Nanoadsorbents from MIL-101(Cr) metal-organic framework were prepared via hydrothermal method with different additives (hydrofluoric acid, sodium acetate, acetic acid, expanded graphite and without additive) under different synthesis conditions. The samples were characterized by XRD, SEM and nitrogen sorption at 77 K. The frameworks were used for dehydration of liquid fuel DMAZ containing 3 wt% water, for several consecutive cycles between adsorption (at ambient temperature and atmospheric pressure) and desorption at 343 K. Water stability and recyclability of the frameworks were almost similar but the MIL-101 using acetic acid attribute to the higher pore volume and surface area, with had the most capacity for water capture. Also, adsorption capacity of MIL-101 was compared with commercial zeolite adsorbents (3A and 4A) for dehydration of aforementioned solution. The uptake capacity of MIL-101 with was 7-8.5 times higher than commercial 3A and 4A zeolites with 0.18 and respectively. MIL-101 was almost fully dehydrated at 343 K, in contrast to conventional porous zeolites requiring high temperature dehydration (573 K). MIL-101 was shaped and used in an adsorption column with capacity. Shaped MIL-101 showed robust cyclic performance in the dehydration tests.
