Catalytic Pyrolysis of the Alga Saccharaina Japonica using Co/γ-Al2O3 Catalyst |
| 초록 |
Saccharaina Japonica (S. Japonica) has the potential to be the source of liquid fuel. The main component in the bio-oil, dianhydromannitol (DHM), can be obtained by fast non-catalytic pyrolysis. However, when investigating over Co and Ni catalyst supported on γ-Al2O3 in the micro tubing reactor with various loading amount of catalysts from 2 wt.% to 8 wt.% at temperature range of 360-400˚C, the amount increased more. Compared with Ni/γ-Al2O3 catalyst, Co/γ-Al2O3 catalyst significantly affected pyrolysis of S. japonica, showing the increase of bio-oil yield. Applying over 2 wt.% catalyst loading and operating at higher pyrolysis temperature reduced the catalytic activity possibly due to the increased viscosity that limited the diffusion of three-phase reaction. Nevertheless, the 40.7 wt.% bio-oil yield from the pyrolysis of S. Japonica at 380˚C and 5 min of residence time was higher than that attempted in the past with maximum yield of 28.78 wt.%. |
