cutting and welding more than 100 years ago, acetylene gas has become the main gas for metal welding and cutting in the world, and has made irreplaceable contributions to the Industrial Revolution and human technological innovation. [0003] Due to high energy consumption, high pollution, easy explosion and low safety factor in the production process of acetylene gas, there are many high emissions, high pollution and low safety in transportation, storage and use. Many countries are studying new energy-saving and environmental protection alternatives to acetylene. , low-carbon and safe new industrial gas, as early as the early 1990s in my ...
