Abstract
Process for forming a zeolite particle in the fluidizable size range from 20 to 150 micrometers. Acid-stable, molecular sieve zeolite mordenite is formed by mixing silica-alumina gel particles in the fluidized size range with sodium silicate, sodium hydroxide, sodium chloride, and mordenite seed crystals. For example, the mixture is reacted under autogenous pressure at 180.degree. C for 24 hours.
