INREASING THE POTENTIAL OF ENERGY CROPS APPLICATION FOR HEAVY METAL CONTAMINATED AREAS


The use of biomass fuels is continually investigated, and the industry application possibilities are widely recognized. One of the determinants of energy crops cultivation is lack of competition with crops for consumption purposes. The production of biomass for energy purposes can be linked with the use of wastelands, degraded and heavy metals (chrome, lead, zinc, cadmium) contaminated areas through the use of energy crops with a phytoremediation potential. Gasification seems to be a good method of energy crops utilization due to the potential of retention in solid products of some heavy metals. This process also allows for the production of valuable gaseous fuel. Experimental research on the Miscanthus x giganteus gasification was carried out to determine the potential for agroenergetics to be used for active environmental protection. Fixed bed reactor was used. The maximum weight of the feedstock in the gasifier is 5 kg. To increase the potential of heavy metal accumulation in slag, the halloysite additive was used. The results of experimental studies present a significant increase of the lead share in slag.
