Renewable Synthetic Fuel
To reduce drastically the emission of CO2 in the transportation and aircrafts sectors, we are researching technology to produce renewable fuels that can replace conventional fossil fuels such as gasoline, jet fuels and gas oil using hydrogen derived from renewable energy and carbon dioxide as feedstocks. The carbon dioxide used as a feedstock is collected from factory exhaust or the atmosphere. This is the reason why the use of renewable fuel does not increase the concentration of CO2 on the earth. Since the composition of renewable fuels is very close to that of crude oil, conventional refineries can treat them and existing aircrafts and automobiles that use fossil fuels can be used without any modification. Once the manufacturing technology is established, we think that this technology will spread very quickly because the distribution channels for fuels are already established.
Various technological innovations such as manufacturing processes and catalysts are necessary to improve this technology.
For technological innovations, we are working on research on catalysts that can efficiently produce fuels and development of processes that maximize the performance of catalysts.
Development of Catalysts for Efficient Fuel Production
It is important to convert feedstocks, hydrogen and carbon dioxide, into fuels without any wastes. When hydrogen and carbon dioxide are reacted, not only light oil that is used as fuel, but also gas such as methane and heavy oil such as wax are produced. It is necessary to develop a catalyst that can produce more light oil in order to obtain only fuels more efficiently.
Process Development that Maximizes the Catalyst Performance
It is important to use heats effectively in each manufacturing process. Some processes produce heats while others require those, so it is necessary to combine each process correctly.
We are also considering how to reduce the carbon dioxide emitted from the manufacturing process.
We hope to establish the production technology of renewable fuels that are friendly to the global environment in the near future.
