| Abstract: | The conversion of bio-oxygenates into hydrogen (H2) via catalytic steam reforming is a green approach for H2 generation. In the present work, butanol was chosen as renewable feedstock for producing H2. Two catalysts supported on multiwalled carbon nanotubes, Ni/CNT and Co/CNT, were synthesized by the wetness impregnation method and used for butanol reforming. Trials were performed in a fixed-bed reactor in the 623–773 K range using S/C ratio equal to 33.3 mol/mol (here, S/C denotes steam to carbon ratio). The Ni/CNT catalyst exhibited higher reforming activity. The best catalytic performance for Ni/CNT was observed at T = 773 K. At this temperature, high values of butanol conversion (87.3%) and H2 yield (0.75 mol/mol) were observed at W/FA0 = 16.7 g h/mol (here, W is the catalyst mass and FA0 is the molar flow rate of butanol at the inlet). The performance of Ni/CNT catalyst for steam reforming of synthetic bio-butanol was also investigated at T = 773 K and H2 yield of 0.65 mol/mol was achieved. |
