Hydrolytic lignin.

Lignin - organic material. It is a natural polymer and is included with of wood and plants.

Hydrolytic lignin - lignin extracted from wood as a result of hydrolysis.

The natural moisture of lignin in storage areas - 45-65%.

Specification of hydrolytic lignin (on dry basis).

1. Ash content - 0.8-7.0%

2. Group composition:

• lignin - 65-85%
• hard hydrolyzed polysaccharides - 12-30%
• hydrolyzable polysaccharides - 1.0-1.3%
• reducing agents - 2-4%
• substances extracted ethanol-benzene mixture - 6-8%

3. PH - 3.5-6.0

4. The content of humic substances of the complex - from 5% to 19%.

5. Elemental composition of lignin: C = 55 - 58%; H = 5,5 - 6,0%; S = 0,6 %; O = 35%; N = 1%.

6. Ash composition: Al2O3 - 1%; SiO2 - 93,4%; P2O5 - 1.5%; CaO - 1.5%; Na2O - 0.3%; K2O - 0.3%; MgO - 0.3%; TiO2 - 0.1%.

7. Calorific capacity - 5500-6500 kcal/kg.

8. Lignin particle density - 1.2-1.45 gr/sm³

9. High absorption capacity (water capacity) 300-450%.

Application examples of hydrolytic lignin:

• Biofuels;
• Water treatment;
• Adsorbent for the purification of industrial waste water and the adsorption of heavy metals;
• Powdered additive in road asphalt concretes;
• Component in the production of wood-plastic products (WPC);
• Production of natural plastic "liquid wood";
• Organic fertilizer.
