▎ 摘  要

NOVELTY - Treatment of carbon dioxide involves preparing an aqueous dispersion containing magnesium hydroxide and 10-40 wt.% acetonitrile, and contacting the aqueous dispersion and a gas containing carbon dioxide to react magnesium hydroxide and carbon dioxide. The aqueous dispersion further comprises 2-8 wt.% hexamethylphosphoric triamide, and 30-90 wt.% of at least one hydroxide chosen from zinc hydroxide, sodium hydroxide and calcium hydroxide. USE - Treatment of carbon dioxide generated by burning liquefied natural gas, liquefied petroleum gas, heavy oil, gasoline, light oil and coal during thermal power generation. ADVANTAGE - The method treats carbon dioxide by finely adjusting the processing speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the aqueous dispersion.
