The cement industry is already active in R&D for CO 2 capture. Up to now, pre-combustion technologies have never been used in a cement plant. Oxy-fuel technology is a candidate for CO 2 capture at cement kilns. There are experiences from cement kilns in the USA which were operated with oxygen enrichment (to increase the production capacity)
Our main product categories include stone crusher machine, sand making machine, ore beneficiation plant, powder grinding machine, dryer machine, etc. We can provide not only single machine, but also complete production plant with our powerful technical support. If you are interested in our company and our products, you can click to consult, we will provide you with value-for-money equipment and considerate service.

Sep 16, 2019 Caption: In a demonstration of the basic chemical reactions used in the new process, electrolysis takes place in neutral water. Dyes show how acid (pink) and base (purple) are produced at the positive and negative electrodes. A variation of this process can be used to convert calcium carbonate (CaCO3) into calcium hydroxide (Ca(OH)2), which can then be used to make Portland cement without
