hypothesis to explain a more efficient biological carbon (C) pump and the associated drawdown of atmospheric CO2. Yet, modelling focussed on the high latitudes has sequestered less than 10 ppm of atmospheric CO2via Fe fertilisation5,6,7and indicates that additional biological mechanisms are required...
The project adopts a two-phase absorbent with low energy consumption to capture CO2, and the regeneration energy consumption of such absorbent is less than 2.4 gigajoule per tonne, reaching the advanced level globally. The captured CO2 is then used to produce industrial products with wide applicatio...

These only occur in the cases of low concentrations of CTAC (less than 10 wt%) or low concentrations of base (less than 5 wt%). When the CTAC concentration is above 10 wt%, excess CTAC can stabilize smaller toluene droplets within the water droplets, forming oil-in-water-in-oil...
In addition, the cost analysis indicates that slag-bond concrete blocks cost less than commercial cement blocks if produced in large quantities. Up to now, lots of carbon-capture construction materials have been obtained from steel slag carbonation, such as blocks [[40], [41], [42]], ...
