%X Mesoporous silica (SBA-15) was prepared using P123, hydrochloric acid (HCl) and tetraethyl orthosilicate (TEOS). Hybrid catalysts comprising Cu/ZnO/Fe/K/Rh and Cu/Al/Fe/K/Rh on SBA-15 support were prepared by a wet impregnation method. The morphology and surface area of catalysts were characterized by using field emission scanning electron microscopy (FESEM) and Brunauer-Emmet-Teller (BET) techniques, respectively. These catalysts were evaluated in a microactivity fixed-bed reactor for CO 2 conversion at 3 MPa, 523.15 K and gas flow rate of 48 ml/min. The Cu/ZnO/Fe/K/Rh and Cu/Al/Fe/K/Rh hybrid catalysts were tested at two different GHSV. The lower GHSV of 5760 ml/g.hr exhibited higher CO 2 conversion of 6.21 and 6.92 as compared to those of higher GHSV of 14,400 ml/g.hr with 1.21 and 2.22 CO 2 conversion. © Published under licence by IOP Publishing Ltd.
