Carbon Recycling

We contribute to the improvement and expansion of carbon recycling technology through measurement and analysis technologies from processes to materials, including gas monitoring technology for CO2 and other gases, and analysis of catalyst materials for the production of chemicals and synthetic fuels.

Carbon recycling is a technology that effectively turns CO2 and waste plastics into chemicals, fuels, various materials and thermal energy.  

One of the typical applications is methanation that uses renewable energy to synthesize methane (CH4) by reacting CO2 with hydrogen obtained from water. Another is the artificial photosynthesis that synthesizes chemicals using CO2 as raw material to convert water and CO2 into hydrogen and organic compounds, using solar energy like plants.

Synthetic Fuels and Methanation

Synthetic fuels are made by synthesizing CO2 and hydrogen, and those which are made with green hydrogen (CO2-free hydrogen derived from renewable energy) are called "e-fuel".   

Additionally, methanation technology is expected to be put into practical use. It synthesizes methane (CH4) through a chemical reaction of hydrogen and CO2 after electrolyzing water into hydrogen and oxygen using electricity derived from renewable energy, or synthesizes methane from synthesis gas (mixed gas of hydrogen and CO) obtained from the co-electrolysis of water and CO2. Methane can be used as a raw material for Liquefied Natural Gas (LNG) for city gas and methanol, and those which is produced in this way is also called "synthetic methane" or "carbon neutral methane". 

Gas Concentration Monitoring

In the methanation processes, it is required to measure and monitor the concentrations of highly-purified hydrogen and CO2 as the raw materials for methanation, as well as synthesized methane gas.

Co-electrolysis Evaluation

Major methanation technologies include " Sabatier reaction technology," in which hydrogen produced by electrolyzing water reacts with CO2 in a Sabatier reactor to produce methane, and " co-electrolysis technology," in which water and CO2 are simultaneously electrolyzed to produce hydrogen and CO and are subsequently used to produce methane in a methanation reactor.
Compared to the Sabatier reaction technology, the co-electrolysis technology is superior in terms of energy conversion efficiency because it generates less heat loss from the waste heat generated during the reaction.

CO2-derived Chemical Production and Artificial Photosynthesis

Technologies that use CO2 as a raw material to produce chemicals and storable energy (hydrogen, methanol, methane, etc.) through chemical reactions are also an important element of carbon recycling. Among these, artificial photosynthesis is a technology that uses solar energy to synthesize chemicals such as olefins from water and CO2. It is called "artificial photosynthesis" because it resembles the mechanism by which plants carry out photosynthesis from sunlight and CO2. R&D for more efficient photocatalysts is underway with the aim of achieving a decarbonized society.

Characterization of Photocatalysts for Artificial Photosynthesis

To effectively utilize sunlight, it is necessary to excite complex catalysts to long wavelength areas such as the near-infrared area. The excited state of the complex catalyst is correlated with fluorescence spectroscopy.

Fluorescence and Absorbance Spectrometer Duetta can evaluate luminescence properties in the near-infrared area, such as above 1,000 nm, and contributes to the improvement of reaction efficiency of catalyst materials.

Absorption and Fixation in Concrete Materials

CO2 emissions in concrete production (especially cement production) can be reduced in total by combining "CO2 fixation", which is the absorption and fixation of CO2 in concrete, with the use of industrial by-products.

The carbon and sulfur analyzer EMIA-Step can measure the amount of carbon while raising the temperature, which enables to measure the change in the amount of CO2 adsorbed on concrete and other materials depending on temperature.

Chemical Recycling (Disassembly and Reuse as Chemicals and Raw Materials)

RPF (Refuse Paper & Plastic Fuel) is a solidified fuel made mainly from used paper and waste plastic.

Screening analysis of chlorine concentration in RPF

RPF may contain chlorine (CI), which is one of the causes of incinerator degradation, and checking for CI before using RPF as fuel for incinerators can help prevent incinerator degradation.

Thermal Recycling (Incinerated and Reused as Heat)

Gas and dust measurement plays an important role in the optimal operation of incineration plants and power generation facilities that use waste plastics and RPF as fuel, as well as in high-efficiency power generation. We continue developing solutions with new measurement methods and analyzers.
