Problems solved by technology

[0005] The disadvantages of the traditional chemical method of manufacturing activated carbon are that the activator consumes a lot, the activation time takes a long time, the recovery rate is low, and the waste water and waste gas produced are harmful to the environment. A new preparation method is urgently needed

Embodiment 1

[0031] A method for preparing activated carbon by microwave chemical activation method using camellia oleifera husk as raw material, comprising the steps of:

[0032] Step 1: Take the camellia oleifera fruit and dry it naturally. After the first ten days of October, the oil content of the camellia oleifera fruit reaches the highest peak, which is the fully mature stage. Observe with the naked eye that the hair of the fruit peel will naturally fall off, and it will become smooth and bright, and crack at 10% After collection, it is placed in a ventilated place to dry naturally until the water content drops below 10%;

[0033] Step 2: Shelling the camellia oleifera fruit, washing the discarded husk to remove impurities, and drying, taking the seeds of the dried camellia oleifera fruit, collecting the exhaust gas husk, and cleaning the surface of the husk until the surface of the husk and internal sundries are completely removed, and finally placed in a drying device for drying at...

Abstract

The invention belongs to the technical field of activated carbon preparation, and particularly relates to a method for preparing activated carbon by taking camellia oleifera shells as raw materials through a microwave chemical activation method. The method comprises the following steps of: 1, taking camellia oleifera fruits, and naturally airing, wherein after the first ten days of October, when the oil content of the tea oil fruits reaches the highest peak, the tea oil fruits are in a complete mature period, peel and fuzz of the tea oil fruits naturally fall off and begin to become smooth andbright through naked eye observation, and the tea oil fruits are collected after 10% of cracks and then placed in a ventilated place to be naturally aired till the water content is reduced to 10% orbelow; 2, shelling the camellia oleifera fruits, taking waste fruit shells, washing with water to remove impurities, drying, taking seeds from the dried camellia oleifera fruits, and collecting the waste gas fruit shells. According to the invention, the design is reasonable, and the prepared activated carbon has the advantages of large specific surface area, high total pore volume, developed finepore structure, high adsorption speed, high adsorption capacity and the like; and the waste camellia oleifera shells are used as raw materials to prepare the activated carbon, so that the source of raw materials for producing the activated carbon is expanded, the production cost is reduced, the raw materials are simple and easily available, and resource recycling is realized.

Description

technical field [0001] The invention relates to the technical field of activated carbon preparation, in particular to a method for preparing activated carbon by microwave chemical activation using camellia oleifera shell as raw material. Background technique [0002] Camellia oleifera is a unique woody edible oil tree species in my country. Camellia oleifera fruit consists of two parts: camellia oleifera husk and seeds. Camellia oleifera husk accounts for more than 60% of the whole camellia oleifera fruit mass, and its components contain cellulose, hemicellulose, lignin and tannin and other substances. According to statistics, the country's existing Camellia oleifera cultivation area has reached 4 million hectares, and the annual output of Camellia oleifera fruit has reached more than 5.6 million tons, which will bring more than 3 million tons of Camellia oleifera husks. The nuts are used to be processed into tea oil, while the husks are often discarded as residues and have...
