Book "Carbon Cycle (Carbon Recycling) Technology from the Perspective of Catalysts 2021"

To effectively promote CO2 reduction, it is essential to develop catalytic processes that are not limited to laboratory-level reactions but can operate stably over the long term and be industrialized. The synthesis technologies for fuels, chemicals, and polymers using hydrogen derived from renewable energy and CO2 are crucial technologies for breaking away from dependence on fossil resources, and research, development, and implementation are accelerating globally. In the fuel sector, e-methanol and e-fuels synthesized from CO2 and hydrogen are gaining attention as decarbonization measures in the shipping and aviation industries, and the development of highly active and durable methanol synthesis catalysts and compact FT synthesis processes is underway. In the chemical sector, advancements are being made in reaction pathways, such as the reverse shift reaction that converts CO2 to carbon monoxide and the direct conversion to oxygen-containing compounds with two or more carbon atoms. Furthermore, in the polymer sector, the practical application of polycarbonate and polyurethane derived from CO2 is progressing, with molecular weight control and property enhancement through catalyst design becoming competitive factors. This overview aims to organize and introduce these technological trends from the perspective of industrial catalysts, hoping to contribute to the social implementation of future CO2 utilization technologies.
