Summary:The primary objective of the present work was to investigate the effect of fluid movement on synthesized chromium-benzenedicarboxylate, MIL-101(Cr), quality through a set of experiments performed in a circulating tube reactor using an interval schedule, i.e., circulation stopped periodically. The results revealed that using 30 s pump-ON period resulted in cubic crystals while setting this parameter on 90 s created an agglomerated structure. In the optimum condition, the synthesized MIL-101(Cr) had the BET surface area 2354 m 2 /g, pore volume 1.94 cm 3 /g, and CO 2 adsorption capacity 10.9 mmol/g. Using microwave irradiation to activate the produced crystals improved crystal BET surface area to 3860 m 2 /g.
