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 acid hydrolysis, using sulfuric acid 0.045 N as a catalyst, in a PARR autoclave at 160-220 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 oil and crude oil adsorbency were found to increase by increasing the acid hydrolysis time for reaction-ending temperatures 160 and 200 oC and to decrease at 220 oC.
