Embodiment 1

[0031] A preparation method of suaeda-based superfine powder briquetted activated carbon, comprising steps as follows:

[0032] (1) Pretreatment

[0033] Clean the extracted Suaeda salsa in an ultrasonic cleaner for 20 minutes under 400W power ultrasonic conditions, remove the cleaned Suaeda salsa, drain the epidermal water droplets, rinse repeatedly with distilled water for 5 times, wring out the water with clean gauze, and place on the Under the condition of 105°C, carry out blast drying for 3 hours to constant weight. The purpose of ultrasonic cleaning: to clean the soil carried by the roots and stems and leaves of Suaeda salsa, so that the microorganisms and secretions adhering to Suaeda salsa will fall off, which is more conducive to ultrafine pulverization;

[0034] (2) Superfine grinding

[0035] Take a certain amount of Suaeda salsa dried to a constant weight, put it into an air-flow ultrafine pulverizer for 30 minutes, pass it through a 200-mesh sieve by brush sievi...

Embodiment 2

[0047] A preparation method of suaeda-based superfine powder briquetted activated carbon, comprising steps as follows:

[0048] (1) Pretreatment

[0049] Clean the extracted Suaeda salsa in an ultrasonic cleaner for 20 minutes under 500W power ultrasonic conditions, remove the cleaned Suaeda salsa, drain the epidermal water droplets, rinse repeatedly with distilled water for 3 times, wring out the water with clean gauze, and place Under the condition of 120°C, carry out blast drying for 5 hours to constant weight. The purpose of ultrasonic cleaning: to clean the soil carried by the roots and stems and leaves of Suaeda salsa, so that the microorganisms and secretions adhering to Suaeda salsa will fall off, which is more conducive to ultrafine pulverization;

[0050] (2) Superfine grinding

[0051] Take a certain amount of Suaeda salsa dried to constant weight, put it into an air-flow ultrafine pulverizer for pulverization for 40 minutes, pass through a 200-mesh sieve by brush...

Embodiment 3

[0061] A preparation method of suaeda-based superfine powder briquetted activated carbon, comprising steps as follows:

[0062] (1) Pretreatment

[0063] Clean the extracted Suaeda salsa in an ultrasonic cleaner for 15 minutes under 450W power ultrasonic conditions, remove the cleaned Suaeda salsa, drain the epidermal water droplets, rinse repeatedly with distilled water for 4 times, wring out the water with clean gauze, and place Under the condition of 110°C, carry out blast drying for 4 hours to constant weight. The purpose of ultrasonic cleaning: to clean the soil carried by the roots and stems and leaves of Suaeda salsa, so that the microorganisms and secretions adhering to Suaeda salsa will fall off, which is more conducive to ultrafine pulverization;

[0064] (2) Superfine grinding

[0065] Take a certain amount of Suaeda salsa dried to a constant weight, put it into an air-flow ultrafine pulverizer for 35 minutes, pass it through a 200-mesh sieve by brush sieving, and...

Abstract

The invention relates to suaeda glauca ultrafine powder briquetting active carbon and a preparation method thereof. According to the method, suaeda glauca ultrafine powder is firstly crushed into drypowder; then, ZnCl2 and FeCl3 composite activation solution is used for activation; next, heating carbonization is performed; after the carbonization, acidification washing, drying and ultrafine crushing are performed to obtain the suaeda glauca ultrafine powder active carbon; shaping agents, auxiliary materials and additives are added into the suaeda glauca ultrafine powder active carbon; mixingand water adding pasting are performed; briquetting and shaping are performed to obtain the suaeda glauca ultrafine powder briquetting active carbon. The suaeda glauca ultrafine powder briquetting active carbon and the preparation method thereof have the advantages that the cost is low; the preparation efficiency is high; the product adsorption performance is good.

Description

technical field [0001] The invention relates to a Suaeda salsa activated carbon and a preparation method thereof, belonging to the technical field of preparation and application of bio-based activated carbon. Background technique [0002] Activated carbon has been widely used due to its developed pore structure and high specific surface area, but the use of activated carbon has been limited due to the high cost of preparation. However, the performance of the prepared activated carbon is quite different, and the preparation of activated carbon with low cost and good performance needs further research . Patent CN 107662919A discloses a method for preparing biomass-molded activated carbon by dry method, which includes the following steps: (1) cleaning the sawdust, drying, then crushing, and passing through a 30-mesh sieve; (2) using the sawdust obtained in step (1) Sawdust and zinc chloride are mixed, ground, and passed through a 60-mesh sieve to obtain a mixture of zinc chlo...
