PREPARATION OF SMECTITE BASED SORPTION AGENT FOR ABSORBING LIQUID

摘要

PURPOSE: To provide a process for production of a sorbent based on smectite for uptake of liquid. CONSTITUTION: A smectite with a water uptake capacity of less than 115% (in terms of the dried smectite with a residual water content of 6 wt.%) and a smectite content of around 40-65 wt.%, and/or, a two-layer silicate is/are mixed with an alkaline smectite and homogenized by intensive shearing. The mixture is gently dried and the dried mixture is fragmented.
