Abstract
Mordenite, a synthetic zeolite, is produced by reaction of particulate volcanic glasses with limited amounts of strongly basic aqueous solutions at elevated temperature and autogenic pressure for approximately one day.
Claims9
A method for the production of mordenite and mordenite aggregates from volcanic glass according to the following steps:
- (a) preparing a mixture of particulate volcanic glass and an aqueous strong base solution in a ratio of from about 2:1 to about 10:1 parts glass per part aqueous base solution;
- (b) maintaining said mixture at a temperature of from 96.degree. C. to 200.degree. C. and autogenic pressure in a sealed vessel for from about 12 hours to about two weeks;
- (c) recovering mordenite as a product.
