Method for preparing activated carbon by using cornstalks, coconut shells and shaddock peels

Abstract

A method for preparing activated carbon by using cornstalks, coconut shells and shaddock peels comprises the following steps: the cornstalks, the coconut shells and the shaddock peels are mixed according to a ratio, the mixture is dried and then smashed to obtain raw materials, the raw material particles are evenly mixed with an activating agent to obtain mixed materials, water is added to soak the mixed materials, the soaked materials are put into a microwave oven for carbonization activation, pickling, washing and drying are preformed, the dried raw materials are grinded, the grinded materials are screened through sieves with different meshes to obtain activated carbons with three levels of fineness, and the activated carbons with the three levels of fineness are mixed according to a ratio to obtain the final product. The activated carbon prepared according to the method has good absorption performance and is long in service life.

Description

technical field [0001] The present application relates to a method for preparing activated carbon, in particular to a method for preparing activated carbon by using corn stalks, coconut shells and pomelo peels. Background technique [0002] Activated carbon has become an extremely important adsorbent due to its well-developed internal pore structure, and is widely used in many fields such as water treatment, environmental protection, and agriculture. There are many raw materials for preparing activated carbon, including plant materials such as wood, chaff, and crop straw, as well as coal, petroleum coke, and rubber. In today's energy crisis and increasingly serious environmental problems, the use of cheap and abundant agricultural and forestry wastes to prepare activated carbon has attracted more and more attention. However, the existing process is usually relatively simple in the selection of agricultural and forestry waste raw materials, so the performance of the prepared...

Problems solved by technology

However, the existing process is usually relatively simple in the selection of agricultural and forestry waste raw materials, so the performance of the prepared activated carbon is relatively uneven, which is not conducive to the rational utilization of agricultural and forestry waste.
