PROCESS FOR THE PREPARATION OF AN IMPROVED CHABAZITE FOR THE PURIFICATION OF BULK GASES

摘要

PATENT 211PUS03871 A process is provided for preparing a synthetic chabazite having a Si/Al ratio of 1.8 to 2.3 by mixing an alumina source, sodium hydroxide, potassium hydroxide, a TMA reagent at a ratio of (TMA)2O:Al2O3 of 0.08 to 0.0001, and a silica source to form a gel, crystallizing the gel by heating at a temperature of from about 25.degree. to 150.degree. C for at least one hour, and separating the resulting chabazite product.
