The goal of this project is to develop novel catalytic pyrolysis technology for the production of stable biofuels with high energy content.
1) A catalyst for upgrading of pyrolysis oil
Hydrodeoxygenation (HDO) is one of the most important reactions to improve quality of bio-oil. HDO of guaiacol as a model compound of lignin derivative was examined by using a variety of nickel phosphide catalysts with different P/Ni ratios. With increase of P/Ni ratio, HDO activity drastically increased. Benzene and cyclohexane were obtained as final products over Ni2P/SiO2 catalyst at 300 oC under an atmospheric pressure of hydrogen. Effect of support on the HDO reactivity has also been examined. Although acidic supports such as silica-alumina and ZSM-5 zeolites are expected to be effective for cracking, HDO activities of Ni2P catalysts supported on these acidic supports were much lower than that of Ni2P/SiO2. Main products of guaiacol HDO were benzene, phenol, and catechol for Ni2P/SiO2, silica-alumina and ZSM5, respectively.
2) Lab-scale production of biooil by catalytic fast pyrolysis and biooil analysis
The produced bio-oils from woody biomass (cedar chips) by a lab-scale catalytic fast-pyrolysis reactor with/without up-grading, i.e. HDO reaction over Ni2P catalyst, were analyzed by means of several techniques such as CHNS elemental analyzer, GC-MS, NMR, IR and ESI FT-ICR MS spectroscopy. These data indicated that the HDO treatment over Ni2P catalyst drastically decreased the amount of oxygen in the bio-oil, mostly in the range of O8-O11 compounds, and improved viscous property and homogeneity.
3) Process analysis
Hydrogen production in the two-stage circulating fluidized bed process was proposed with a partial combustion of char and a subsequent water gas shift reaction. With the hydrogen production process, overall energy conversion increased by about 10 %. It was revealed that almost all of the hydrogen needed in the hyrodeoxygenetaion could be produced at the pyrolysis temperature of 723 K.
4) A fluidized bed reactor for catalytic fast pyrolysis
Meiwa industry Co., Ltd. connected bio oil production system by fast pyrolysis and catalytic reforming system with the circulation fluidized bed which they demonstrated until last year, and examined as two steps of fluidized bed. As a result that we connected each line, and constructed two steps of fluidized bed, we were able to produce bio oil by production system for fast pyrolysis. On the other hand, it was necessary to perform correspondence of non-enforcement, but we carried out measures while repeating driving, and became able to evaluate the application with the catalyst carrier in parallel.
