Experiment equipment 試験装置

Bubbling fluidized bed reactor
A bubbling fluidized bed reactor with a 2-meter-high reaction tube has been newly installed. By supplying air or reactive gas from the bottom, the particle bed is fluidized to create a uniform reaction environment.
Drop tube furnace(DTF)
The DTF simulates spray combustion under conditions similar to commercial boiler. In our lab, is used to evaluate ash deposition and combustion characteristics.
Batch-type, vertical furnace
It is equipped with a vertically movable electric furnace which allow for rapid heating of samples to simulate isothermal combustion and gasification processes.
TG-DTA
The use of a horizontal differential system minimizes the effect of gas flow, allowing for simultaneous differential thermal and thermogravimetric measurements.
Thermomechanical analyzer(TMA)
It is capable of detecting shrinkage displacement under load during heating process.
SOFC evaluation test equipment
A button-shaped solid oxide fuel cell is placed in the ceramic holder and utilized for performance evaluation under biomass gasification gas conditions.
NOx reduction equipment
A novel NOx reduction device featuring a calcium ferrite-based catalyst and capable of continuous biomass char feeding is currently under development. Stay tuned!

Analytical equipment 分析装置

Scanning electron microscope (SEM)
The nanostructure of the sample is observed at the nanometer scale. Coupled with EDX, qualitative and quantitative element analysis is also possible.
Elemental analyzer
It performs elemental analysis (C,H,N,S) of organic compounds using the combustion method. It is extensively applied in various materials, including coal, biomass, and waste.
Micro gas chromatography (Micro-GC)
It is used for analyzing exhaust gas composition. A variety of models are available in our lab to accommodate different types of exhaust gases.
Contact angle mesurement equipment
This device measures the wettability between substrate and sample. Equipped with a CCD camera, it enables quantitative evaluation of time-dependent changes in the contact angle.
Surface area and porosimetry analyzer
This device measures specific surface area and pore size distribution using the volumetric method based on gas adsorption.
X-ray fluorescence spectrometer (XRF)
Without any pretreatment, solid samples can be directly analyzed for trace elements in a non-destructive way.
ICP-OES
High-sensitivity measurements at the ppm to ppb level enable precise analysis of metallic and semi-metallic elements in liquid samples.
