Abstract: The pyrogenic process and wet process were used to eliminate the nocuous elements such as Cl, Zn which have negative effect on blast furnace operation in battery recycle. Results show that in the range of experiment, pyrogenic process can eliminate most of Cl but take no effect on Zn. Higher removal efficiency can be got at higher temperature and Cl was removed by 37% at 615 K. The removal effect of wet process is better than the pyrogenic process. The wet process can remove Cl by 85% and Zn by 30% in 15 min at 318 K. In the wet process, temperature and time have little effect on the results so it is convenient for industry application. Dry batteries treated by the wet process can meet the request standard of blast furnace operation so that they can be used as additives for pulverized coal injection.
