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

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 utilizatio |
