Embodiment 1

[0025] Example 1: Introduce the pulverized plastic particles and graphite into the furnace cavity of the combustion furnace, and then pass in oxygen to adjust the carbon-oxygen molar ratio to 1, the high-temperature carbonization zone is 2000 degrees, and the low-temperature zone is 450 degrees. Exhaust gas processor (i.e. exhaust gas collection device), at the same time for exhaust gas treatment, the exhaust gas is mainly carbon dioxide and water vapor. After the combustion is completed, wait for the furnace body to cool down and collect the charcoal ash. The charcoal ash is deposited on the combustion furnace wall and is collected by sweeping with a tool. After the collected charcoal is extracted with toluene, it is separated and purified by a chromatographic column for separating fullerenes. According to the actual separated products, 10 kg of carbon ash can be produced per ton of plastic, and 50 g of C can be obtained from each kg of carbon ash. 60 (purity greater than 9...

Embodiment 2

[0026] Example 2: Introduce the pulverized plastic particles and graphite into the furnace cavity of the combustion furnace, and then pass in oxygen, adjust the carbon-oxygen molar ratio to 0.5, the high-temperature carbonization zone is 2100 degrees, and the low-temperature zone is 400 degrees. Exhaust gas processor (i.e. exhaust gas collection device), at the same time for exhaust gas treatment, the exhaust gas is mainly carbon dioxide and water vapor. After the combustion is completed, wait for the furnace body to cool down and collect the charcoal ash. The charcoal ash is deposited on the combustion furnace wall and is collected by sweeping with a tool. After the collected charcoal is extracted with toluene, it is separated and purified by a chromatographic column for separating fullerenes.

Embodiment 3

[0027] Example 3: Introduce the pulverized plastic particles and graphite into the furnace cavity of the combustion furnace, then pass in oxygen, adjust the carbon-oxygen molar ratio to 1.5, the high-temperature carbonization zone is 1900 degrees, and the low-temperature zone is 500 degrees. Exhaust gas processor (i.e. exhaust gas collection device), at the same time for exhaust gas treatment, the exhaust gas is mainly carbon dioxide and water vapor. After the combustion is completed, wait for the furnace body to cool down and collect the charcoal ash. The charcoal ash is deposited on the combustion furnace wall and is collected by sweeping with a tool. After the collected charcoal is extracted with toluene, it is separated and purified by a chromatographic column for separating fullerenes. According to the actual separated products, 10 kg of carbon ash can be produced per ton of plastic, and 50 g of C can be obtained from each kg of carbon ash. 60 (purity greater than 95%) ...

Abstract

The invention discloses a preparation method of fullerene, which comprises the following steps of: grinding plastic; mixing the ground plastic particles with a carbon-containing substance and a combustion-supporting gas at a predetermined temperature and burning; carbonizing the plastic particles at 1,900-2,200 DEG C in a high-temperature carbonization area, and collecting the charcoal ash formed after the carbonization in a low-temperature area at 400-500 DEG C; and separating and purifying the charcoal ash to obtain fullerene. According to the invention, fullerene is prepared by taking a carbon-containing waste substrate as a raw material, thus the waste is sufficiently utilized, the production cost of fullerene is lowered, and relatively great market value is created.

Description

technical field [0001] The invention relates to the field of preparation of fullerene materials, in particular to a preparation method of fullerene. Background technique [0002] with C 60 The representative fullerene is a multifunctional material. Its highly symmetrical closed-shell football-like molecular structure determines its unique physical and chemical properties. Fullerene derivatives have a variety of unique properties. Fullerene and its derivatives can be widely used in industrial catalysis, lubricating oil additives, composite materials, solar cells, cosmetics and other industries, with broad market prospects. In the foreseeable future, with the continuous improvement and development of fullerene synthesis and preparation technology and the continuous reduction of cost, the application of fullerene will become more common. [0003] However, the current production of fullerenes is still far from meeting the needs of the industry. The existing production methods ...
