RESEARCH TOPICS (Last update August 2025)


In Japan, we use ~0.62 t of natural gas, ~1.1 kL of oil, and ~1.4 t of coal per year per capita, resulting in the CO2 emission of ~8.3 t per year (i.e., ~13000 L per day) per capita (as of 2020). Considering resource depletion and climate change, great 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:

Research Keywords:
Biomass Conversion Engineering
Thermochemical Reactions of Carbonaceous Resources (Pyrolysis, Gasification, Combustion/ Liquefaction, Esterification, Hydrogenation etc.)
Fluidization丒Fluidized Bed Engineering
Process Design and Development (Green Chemistry, Technoeconomic Analysis (TEA), Environmental Impact analysis)
Power Generation Process (Thermal power generation , biomass power generation, heat storage and power generation etc.)
Research Topics
Development of greener processes for production of fundamental chemicals (levulinic acid, succinic acid, and the related substances) and fuels from woody biomass
 Biorefineries have been attracting attention. In our group, we have developed highly feasible processes to produce fundamental useful chemicals (levulinic acid, succinic acid and their derivative) from woody biomass. We design processes from the perspectives of Green Chemistry and waste reduction, evaluating both economic viability and environmental impact.
In conjunction with the aforementioned process development, we conduct reaction experiments using small-scale reaction vessels to investigate the in products, elucidate reaction mechanisms, and determine reaction rate constants.
Process development and experiments for producing useful chemicals and fuels from microalgae
 We conduct hydrothermal liquefaction reaction by using a continuous or a small-scale autoclave reactor, and the related separation experiment with the aim of improving the economic/environmental efficiency of useful chemical production from algae. Based on the results, we also develop and evaluate highly feasible processes.
Development of high value-added power plants integrated with renewable energy and fluidized bed heat storage systems
 To mitigate the intermittence and fluctuation of variable renewable energy and waste heat, we try to add new values of the thermal, biomass and geothermal power plants during non-steady state operation by integrating with heat storage systems.
We have developed fluidized bed heat storage systems, and analyzed hydrodynamic behaviors, the temperature change and heat transfer rate by using special heat storage materials.
