1 day ago When the zeolite is in the non-packed reactor, it is filled in the reactor container. However, the bulk density of zeolite particles (particles diameter 35 mm) in the non-packed reactor is larger, which leads to higher pressure drop in the reactor and insufficient contact between air and zeolite.
