Abstract:
The present work deals with the modification of lignocellulosic residues to obtain low cost adsorbents for diminishing an oil-products spill in seawater. The adsorbent (barley straw) was pretreated by autohydrolysis, without using any catalyst or organic solvent, in a PARR autoclave at 160-240 oC for 0-50 min. The water and oil adsorbency (defined as the ratio of water or oil adsorbed to dry adsorbent weight) test was performed, using diesel and crude oil of predetermined quality specifications. Water, diesel and crude oil adsorbency-values were found to increase by increasing the autohydrolysis time for reaction-ending temperatures 160 and 180 oC. At 200 oC, these adsorbency-values were increasing for autohydrolysis time less than 30-35 min and then were decreasing. Moreover, these values were found to decrease at 240 oC.
