Beschreibung
Zusammenfassung:	FIELD: chemical industry; production of sorbents obtained from cellulose-containing materials and used for cleaning various surfaces from petroleum products. ^ SUBSTANCE: cellulose-containing material is subjected to extrusion at simultaneous auto-hydrolysis at temperature not below 100°C and pressure no less than 10 Mpa at mechanical shear-compressive strain. ^ EFFECT: reduction of time required for performing the process; reduced power requirements. ^ 5 cl, 5 ex
