Effect of promoters (Mn, Zn and ZrO2) on the characterization of SBA-15 supported cobalt catalyst for fischer-tropsch synthesis

TL;DRAbstract

Fischer–Tropsch synthesis (FTS) is a part of gas-to-liquids (GTL) technology,which produces synthetic liquid hydrocarbons from natural gas.Recently the production of clean fuels and particularly of synthetic diesel by means of the FTS process has aroused renewed interest in both industrial and academic field.This process was shown to be catalyzed by certain transition metals,such as Co which present the highest activity.This research work is about the synthesis of SBA-15 and preparation of catalyst with different promoter Zr, Zn, Mn – Co based supported by SBA-15 by wet impregnation catalysts and characterizes all sampling.All materials were characterized by several physico-chemical techniques such as TGA,SEM and FTIR.The catalytic and characterization results show a great influence of mesoporous support porosity on the structure, reducibility and FTS catalytic behavior of cobalt oxide species supported over these ordered materials.After modification of SBA-15 by Co with different load
