In our laboratory, we conduct research on High-efficiency energy/material conversion of carbon resources such as biomass conversion,
separation/recovery and effective use of CO2 based on reaction and separation engineering. Currently, we are a team of 28 people
including 8 staff (Professor: Koyo Norinaga, Research Associate Professor: Hiroshi Machida, 7 Project Associate Professors, 1
Postdoctoral Researcher and 4 secretaries) and 21 students 7 PhD students, 10 MS students, 3 Undergraduate students and 1 Researchstudent). In addition to being in charge of education in the Departments of Materials Engineering and Chemical Systems Engineering, weserve as the Future Society Creation Organization, which was established to promote industrial collaboration, and are also involved in theplanning and management of various (on-campus/Intercampus research/international/industry-academia) collaboration projects.

ENERGY-SAVING CO2 SEPARATION AND RECOVERYMETHANATION

CO2 separation and recovery by the chemical absorption method using anWe believe that the so-called Power to Fuel, which is derived from renewableamine solution has been industrialized, but it is an energy-intensive
process.Our laboratory found an amine-ether mixed aqueous solution thatenergy or contains methanation derived from CO2-free hydrogen and CO2, will
become more critical in the era of mass introduction of solar and wind power.

separates the liquid-liquid phase into a concentrated CO2 phase and a dilutephase during the CO2 capturing process. This promotes CO2 absorption andregeneration and significantly reduces the energy required for separation and

There has been no large-scale demonstration of the methanation process sofar. We want to contribute to the speeding up of scale-up by using reaction raterecovery. Aiming for further energy saving, we are also working on elucidationof CO2 absorption/regeneration mechanism using in-situ spectroscopic
analysis and new absorbent solution development by molecular simulation.
Besides, we propose a "CO2 separation/recovery/utilization integrated
process" that simulates CO2 regeneration using hydrogen as a stripping gas
and utilizes the obtained CO2/hydrogen mixed gas as a direct raw material forCO2 conversion processes such as methanation and methanol synthesis. We
also carry out continuous tests and energy evaluations using laboratory plants
to develop various technologies for practical use in collaboration with machine
manufacturers.

COKE FOR IRON MAKING
The resource amount of coking coal that forms lump coke is limited, and it isessential to develop a technology for producing coke to make iron from
inexpensive coal materials. We are collaborated with blast furnace
manufacturers to develop a technology for producing high-grade coke from lowgrade raw materials by interpreting the dry distillation/carbonization reaction
mechanism of solid carbon fuel and new reaction operations.

CERAMIC-COMPOSITE
Engines equipped with ceramic composites (CMC) on the stationary blades andthe moving blades directly downstream of the burner are being implemented inconsumer aircraft. Mass production technology with price competitiveness andquality control is indispensable for the general-purpose commercialization ofCMC. We want to contribute to developing mass-production technology for Sicbased composite materials through numerical simulation. Regarding theproduction of CMC by the chemical vapor-phase infiltration method, we areworking with the manufacturer to develop a unique simulation technology thatconsiders the non-stationarity associated with chemical reactions, masstransfer, and impregnation.

modeling and computational fluid dynamics. To design a catalyst-fixed bed
reactor for Methanation (Exothermic Process) that realizes the optimum
temperature distribution, we have developed a methanation reactor numericalanalysis code that considers the reaction, heat transfer and flow on an opensource basis.We are working with catalyst and plant manufacturers, resource
development companies, and national research institutes to commercialize theprocess.

THERMOCHEMICAL CONVERSION OF SOLID CARBONRESOURCES
Combined cycle power generation via solid carbon resource gasification
enables highly efficient power generation compared to a combustion boiler
power generation.We aim to improve the gasification efficiency by modeling thechemical reactions in the gasification furnace at the molecular and radicallevels, predicting the reaction characteristics of tar, soot, sulfur, and nitrogencontaining compounds. We are also promoting collaboration with top-classresearchers in Japan and abroad. We want to visualize the inside of a furnaceand predict gasification characteristics by calculating the detailed chemical
reaction model's integrated analysis, heat transfer in the furnace, and fluid
calculation.
