Embodiment 1

[0015] A kind of activation method of bamboo charcoal is made up of following three steps:

[0016] The first step is the preparation of starch powder, according to the mass ratio m 玉米淀粉 :m 土豆淀粉 :m 莲藕淀粉 =100:35:1.5, the corn starch, potato starch and lotus root starch are uniformly mixed, and the particle size of the obtained starch powder is 80 meshes;

[0017] The second step is to prepare the modified bamboo charcoal, in the starch powder atomization air, the bamboo charcoal adsorbs the starch powder, and when the starch adsorption amount reaches 9% of the adsorption saturation of the bamboo charcoal, the bamboo charcoal is taken out to obtain the modified bamboo charcoal; wherein the bamboo charcoal is made of bamboo as Bamboo charcoal prepared from raw materials;

[0018] The third step is the activation of bamboo charcoal. The modified bamboo charcoal is placed in 900° C. steam, activated for 95 minutes, and cooled to room temperature under anaerobic conditions to obt...

Embodiment 2

[0020] A kind of activation method of bamboo charcoal is made up of following three steps:

[0021] The first step is the preparation of starch powder, according to the mass ratio m 玉米淀粉 :m 土豆淀粉 :m 莲藕淀粉 =100:40:3.0, uniformly mix corn starch, potato starch and lotus root starch to obtain a starch powder with a particle size of 100 mesh;

[0022] The second step is to prepare the modified bamboo charcoal. In the atomized air of the starch powder, the bamboo charcoal adsorbs the starch powder, and when the starch adsorption amount reaches 10% of the adsorption saturation of the bamboo charcoal, the bamboo charcoal is taken out to obtain the modified bamboo charcoal; wherein the bamboo charcoal is made of bamboo as Bamboo charcoal prepared from raw materials;

[0023] The third step is the activation of bamboo charcoal. The modified bamboo charcoal is placed in water vapor at 980° C., activated for 50 minutes, and cooled to room temperature under anaerobic conditions to obtain...

Embodiment 3

[0025] A kind of activation method of bamboo charcoal is made up of following three steps:

[0026] The first step is the preparation of starch powder, according to the mass ratio m 玉米淀粉 :m 土豆淀粉 :m 莲藕淀粉 =100:45:2.5, uniformly mix corn starch, potato starch and lotus root starch to obtain a starch powder with a particle size of 110 meshes;

[0027] The second step is to prepare the modified bamboo charcoal. In the starch powder atomization air, the bamboo charcoal adsorbs the starch powder, and when the starch adsorption amount reaches 12% of the adsorption saturation of the bamboo charcoal, the bamboo charcoal is taken out to obtain the modified bamboo charcoal; wherein the bamboo charcoal is made of bamboo as Bamboo charcoal prepared from raw materials;

[0028] The third step is the activation of bamboo charcoal. The modified bamboo charcoal is placed in water vapor at 1100° C., activated for 60 minutes, and cooled to room temperature under anaerobic conditions to obtain ...

Abstract

The invention discloses an activation method for bamboo charcoal. The method comprises the following three steps: a first step, preparing starch powder, to be specific, corn starch, potato starch and lotus root starch are uniformly mixed according to the condition that the quality ratio of m corn starch to m potato starch to m lotus root starch is 100:(30-45):(1.5-3.5), and the particle diameter of the prepared starch powder is 80-120 meshes; a second step, preparing modified bamboo charcoal, to be specific, bamboo charcoal adsorbs the starch powder in starch powder atomizing air, when the starch adsorbing quantity reaches 9%-14% of the bamboo charcoal adsorbing saturation quantity, the bamboo charcoal is taken out, and the modified bamboo charcoal is obtained; a third step, activating the bamboo charcoal, to be specific, the modified bamboo charcoal is placed in vapour of 900-1100 DEG C to be activated and processed for 25-95 minutes, and the modified bamboo charcoal is cooled to normal temperature under the oxygen-free condition, so that the activated bamboo charcoal is obtained. The activation method for the bamboo charcoal, disclosed by the invention, is easy to realize, convenient to operate and low in production cost.

Description

technical field [0001] The invention relates to a method for activating bamboo charcoal, in particular to a method for activating bamboo charcoal with starch mixed powder. Background technique [0002] Activated carbon is a kind of carbon material with developed pore structure, huge specific surface area and excellent adsorption performance, which has a wide range of important uses in all walks of life. With the development of the national economy, many fields have put forward higher requirements for the performance of activated carbon, which further promotes the development of activated carbon in terms of raw materials, production technology and performance. The preparation of activated carbon is a complex process that is affected and restricted by many factors. [0003] The raw materials for preparing activated carbon with excellent performance are very rich. Generally speaking, as long as it is a carbon-rich substance, it can be used as a raw material for the preparatio...
