Use of activated fluid coke to remove organic contaminants from waste waters

摘要

This invention relates to a novel activated fluid coke composition, a method for forming same, and an improved process for removing organic material from waste water by contacting said waste water under adsorption conditions with said activated fluid coke. The activated fluid coke may be prepared by contacting fluid coke with a gaseous mixture containing steam at temperatures of at least about 1500 F. for a period of time sufficient to convert at least 35 weight % of the fluid coke to gaseous products. The activated fluid coke so formed preferably has a total surface area of at least 400 square meters per gram, and a pore volume of at least 0.20 cubic centimeters per gram. The large pore volume and large total surface area, along with the particle size, particle size distribution, particle shape, particle density and attrition resistance of the activated fluid coke, result in said activated fluid coke exhibiting excellent properties as an adsorbent, particularly for removing organic materials from waste water streams.
