Exploration of the CO2 conversion under China’s carbon neutrality goal

Abstract

To guide the development of CCUS by government policies, it is necessary to redefine the attributes and value of carbon dioxide, and to deeply explore its resource attributes. In the energy revolution, all social activities and industries will be affected and reconstructed in order to enable the transformation from carbon-based energy to carbon-free energy. Thinking of CCUS green technology in the low carbon scenarios of the future with innovative development and application of the three technologies forcarbon dioxide hydrogenation, carbon dioxide could be converted into syngas (CO+H2 ), so as to realize high value, resource utilization and carbon solidification and archive. In sddition, Fischer-Tropsch synthesis of high-carbon hydrocarbon fuels and carbon dioxide hydrogenation in the coal power, coal chemical and cement industries is not only a way of realizing the value from carbon dioxide, but also of peak regulation of the power grid. Similarly, the dry reforming of CO2 and CH4 into biogas and unconventional natural gas can produce green hydrogen, renewable fuels and methanol with high value, which is of special significance for China’s rural revitalization, and can open up rural waste treatment to energy transformation and enable national industry to generate supplementary value for agriculture. The funding related to this will also enable China’s rural revitalization projects to obtain new opportunities for capital. Through low-carbon transformation of the steel and chemical industries, the high-value utilization of carbon dioxide in dry reforming of coal gas and dry gas, especially the production of methanol by dry weight integration into gas, and carbon solidification via the production of ethylene, propylene and polymers by MTO, will enable CCUS to creat new opportunities along the industrial chain. In a sense,CCUS will become a subsidiary industry of all social activities and industries and, could be regarded as a new public service industry chain.
