Example Embodiment

[0013] Example 1.

[0014] Select the oil-tea camellia husk and place it in a constant temperature electric heating drying box to reduce the dry moisture content to 6%. The pretreated husk is further crushed to 60 mesh, and the oil-tea husk powder and 80% phosphoric acid solution are in a weight ratio of 1:2.5. Stir and mix evenly After standing for 24 hours, the acid-leached camellia husks were heated and carbonized in a 250°C dry box for 80 minutes; the carbonized camellia husks were placed in a resistance furnace and the temperature was increased to 550°C for 60 minutes; after cooling, the activated carbon Take it out, add clean water and wash repeatedly, make the pH value 7 and dry it in a drying box at 100°C to make the activated carbon have a moisture content of 3%. After crushing and sieving, the finished product of the camellia husk activated carbon is obtained.

[0015] According to the national standard GB / T 12496.10-1999 and GB / T 12496.8-1999, the iodine adsorption value...

[0016] Example 2.

[0017] Select the oil-tea camellia husk and place it in a constant temperature electric heating drying box to reduce the dry moisture content to 5%. The pre-treated husk is further crushed to 80 mesh, and the oil-tea husk powder and 60% phosphoric acid solution are in a weight ratio of 1:3.5. Stir and mix well After standing for 48 hours, the acid-leached camellia husks were heated and carbonized in a drying oven at 150°C for 120 minutes; the carbonized camellia husks were placed in a resistance furnace and the temperature was increased to 650°C for activation for 120 minutes; after cooling, the activated carbon Take it out, add clean water and repeatedly wash, make the pH value 5 and dry in a 120°C drying box to make the activated carbon have a moisture content of 5%. After crushing and sieving, the finished product of camellia husk activated carbon is obtained.

Abstract

The invention discloses a method for preparing activated carbon by utilizing camellia oleifera shells. The method comprises the following steps: screening the camellia oleifera shells to remove impurities; mixing and soaking the shell particles and a certain proportion of activated agent; then firstly carbonizing, activating through secondary heating; and sequentially scouring, washing, drying and pelletizing the activated materials to obtain activated carbon. The activated carbon is prepared by the camellia oleifera shells which are obtained from leftovers in processing of camellia oleifera, thus source is sufficient; and the activated carbon is prepared by taking the camellia oleifera shells as raw materials and combining physical and chemical methods, is simple in process, good in stability, less in pollution, easy to regenerate, low in production cost, large in specific surface area and good in adsorptive property.

Description

technical field [0001] The invention relates to a method for preparing activated carbon by using camellia oleifera husk, and belongs to the technical field of activated carbon preparation. Background technique [0002] Activated carbon is a carbonaceous adsorption material with developed pore structure and large specific surface area. It has unique physical and chemical properties, such as strong adsorption capacity, high mechanical strength, good chemical stability, and easy regeneration. Therefore, it is used as a high-quality Adsorbents and catalyst supports are widely used in the fields of industry, agriculture, national defense, transportation, medicine and health, environmental protection and energy. The raw materials for traditional activated carbon preparation are mainly wood and coal. Due to the limited and decreasing domestic forest resources and the high price of coal, it is an urgent problem to be solved in the field of activated carbon preparation to seek cheap...
