Purpose of the development: Method for obtaining nanostructured adsorbent for various industrial processes.

Recommended application field: Ecology and health, agriculture, food industry.

Technical characteristic: Rational parameters of the process for obtaining the adsorbent from plant waste (PB) and sulfuric acid (SC): - sulfuric acid - 65%, - РВ: СК = 1: 1,5; - the reaction time - 1.5 hours; - the process temperature - 130 ° C.

Advantages over analogues: Effective technology for obtaining nanostructured adsorbents will solve the problem of handling plant waste from the agro-industrial complex by obtaining the final products of a special purpose, which is competitive in the current market of industrial adsorbents.

The development stage readiness: tested in laboratory condition

Technical and economic effect: The cost price of the adsorbent (1 UAH / kg) is 10 times less than the cost of activated carbon. To get 1 ton of adsorbent, you need 1.2 tons of plant waste. For adsorptive cleaning of 1 ton of vegetable oil, 30 kg of adsorbent is consumed.

Description of the development:
()
To obtain an adsorbent with improved adsorption properties, the task was to grind the adsorbent to break the van der Waals forces that arise as a result of the electrostatic interaction of the dipoles. The grinding of the adsorbent in the PM-120 mill was carried out, the granulometric composition was 0.05-0.1 mm, the bulk density was 460 g / m3, and the humidity was 1.5%. Electron microscopy showed the presence of micropores measuring 0.5 nm, dispersity - 10 nm. The adsorption capacity of the obtained adsorbent was determined by purification of waste water from heavy metal ions. The degree of purification was 99.9%. Experimental samples of nano-adsorbents from inflorescences of sunflower, corn cobs, and nut shells have been obtained using an improved technique. The technology of adsorption purification of sunflower oil with the use of a modified adsorbent can be realized on the operating equipment of the refining shop of oil and fat plants by the standard technological scheme.
