abstract

mfi-type zeolite membranes (zsm-5) were prepared on α-alumina tubular supports and tested for separation of h2/co mixtures. the effect of pressure and temperature on h2 and co flows and selectivity was investigated. the best results in this work were obtained with a zsm-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with microwave technique. in this case the h2 permeance was obtained 2.8 × 10-6 mol/ (m2.s.pa) with a h2/co ideal selectivity of 4.9 at 373 k. the permeation results of four gas (h2, co, n2, ch4) on the synthesized membrane were also investigated.

Microwave-assisted Synthesis of MgFe2O4-ZnO Nanocomposite and Its Photo-catalyst Investigation in Methyl Orange Degradation

In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...
