  • Method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine
    Patent number: 7132584
    Abstract: A method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine (TiOPc) comprises heating a mixture of titanyl phthalocyanine (TiOPc), a vitrifying material and optionally selected waste soil to a temperature of 1,220° C. to 10,000° C. until the mixture becomes a molten lava. The plasma breaks down the titanyl phthalocyanine and encapsulates the benign products in the lava that is chemically very stable. Since the titanyl phthalocyanine (TiOPc) is disintegrated completely in the process, the titanyl phtbalocyanine (TiOPc) no longer represents a threat to the environmental.

  • Melting plasma method for treatment of Alq3 organic waste
    Publication number: 20050049450
    Abstract: A melting plasma method for treatment of Alq3 organic waste has steps of (a) providing an organic waste comprising Alq3; (b) heating the Alq3 organic waste provided in step (a) by melting plasma; and (c) obtaining a non-toxic organic solid lava which does not have any Alq3.
