DIOXIDE AND CARBON POWDER
[01] The present invention relates to a method for reducing carbon monoxide synthesis gas with high temperature melting heat carrier and carbon dioxide and carbon powder.

At present, the carbon dioxide involved mainly considers the use of slag low temperature section to absorb carbon dioxide (carbon sequestration) emission reduction, environmental protection and energy saving facilities, and the reaction heat generated when slag and waste gas undergo carbonization reaction. The heat generated is reacted with carbon dioxide and carbon to form carbon monoxide, the carbon dissolution doss reaction reduces carbon dioxide deficiency and the lack of effective utilization of high-temperature high-quality resources above 1000 °C for high-temperature molten heat carrier. In view of the lack of more in-depth research on the basis of our small test on the production of high-content carbon monoxide synthesis gas by injecting carbon powder and carbon dioxide into the molten carbide heat carrier, and the lack of energy conversion in the experiment of reducing carbon monoxide with carbon dioxide and carbon powder in a resistance wire heating fluidized bed is unscientific and not in line with environmental protection and clean production, It is imperative to invent a method for reducing carbon monoxide synthesis gas with high temperature melting heat carrier and carbon dioxide and carbon powder.
[03] The present invention realizes the staged recovery of heat energy of the high-temperature molten heat carrier, the organic combination of high temperature carbon dioxide reduction to carbon monoxide above 1000°C and strong latent heat of solidification of molten heat carrier and strong exothermic heat transfer realizes carbon dioxide instead of air to circulate heat for high temperature particles. Make full use of the characteristics of carbon dioxide gas volume and high specific heat capacity, reduce the circulation volume of gas volume heat exchange, reduce power consumption and miniaturize equipment. A method for reducing carbon monoxide synthesis gas with high temperature melting heat carrier and carbon dioxide and carbon powder is proposed, which can improve carbon dioxide emission reduction, reduce heat pollution, water

BL-5424
LU501529 space. À small amount of carbon dioxide and carbon powder are reduced to carbon monoxide (the buffer space is catchy, and the conversion rate 1s low), a part of carbon dioxide gas (controlled gas) enters the rotary granulation space through the upper opening of the buffer space.
