Thoughts for New Carbon Sequestration Technology and Technical Research

The research progress of carbon sequestration technology was summarized.From the aspect of resource utilization,carbon dioxide(CO2)is a“carbon source”with massive amount of inventory.Chemical carbon sequestration technology had advantages in both carbon emission reduction and resource utilization,being the key development trend of the future carbon sequestration technologies.Based on the current technical problems and achievements of the chemical carbon sequestration,combining the CO2 utilization process and current new material synthesis process,a new carbon sequestration technology was proposed to use CO2 as fundamental raw material to produce polycarbonate by deeply extending the industrial chain,forming the diverse product structure and commercial availability.The technical feasibility analysis was made on those main processes involved in the new technology,such as urea production from CO2,dimethyl carbonate(DMC)production from urea,diphenyl carbonate(DPC)by transesterification reaction,phenol production by cumene process,bisphenol A(BPA)production by ion exchange resin,and non-phosgene polycarbonate synthesis.
