Olivine Dissolution in Seawater: Implications for CO2

2017-3-10 · Weathering and subsequent pptn. of Ca- and Mg-carbonates are the main processes that control the CO2-concn. in the atm. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO2-levels. This can be applied as a technol., by reacting captured CO2 with olivine or calcium-silicates in autoclaves.

Continuous flow synthesis of ZSM-5 zeolite on the

Zeolites have greatly contributed to modern industries. Consumption of zeolites is expected to increase with the emergence of newly commercialized applications. Typical synthesis of zeolites relies on batchwise hydrothermal synthesis, which usually takes tens of hours or even several days to complete. People have thus long believed that the crystallization of zeolites is very slow in nature.
