PROCESS FOR PREPARING SPHERICAL ACTIVATED CARBON GRANULE

摘要

A method for preparing spherical activated carbon granules is provided to improve the productivity of the spherical activated carbon granules, by rotating a mixture of pitch powder and carbon-based powder to form the spherical granules. Spherical activated carbon granules are prepared by using pitch as a starting source, and performing a rounding process, an oxidizing process, a carbonizing process, and an activating process. In the rounding process, spherical granules are formed by mixing pitch powder of no less than 120 mesh and carbon-based powder of no less than 200 mesh into each other and rotating the mixture while adding a water-soluble polymer solution into the mixture. Further, 60-90 wt.% of pitch powder is mixed with 10-40 wt.% of carbon powder.
