Title: Method for regenerating activated carbon by electrification and electron donation
Inventor: IMAI MASAO
IPC: C01B31/08
Filed: 2008-12-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for regenerating activated carbon in a short time at normal temperature and under normal pressure by using a small quantity of water without using a chemical.  <P>SOLUTION: The activated carbon having an adsorbed component is electrified in such a structure that a pair of electrodes are composed of an inner pipe, which is arranged in the central part and consists of an electroconductive material in which the activated carbon is injected, and an outer pipe, which is arranged on the outside of the inner pipe and consists of the electroconductive material. The activated carbon and the adsorbed component in the inner pipe are electrified to have the same polarity. Simultaneously, an electron is donated to the electrified activated carbon and adsorbed component. As a result, the activated carbon and the adsorbed component repel each other and go to the directions dissociated from each other. Simultaneously, a chemical dissociation reaction is caused by electron donation. Since the outer pipe has different polarity, the metal-containing adsorbed component dissociated from the activated carbon is attracted and made to flow out of the inner pipe. Therefore, the activated carbon can be regenerated only by using normal water.  <P>COPYRIGHT: (C)2010,JPO&INPIT
