Problems solved by technology

If these carbon blacks are directly burned, they will cause incomplete combustion because of their rich moisture (water content is more than 95%); if they are used in rubber, paint and ink industries, they will affect product quality because of their powdery structure. And in the process of stacking, it will also cause serious environmental pollution

Embodiment

[0025] The invention discloses a renewable porous carbon adsorbent for toluene adsorption, whose raw materials are composed of carbon black and binder, which are prepared by roasting under the action of a pore-forming agent.

[0026] The mass ratio of the carbon black and the binder is 95:5, and the binder is flour paste.

[0027] The pore forming agent is (NH 4 ) 2 CO 3 aqueous solution, the (NH 4 ) 2 CO 3 The amount added is 20% of the total mass of carbon black and binder.

[0028] Simultaneously, the present invention also discloses a preparation method of a renewable porous carbon adsorbent for toluene adsorption, comprising the following steps:

[0029] S1: Precursor preparation: Grind massive carbon black and dry it in an oven at 70°C for 48 hours, weigh 0.05g flour into a crucible filled with 0.1ml deionized water, add 0.95g carbon black powder, and stir thoroughly , join (NH 4 ) 2 CO 3 Aqueous solution, (NH 4 ) 2 CO 3 The mass is 0.2g, fully mixed and sti...

Abstract

The invention discloses a renewable porous carbon adsorbent for toluene adsorption and a preparation method thereof. The renewable porous carbon adsorbent is prepared by roasting the following raw materials: carbon black and a binder under the action of a pore-forming agent. The porous carbon adsorbent PCBA with excellent toluene adsorption performance is successfully prepared by adhering the carbon-rich raw material carbon black through a binder and taking (NH4) 2CO3 as a pore-forming agent under high-temperature roasting, and the PCBA prepared by the method has a developed micro / mesoporous structure, so that more adsorption sites can be provided for toluene molecules, the adsorption efficiency is higher, and the prepared PCBA has a good application prospect. Resource utilization of the waste carbon black is achieved, application possibility is provided for VOCs adsorption of the waste carbon black, and resource utilization of carbon black resources and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of adsorbents, and in particular relates to a renewable porous carbon adsorbent used for toluene adsorption and a preparation method thereof. Background technique [0002] Volatile organic compounds (VOCs) are common air pollutants emitted in the petrochemical and chemical industries. Common VOCs mainly include: benzene series, aromatic hydrocarbons, aldehydes, ketones, and alkane compounds. These VOCs not only endanger the environment, such as water pollution, ozone depletion, and smog formation, but also pose a threat to human and animal health, causing acute or chronic poisoning of the nervous system, blood system, and immune system. High cancer risk. At present, the treatment technologies for VOCs mainly include adsorption, absorption, condensation, catalytic oxidation and photocatalysis, etc. Among them, the adsorption method is widely used because of its advantages of low treatment cost, simple proces...
