RESEARCH TOPICS (Last update May 2020)


Modern civilization largely depends on energy of fossil fuels.In Japan, we use ~0.66 t of natural gas, ~1.5 kL of oil, and ~1.5 t of coal per year per capita in 2016, resulting in the CO2 emission of ~9.0 t per year (i.e. ~14000 L per day) per capita. Considering resource depletion and climate change, increase in utilization of renewable energy and value addition of carbonaceous resource utilization are strongly required. In our group, we have conducted the following research topics:

Topic 1: Process development for biochemicals and biofuels production

Topic 2: Development of reactors for thermochemical conversion of carbonaceous resources (pyrolysis, gasification, liquefaction, and esterification)

Topic 3: Reaction kinetics and hydrodynamics of fluidized beds

Topic 4: Development of value added thermal and biomass power plants
Research Topics
Process development for biochemicals and biofuels production
 Biorefineries have gained much attention. We have developed total system for biochemical and biofuels production from woody, algal and waste biomass so that we can greatly reduce total CO2 emission and cost. We also design and evaluate energy-efficient and economically feasible drying process that is required for biomass utilization.
Development of reactors for thermochemical conversion of carbonaceous resources (pyrolysis, gasification, liquefaction, and esterification
 We have developed novel reactors for thermochemical conversion of coal and woody/algal biomass. We have also studied efficient bio-oil production process with nutrients recovery from biomass, which is essential for future sustainable large-scale biomass utilization system.
Reaction kinetics and hydrodynamics of fluidized beds Fluidization technology is widely used for continuous particle processing in industry. We have designed and developed conventional fluidized bed reactors and a novel downer pyrolyzer, and analyzed hydrodynamic behaviors and reaction kinetics of various fluidized beds.
Development of value added thermal and biomass power plants

 To greatly reduce CO2 emission from power generation sector, we study further improvement of thermal efficiency of thermal and biomass power plants. We also try to add new values of these plants during non-steady state operation by combining variable renewable energy for stable operation of the future power grid systems.
