Microwave assisted catalytic pyrolysis of bagasse to produce hydrogen

Using Ni/SiC as a catalyst, bagasse was microwave-assisted pyrolysis in a homemade quartz reactor. The results showed that with the continuous increase of Ni content, the experimental catalytic pyrolysis effect on bio-oil became more and more obvious, and the hydrogen yield gradually increased. When Ni content exceeded 8%, the hydrogen yield and bio-oil catalytic pyrolysis efficiency decreased, and the lowest bio-oil yield was 9.55% when Ni content was 15%, With the increase of power, the catalytic cracking efficiency and hydrogen yield of bio-oil increased, With the increase of catalyst dosage, the catalytic efficiency and the hydrogen yield increase gradually. When the catalyst quality exceeds 1/4 of the material, the growth rate of catalytic efficiency decreases, after alkali treatment, the variation law of hydrogen yield and bio-oil is consistent with that without alkali treatment. In contrast, more hydrogen can be produced after alkali treatment. Under the optimum conditions, the hydrogen yield was 35.85 g/kg biomass.
