Scale-up of the carbonate looping process to a 20 MWth pilot plant based on long-term pilot tests An efficient post-combustion capture technology is the carbonate looping (CaL) process reducing the amount of CO2 released by fossil fuelled power and indu... Hilz, JochenHaaf, MartinHelbig, Mar...
The Ca looping process offers many advantages over the other CO2 capture technologies, such as a relatively small decrease in power plant efficiency and a potential for is further reduction. However, calcium sorbents in the consecutive cycles of adsorption and regeneration by calcination undergo deactiv...
Steel slag is a prospective CO2 capture material due to its substantial yield and calcium-rich mineral content. Numerous scholars have researched methods to enhance CO2 adsorption capabilities, including fine-tuning adsorption process parameters and modifying the steel slag. However, the limited presence...
A screening of potential calcium precursors for the production of CaO sorbents for CO(2) capture at high temperature was conducted in this work. The precursors studied include microsized calcium carbonate (CC-CaO), calcium hydroxide (CH-CaO), nanosized (<70 nm) calcium carbonate (CC70 nm-CaO...
Performance study of modified calcium magnesium acetate (MCMA) in the process of high temperature CO2 capture and the application of spent MCMA for sequent... The modified calcium magnesium acetate (MCMA) has the similar characteristics and properties to those of CMA and a lower production cost...
Calcium-Looping is a highly efficient process which uses broadly available natural limestone as a CO2 sorbent. The process uses the reversible reaction (CaCO3 ↔ CaO + CO2) between calcium carbonate and calcium oxide in the temperature range of 650 and 900 °C. This publication presents the ...
In order to improve the cycle stability of the adsorbents and the capture efficiency of CO2, this study used industrial solid waste coal fly ash for the hydration treatment of calcium-based adsorbent to explore the variations in the cyclic adsorption performance of the adsorbent under different ...
Hence, the aim of this study, is a lab-scale integration of CO2 capture strategy based on chemical absorption with semibatch crystallization process of calcium carbonate. Here, the focus is to provide a detailed insight into kinetics of the crystallization mechanism from the carbon utilization ...
