Development of Estimation Model for Supply-Demand Balance of Biomass Resources in Zhejiang Province, China

Report on the 5th Conference on Biomass Science ( The Japan Institute of Energy )  5   176 - 177   2010.01

　View Summary

The material flow accounting model was developed to calculate a supply-demand balance at a province level in China, and was applied to Zhejiang Province. We also evaluated the effect of reductions in GHG emissions, mineral resources consumption, and land use through the following two alternative options of biomass utilization; Energy conversion and material recovery. The results showed that GHG emissions reduction effects by energy conversion case could be 30Mt-CO_2 and 1.8 times bigger than material recovery case. Yet, the latter could save more mineral resources and land.

P-124 Hydrodenitrogenation of Bio-Oil Produced from Activated Sludge

IZHAR Shamsul, YOSHIDA Noboru, YAMAMOTO Yugo, MORIOKA Toru, NAGAI Masatoshi

Proceedings of the Conference on Biomass Science ( The Japan Institute of Energy )  5 ( 0 ) 100 - 101   2010

　View Summary

The hydrodenitrogenation of the bio-oil produced from activated sludge was performed at 250-370℃ and 2.0MPa over the sulfided P-added NiMo/Al_2O_3 catalysts. The bio-oil was prepared from the pyrolysis of dried activated sludge using steam, nitrogen and air fed to a fluidized bed reactor at 500℃ and residence time of 1s. The reaction in the present work was carried out in a continuous flow fixed bed reactor with LHSV=5-10h^<-1>. The xylene-soluble (partially dissolved) bio-oil (BO/Xy) and totally soluble bio-oil in ethanol (BO/EtOH, ratio=1:4) and in diethylene glycol (BO/DEG, ratio=1:8) were prepared as the reaction feed. The nitrogen containing compounds were totally denitrogenated throughout the 6h reaction period during the hydrotreatment of BO/Xy containing 0.5% nitrogen compounds at 367℃. Indole, pyridine and other compounds were denitrogenated.
