example 1

[0011] Add 2-4Kg of petroleum coke into the solidified bed, and then raise the temperature to about 200 degrees under the condition of vacuuming the oil pump for half an hour, fill with nitrogen to drive out the air, and repeat three times. Raise the temperature of the reaction kettle to 500-600 degrees, slowly introduce fluorine gas, control the flow rate of fluorine gas added by a fluorine gas flow meter to be 100-300 ml / second, continue to react for 6-10 hours, stop heating, let The temperature of the reaction kettle is naturally cooled to room temperature, and nitrogen gas is passed into the reaction kettle after cooling to room temperature to drive away residual fluorine gas in the reaction kettle, and the reaction ends. During the reaction process, the gas outlet after the reactor is connected to two absorption towers equipped with potassium hydroxide or other lye to absorb complete fluorine gas. Open the reaction kettle and take out the solid powder in the solidified be...

[0013] Add 2-4Kg of petroleum coke into the solidified bed, and then raise the temperature to about 200 degrees under the condition of vacuuming the oil pump for half an hour, fill with nitrogen to drive out the air, and repeat three times. Raise the temperature of the reactor to 300-500 degrees, slowly introduce fluorine gas, control the flow of fluorine gas to 100-300 ml / second through the fluorine gas flowmeter, continue to react for 4-8 hours, stop heating, let The temperature of the reaction kettle is naturally cooled to room temperature, and nitrogen gas is passed into the reaction kettle after cooling to room temperature to drive away residual fluorine gas in the reaction kettle, and the reaction ends. During the reaction process, the gas outlet after the reactor is connected to two absorption towers equipped with potassium hydroxide or other lye to absorb complete fluorine gas. Open the reaction kettle and take out the solid powder in the solidified bed, most of which ...

example 3

[0015] Add 2-4Kg of graphite into the solidified bed, heat up to about 200 degrees under the condition of vacuuming by the oil pump for half an hour, fill with nitrogen to drive out the air, and repeat three times. Raise the temperature of the reactor to 500 to 600 degrees, slowly feed the mixed gas of fluorine gas and nitrogen gas with a ratio of 1:1, and control the flow of fluorine gas added to 100-300 ml / second through the fluorine gas flow meter, continue React for 6-10 hours; then stop heating, allow the temperature of the reactor to cool down to room temperature naturally, feed nitrogen into the reactor after cooling to room temperature, drive away the residual fluorine gas in the reactor, and the reaction ends. During the reaction process, the gas outlet after the reactor is connected to two absorption towers equipped with potassium hydroxide or other lye to absorb complete fluorine gas. Open the reaction kettle, take out the solid powder in the solidified bed, the col...

Abstract

The present invention is large scale synthesis process of carbon fluoride as one new type of functional material. Carbon fluoride material is white or grey, non-toxic, nonflammable, non-corrosive and chemically stable. It may be used as insulating material, waterproofing material, lubricant material and electrode material for high energy lithium battery, and has excellent performance and superiority of being used in the conditions of high temperature, high pressure, high load, strong acid and alkali environment. Carbon fluoride material is prepared through introducing fluorine gas or mixed gas of fluorine and nitrogen or other inert gas into special solidifying bed with various kinds of carbon process so as to produce reaction in certain temperature to generate carbon fluoride product of different sizes.

Description

technical field [0001] The series of fluorocarbon products are a new type of functional materials with a wide range of uses; they are usually white or gray, non-toxic, non-flammable, non-corrosive, and stable in chemical properties. They are good insulating materials, waterproof materials, and lubricating materials. ; It can be used as an electrode material for a new type of high-energy lithium battery. This type of battery is very prominent in terms of high energy, safety and stability, longevity, energy saving, and environmental protection. It is a new generation of safe, energy-saving and environmentally friendly high-energy batteries; it is also It has better lubricity than solid lubricants such as graphite and molybdenum disulfide, especially under harsh conditions such as high temperature, high pressure, high load and strong acid and strong alkali environment. It can be widely used in high-speed aircraft, launch vehicles, missiles , tanks, automobiles, etc. as lubricants...
