Method of embrittling waste
Patent
·
OSTI ID:5766689
The instant invention relates to a method of converting the solid organic fraction of solid waste into a powdered fuel which comprises heating said solid organic fraction in an inert atmosphere for a time and at a temperature sufficient to embrittle said solid organic fraction without causing substantial decomposition, pyrolysis, or dry weight loss of said solid organic fraction, comminuting said embrittled solid organic fraction to a powder which is less than a predetermined particle size, and recovering said powder. The inert atmosphere will comprise less than 1% by weight oxygen and is preferably a mixture of carbon oxides and nitrogen. The embrittling process takes place at a temperature of at least 125/sup 0/ C, preferably from 150/sup 0/ C to 250/sup 0/ C and said embrittled solid organic fraction preferably comminuted to a predetermined particle size of less than 10 mesh.
