| Abstract | The crop straws are abundant recycled ligno-cellulosic resources. Preparing wheat straw microcrystalline cellulose using the cellulose decompounded from crop straws is a kind of efficient utilization of ligno-cellulosic resources. The preparation and desiliconization process of wheat straw microcrystalline cellulose were studied in this paper. The results showed that the optimal hydrolysis process parameters were as follow: hydrochloric acid concentration 2 moll -1, hydrolysis temperature 70 °C, hydrolysis time 90 min, and solid-liquid ratio 1:15. After alkali treatment, the ash content of microcrystalline cellulose decreased substantially. Thevoptimal process conditions were: alkali dosage 15%, temperature 80 °C, microcrystalline cellulose concentration 10%, treatment time 30 min. The ash content of microcrystalline cellulose was decreased by 84.39%. SEM-EDS results showed that SiO 2 could be dissolved and decreased after alkali treatment in the wheat straw microcrystalline cellulose. © 2011 American Scientific Publishers. | ||||||
