Embodiment 1

[0025] Take 1g of waste tire pyrolysis carbon black powder and put it into a paper bag sewn by filter paper, put it in the reflux tube of the Soxhlet extractor, put 100ml of toluene into the round bottom flask, carry out Soxhlet extraction for 8 hours, pass the liquid through The organic solvent was removed by rotary distillation, and the oil in the waste tire pyrolysis carbon black was collected. Remove the paper bag containing the sample to dry and collect the dried solid. Take 1 g of the solid and 30 ml of dilute sulfuric acid with a concentration of 0.1 mol / L and put them into a round bottom flask, stir at 30° C. for 0.5 hour, filter with suction, repeat the above steps twice, and finally dry the solid obtained by suction filtration. Take the dried solid and put it into a quartz boat, put it into the quartz tube of the electric tube furnace, connect a round bottom flask filled with distilled water at one end of the quartz tube, heat and boil the distilled water, and treat ...

Abstract

This invention relates to a method for preparing carbon-black and activated-carbon, by using waste-tyre as raw material after thermal decomposition and modification. The procedures are as follows: the carbon black from waste tyre is fed into a bag made from filter paper, extracted in flask with organic solvent; the solid is air-dried, weighing, the liquid is proceeded distillation for removing solvent, collecting the residul oil from the carbon black. The carbon black thus treated is put into a flask together with dilute acid, proceeded by agitation, vacuum filtering. The carbon black is then placed in quartz ship, and they are put in quartz tube, connected with flask with distilled water in it; heating the distilled water at 150-1000deg.C for treating the carbon black, drying, obtaining the final carbon black and activated carbon. Advantages are: reutilization of solvent and residual oil, utilization of dilute acid (less corrosion), high purity and high specific superficial area of final products.

Description

technical field [0001] The invention relates to a method for preparing carbon black and activated carbon through carbon black modification treatment, in particular to the preparation of carbon black and activated carbon through modification treatment of waste tire pyrolysis carbon. Background technique [0002] With the development of the automobile industry and the continuous renewal of automobiles, the disposal of waste tires has become an increasingly serious environmental problem, which not only causes a huge waste of resources, but also becomes a kind of "black pollution" that is more and more harmful. At present, pyrolysis of waste tires is one of the most ideal recycling methods. It recovers high value-added pyrolytic charcoal, oil, high calorific value gas and steel wire, etc., thereby fully recovering the precious resources of waste tires. The yield of waste tire pyrolysis charcoal is about 39%-44%. How to use this part of pyrolysis charcoal is the key factor relate...
