The practical value of hydrolytic lignin

Lignin in consistency resembles sawdust substance, a conglomerate of different compounds, mono-and polysaccharides, organic acid, tar, ash, wax and other components.
The content of pure lignin in this matter reaches 40-88% and the percentage of solid carbon in hydrolytic lignin reaches 30%. This is a highly porous material with moisture content from 65 to 70%.

Physical and chemical characteristics of hydrolytic lignin contributed to a number of studies intended to developing the options for the extended use of the substance in chemical, energy and metallurgical industries.

The thermal qualities of the substance are 5000-6500 kcal / kg, the ignition temperature of 195 degrees Celsius, the spontaneous ignition temperature is 450 degrees. At a pressure of about 100kPa lignin can be converted into a viscous substance, it can be used in the manufacture of briquettes.

In addition, it has a high calorific value and it doesn’t fume, replacing coke many of the reducing agents in chemical industry.

Systematizing the spheres of the use of hydrolytic lignin, they are the following:
1) In energy sector:

- Production of fuel briquettes and fuel gas;

- Production of reducers for metals in the form of briquettes

2) In chemical industry:

- Sorbent for purification of industrial effluents;

- Medical sorbents

3) In agriculture:

- The production of organic fertilizers and herbicides;

- An additive to concrete in the asphalt business.
