black powdery material can be used for example as a moderately hydrophilic due to the nitrogen doping pigment for cement or a colorant tinting agent for uv sensitive polymers another possible application of such black powder is in agriculture the u s pat no 4 252 919 patent describes how distantly similar materials can be used as fertilizers and soil improving agents a further possible application of the carbonaceous powdery product can be found in the manufacturing of electrodes for lithium ion batteries or capacitors as well as adsorbents for hydrogen storage yet further possible application of the said material is relevant to metallurgy specifically to means of the introduction of nitrogen into cast iron in the spirit of for example the u s pat no 4 970 051 one more possible application of the said material is in the reclamation of tailing ponds as an adsorbent and a source of nutrients for further bio remediation 3a the said material can be further modified or activated by heating in an oxygen free atmosphere at temperatures ranging from 350 u00b0 c to 1500 u00b0 c with more preferable temperatures from 400 u00b0 c to 900 u00b0 c the activation process can occur either with venting the nascent gases mostly nh 3 and hcl out of the reactor or in a sealed reactor with no venting if the gases are vented the product is a high quality activated carbon which can be used.
