2 Analysis report Report L Date : 23/05/16 Contact person: Pascale Le Guerroue Pascale.Le.Guerroue@cedre.fr Request on testing Company: Mobius Group LLC Contact person: Vitaliy Fesenko and Nazar Burban Purpose: Determinate retention properties of the product Carbon Adsorbent The case: 29/04/16 Performer: Pascale Le Guerroue Approved Samples Type / Origin: floating adsorbent Receipt of samples: 19/04/16 Report Read: J.Giomarsh Approved Quantity: 2 sacks of 3 kg External distribution:: Möbius Group LLC 1 copy in pdf Inside copy : A&M Service: 1 Privacy: Х Conclusion Conclusion Tests in the laboratory allow to obtain the following results: Product Carbon Adsorbent in powder form is hydrophobic (ratio Cr water / Cr saturation is below than 0.25). It maintains, however, 0.02 times from his balance water. Due to the difference that exists between C r saturation and Cr 90% of this product has good capillarity. According to standard NFT , the product holds, at saturation, 4,0 ± 0,3 times from his balance hydrocarbons, as required, given the estimated volume density 0.127, volume saturation Tests have been conducted on hydrocarbons referred to in the link, the viscosity of which is from 42 to 45 cp at 20 C, showing that the product adsorbing Carbon Adsorbent WMS is to be recommended as an adsorbent for pollution floating medium viscosity hydrocarbons on the surface. 2

6 5. Notes : 5.1. Capabilities of retention in relation to hydrocarbon Laboratory tests proved that: Conventional point at Cr 90%, point at which main hydrocarbons are well seized by adsorbent (losses during drainage are only 10% of incipient hydrocarbon) is 4,3. Capability of retention while saturated in vase is 4,0. Capability of retention while saturated in volume or Cr of saturation (volume) is 0,57 (calculated considering the estimated density of adsorbent) Capabilities of retention in relation to water In the same testing conditions, when contacting water, product Carbon Adsorbent absorbs water 0,02 times its weight. Relation Cr water/cr saturation is 0, Accuracy of calculations Retention of hydrocarbons Saturation threshold is determined by the interval, which corresponds to the following terms: (r₁-r₂) / [ (r₁+r₂))/₂] = 0,61( 0,1) Given parameters give an opportunity to check whether the saturation threshold was achieved Confidence interval of 95%, according to Student s Law, of Cr saturation is ± 0,3 Error bars are 7,0% ( 10%). Water retention Results at the level of relation Cr water/cr saturation for different observations have a deviation of 0,04 points in relation to the mean value. 6

7 6. Conclusion Product Carbon Adsorbent in a powder appearance is hydrophobic (relation Cr water/cr saturation is less than 0,25). Nevertheless, it retains water 0,02 times its weight. Considering the difference between Cr saturation and Cr 90%, this product has a good capillarity. According to NFT standard, this product retains, while saturated, hydrocarbons 4,0 ± 0,3 times its weight, which is 0,57 saturation volume, taking into account approximate bulk density 0,127. Test conducted with hydrocarbon, mentioned in a reference, which viscosity is cp at 20 С, shows that adsorbing product Carbon Adsorbent can be recommended as a floating adsorbent for hydrocarbon contamination of a medium viscosity on the water surface. 7
