Carbonic and Mineral Adsorbent, Produced of Slurry Withdrawal of Oil-Extracting Production

The article considers the use of withdrawal of oil-extracting production as the initial material for receiving the adsorbent. The withdrawal is the diatomaceous earth (kieselguhr), which represents waste filtering material, formed as a result of cleaning vegetable oils. It also represents the slime, impregnated with vegetable oil and vegetable waxes (their content varies from 15 up to 70%). Now the fulfilled filtering materials are not utilized but they are taken out to dumps, that leads to environmental pollution and irrevocable losses of valuable components. The carbonic and mineral adsorbent is received as a result of carbonization of waste kieselguhr slime. The influence of carbonization temperature on physico-mechanical and sorbtion properties of the received sorbent is also shown. The valuation of sorbtion properties of carbonic and mineral adsorbent has shown that the maximum sorbtion capacity as on blue methylene is 2,2 mg/g, as on ions of Ni (II) is 17 mg/g, possesses carbonic and mineral adsorbent (CMA), received at temperature of 470 °C.
