Abstract

Bentonite, a new class of layered compounds, displayed a broad application prospects in catalyst supports. The influencing factors of sodium modification on bentonite were studied in this paper. The bentonite obtained the best charater after the 10% bentonite slurry was treated by 3% Na2CO3 at 60ºC for 1.5h. It can be seen that the swellvalue increased from 19.7 ml/g to 86.2 ml/g, the blue absorption power from 28.8 g/100g to 43.6 g/100g and the cationic exchange capacity from 0.384 mmol/g to 1.026 mmol/g. The X-ray Diffraction showed the interlayer space changed from 1.4321 nm to 1.229 nm. All the results meant that the Ca-bentonite had been modified into Na-bentonite and obtained good expansibility and dispersibility.
