Specifically, the substance is heated at 150-350 deg.C for a period of time with the application of steam at a pressure of 0-1.5 megapascals in an autoclave or similar apparatus, comminuted in size below 5 mm mesh to give a sorptive capacity for oil and related compounds of 5-10 times its own weight. ADVANTAGE-The improved material exhibits ease of collecting sorbed oil from water using a strainer of nominal mesh size to effect 100% recovery with little uptake of water. The oil and related compounds can be separated from the sorbate by the application of pressure, centrifugal force, or by solvent extraction and/or distillation.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></record></records></xml>
