preparation example Construction

[0030] The invention provides a method for preparing a waste zinc-manganese battery-biomass adsorbent, the specific steps are as follows:

[0031] Step 1, determine the amount of negative electrode material and hydrochloric acid: calculate and generate 2mol / L~3mol / L ZnCl respectively 2 The mass of the required negative electrode material and the volume of hydrochloric acid of 8mol / L~12mol / L; wherein the negative electrode material is converted according to the mass percentage content of 50%~60% of the tested Zn;

[0032] Among them, in the process of weighing the negative electrode material and hydrochloric acid, in order to make the adsorbent prepared by the preparation method of the present invention have better performance, there will be an excess of no more than 5% by mass, but it will not affect the entire preparation process;

[0033] Step 2, weighing of deionized water, positive electrode material and biomass: weigh the deionized water, positive electrode material and b...

Embodiment 1

[0050] Calculate and generate 2mol / L ZnCl respectively 2 The quality of required negative electrode material and the volume of the hydrochloric acid of 8mol / L; Wherein the mass percent content of the Zn that negative electrode material is tested is 50% and is converted, and the consumption of negative electrode material and hydrochloric acid is respectively 20g and 50ml; The mass and the quality of the negative electrode material are 2.5:1 to weigh 50ml of deionized water, the total mass of the positive electrode material and biomass and the sum of deionized water and hydrochloric acid are to weigh the positive electrode material and biomass according to the solid-liquid ratio of 1:4, the positive electrode The material and sawdust are 20g according to the mass ratio of 1:4, and the sawdust is crushed and mixed with the positive electrode material as a mixed raw material; the obtained negative electrode material is added to a 250ml flask, and 50ml of deionized water is added fo...

Embodiment 2

[0052] Calculate and generate 3mol / L ZnCl respectively 2 The quality of required negative electrode material and the volume of the hydrochloric acid of 12mol / L; Wherein the mass percent content of the Zn that negative electrode material is tested is 56% and is converted, and the consumption of negative electrode material and hydrochloric acid is respectively 20g and 50ml; The quality and negative electrode material quality are 3:1 to measure deionized water 60ml, the total mass of positive electrode material and biomass and the sum of deionized water and hydrochloric acid are 1:4 to weigh positive electrode material and biomass by solid-liquid ratio, positive electrode The material and peanut shells are taken at a mass ratio of 1:5 to take 30g, and the peanut shells are crushed and mixed with the positive electrode material to form a mixed raw material; the obtained negative electrode material is added to a 250ml flask, and 60ml of deionized water is added to carry out a 15min ...

Abstract

The invention discloses a preparation method of waste zinc-manganese battery-biomass adsorbent, according to ZnCl 2 The molar concentration of the negative electrode material and hydrochloric acid were weighed respectively, and the amount of deionized water and the quality of the mixed raw material of the positive electrode material and the pulverized biomass were determined according to the weighed negative electrode material and hydrochloric acid; the mixed raw material was activated in two stages under certain conditions ; Then the two-stage activated product is carbonized; the obtained carbonized product is repeatedly washed with distilled water until the pH is neutral, then placed in an oven to dry, and the dried sample is fully ground to prepare a waste zinc-manganese battery- Biomass adsorbent; a kind of waste zinc-manganese battery-biomass adsorbent prepared by the preparation method of the present invention, realizes the utilization of all components of waste batteries, and solves the problem of large consumption of chemical activators in the preparation of conventional adsorbents , and realized the recycling of waste batteries, biomass and other solid waste.

Description

technical field [0001] The invention belongs to the technical field of adsorbent preparation, and in particular relates to a method for preparing a waste zinc-manganese battery-biomass adsorbent. Background technique [0002] my country is the country with the largest battery production and consumption in the world. According to the statistics of the China Battery Enterprise Association in 2014, the production of alkaline zinc-manganese batteries alone reached 12.8 billion. Manganese-enriched zinc-manganese batteries are one of the important sources of waste batteries in my country. Traditional waste battery treatment methods, such as pyrometallurgy or hydrometallurgy, have limited their promotion and application in my country due to shortcomings such as high cost, secondary pollution, high safety risks and low product value. In 2016, the newly revised "Waste Battery Pollution Prevention and Control Technology Policy" announcement by the Ministry of Environmental Protection ...
