Method for preparing active carbon by utilizing tea oil seed hulls

Abstract

The invention discloses a method for preparing active carbon by utilizing tea oil seed hulls. The method comprises the following steps of: taking air-dried materials (tea oil seed hulls); soaking with mixed liquid of zinc chloride and phosphoric acid, fishing, drying in the air without water drops, heating to be 800-1100 DEG C in a sealed container at the temperature-rising speed of 4-8 DEG C / min, carbonizing, and controlling the carbonizing time to be 4-6h; cooling to room temperature, carrying out soaking and acid pickling by using hydrochloric acid solution, taking out, draining, and bleaching with deionized water to enable the pH value to be 7; after baking, cooling to room temperature, and obtaining granular active carbon. The method for preparing the active carbonhas the advantages that the waste (tea oil seed hulls) of agricultural products is utilized, so that the additional value of the agricultural products is improved and the pressure for protecting the environment is effectively reduced; and the process is simpler, the process flow is short and the promotion is easy.

Description

technical field [0001] The invention relates to a method for preparing activated carbon by using camellia oil seed shells. Background technique [0002] Due to the large population in China, a large amount of edible oil is consumed every year, and the proportion of edible vegetable oil extracted from peanuts, soybeans and tea oil seeds is the largest. Therefore, this type of plant is widely planted in China. After extracting the oil from the fruits of the above plants, the obtained oil cakes are of no great use. Some of them are used for feed or medicinal purposes, and some are used for retting, which seriously wastes these resources; while the tea oil seed shells after the fruits are removed are discarded. Direct discarding not only wastes available renewable resources, but also reduces the value of agricultural by-products. On the other hand, because activated carbon is a carbonaceous substance with developed pore structure, huge surface area and excellent adsorption per...
