Chemically react, and continue to increase the pore pressure on stratum, this will destroy the physics such as original stress, temperature, osmotic pressure
Chemical balance, its long-term geology brought influence to be difficult to estimate.
CO2Itself is also a kind of valuable carbon resource, how reasonably to utilize CO2Resource is one of the world today important
Research topic.Because new energy can not possibly substitute fossil feedstock, CO in short-term2Geological storage technology and consequent effects also have
Treat in research, CO2Chemical conversion will following reduce CO2One important channel of discharge capacity.CO2Chemical conversion refer to
CO2For raw material, by a series of reaction, refer to be converted into valuable chemical intermediate or chemicals.CO2Chemical conversion
Accomplish that change " useless " truly into " treasured ", realizes CO2Recycling, be current CO2The foreword heat of research field
Point.
