Abstract: Embodiments disclosed herein relate to a modified reactor system for creating coated particles of thermostable agents having reduced loss and improved coating uniformity due to avoidance of adherence of the particles to the reactor or to other particles. In certain embodiments, a reactor system includes a reactor vessel configured to receive particles of thermostable agents, and one or more agitating appendages or devices, including at least one of ultrasonic agitator, mechanical impactor, and low-frequency vibrator either directly connected or in fluid communication with the reactor system for sonicating, impacting, or vibrating a reactor vessel during the particle coating process. In some embodiments, the reactor system includes a gas phase dosing system configured to introduce alternating pulses of chemically gas phase materials into the reactor vessel to form a coating on the particles while continuously or intermittently agitating the reactor system.

Abstract: A method of making a supported gas separation molecular sieve membrane. In this method a porous support, which is preferably pretreated, is contacted with a molecular sieve synthesis mixture under hydrothermal synthesis conditions. The contacting step is conducted for a shortened crystallization time period. The resulting coated porous support is calcined to yield the supported gas separation molecular sieve membrane having particularly good gas separation characteristics.
