Hydrogen production from steam reforming of bio-oil and acetic acid using ni/γ-al2o3 catalyst was studied in a laboratory-scale fixed bed *** study selected different ni loadings(16.8%and 30.5%)in ni/γ-al2o3 catalysts and reaction temperatures(500°C,600°C and 700°C)as variables to optimize the hydrogen yield and selectivity of gases *** were carried out in an isothermal *** catalysts were prepared on wet impregnation of aγ-al2o3 which supported with two different ni *** principal gases generated were H2,Co,Co2 and *** results from steam reforming of acetic acid showed that the yield and selectivity of hydrogen using the catalyst with 30.5%ni were significantly higher than that with 16.8%*** results showed that the most favorable temperature for hydrogen production was 600°C,and the steam reforming of bio-oil using ni/γ-al2o3 catalyst with 30.5%ni showed that the yields and selectivity of H2 and Co2 increased with the temperature increasing while CH4 and Co selectivity *** results showed that the most favorable temperature for hydrogen production from bio-oil using 30.5%ni/γ-al2o3 was 600°C,at which hydrogen yield was at its maximum of 65%.
