MANUFACTURING METHOD OF ACTIVATED CARBON FROM HIGH CARBON CONTENTS FLY ASH BY USING COMBINATED BENEFICATION PROCESS

摘要

The present invention after air classification, separating the non-drawn high-quality minutes from the fly ash by a complex purification step to flotation, and as high due to the complex purification process to enable it relates to a process for the preparation of activated carbon from the carbon fly ash, minutes advance from fly ash as separation to produce an activated carbon to activated water vapor the method, (1) after the classifying air by the fly ash to the air classification method, separated by air classification number of the first number of pine oil or methylisobutyl the water back to the foaming agent-butyl carbinol (MIBC; methylisobutylcarbinol) to use, and complex purification steps by complex purification process for collecting waste oil or diesel oil by flotation collected secondary use the recovered water as a scavenger; (2) carbonization step of carbonizing the second recovered water obtained in the complex purification steps; It characterized by including the yirueojim and (3) a carbide carbide in the carbonization step activation step of steam activation.
