Carbon Dioxide Utilization

only utilizes CO2, but also avoids using fossil feedstock and creating CO2 emissions. It has been estimated that the various chemical conversion pathways can consume approximately 0.3 to 0.7 Gt/y of CO2 [8]. Conversion of CO2 into inorganic minerals that may be used in building materials is being pursued by some companies [9].

Feedstock Coal - Carbon Dioxide - Brian Williams

Oct 05, 2020· As for potential CO2 utilization, the situation with coal is similar to that of biomass. The feedstock is poor in hydrogen, so syngas H2 content must be increased by shift conversion of CO, leading to high amounts of CO2 that are ultimately emitted to the atmosphere. Resulting carbon utilization and energy efficiencies are low (Table 1), leading to high extra-fossil CO2 emissions.
