A zeolite or zeolite-type material is in fine powder form when it is synthesized or modified. Zeolites are applied in several processes, such as cracking, separation, purification, isomerization, hydrocarbon synthesis, synfuel production, refining and production of chemicals. Usually, fixed-bed or fluidized-bed reactor technologies are involved in these processes. Although as-synthesized zeolites are obtained in the form of a fine powder it might have not been used directly in such kinds of reactor technology. In addition, in cases where the process requires a fixed-bed reactor technology, the problem relies on the fact that powder causes very high pressure drops through the reactor and exhibits poor mechanical strength that can lead to damage or degradation of the catalyst, thus creating fines at the reactor outlet. Indeed, the presence of small particulates can lead to dramatic consequences on both the reaction and the equipment.
