Microwave-assisted adsorptive desulfurization of model diesel fuel using synthesized microporous rare earth metal-doped zeolite Y

الملخص EN

The microwave-assisted adsorptive desulfurization of model fuel (thiophene in n-heptane) was investigated using a synthesized rare earth metal-doped zeolite Y (RE Y).

Crystallinity of the synthesized zeolite was 89.

5 %, the silicon/aluminium (Si/Al) molar ratio was 5.

2, the Brunauer–Emmett–Teller (BET) surface area was 980.

9 m2 / g, and the pore volume and diameter was 0.

3494 cm3 / g and 1.

425 nm, respectively.

The results showed that the microwave reactor could be used to enhance the adsorptive desulfurization process with best efficiency of 75 % at reaction conditions of 100 °C and 15 minutes.

The high desulfurization effect was likely due to the higher efficiency impact of microwave energy in the interaction between sulfur in thiophene and HO-La(OSiAl).
