Ni-Co Bimetallic Catalyst Synthesis by Co-impregnation Method for Hydrogen Rich Gas Production from Olive Pomace

Abstract

Hydrogen is defined as an ideal energy carrier among sustainable, clean and renewable energy sources, so it is important to produce hydrogen and to develop the sustainable hydrogen economy. Catalyst plays a vital role in the production of hydrogen at low cost and high efficiency. Selection of support and active material, catalyst preparation methods considerably affect the activity of the catalysts. In this work, Ni-Co bimetallic based catalysts were synthesized by the co-impregnation method using different support materials (Al 2 O 3 , ZrO 2 , ZnO, Al 2 O 3-ZrO 2) in order to obtain the highest hydrogen-rich gas from biomass. Ni-Co bimetallic catalysts were synthesized and characterized by XRD, XRF, TGA, SEM and FT-IR techniques. The activities of Ni-Co/Al 2 O 3 , Ni-Co/Al 2 O 3-ZrO 2 catalyst were studied in gasification of olive pomace. It was found that the H 2 yield of the Ni-Co/Al 2 O 3 (10.76 mole H 2 /kg Olive pomace) was higher than Ni-Co/Al 2 O 3-ZrO 2 (5.37 mole H 2 /kg Olive pomace).
