A process is disclosed for reversibly absorbing carbon dioxide to an alkali metal or earth alkaline absorbent. For absorption the absorbent is contacted with a first gas composition. For desorption the absorbent is contacted with a second gas composition. The moisture contents of the first and second gas compositions are controlled so that during the absorption step the absorbent is converted to a bicarbonate, and during the desorption step the absorbent is converted to a carbonate hydrate. Compared to prior art processes the process of the invention requires less energy input. The process of the invention is particularly suitable for producing a carbon dioxide enriched gas for accelerating plant growth in a greenhouse.

Moisture swing carbon dioxide enrichment process

An energy integrated process is disclosed for the conversion of carbon dioxide to a liquid product. The conversion reaction is exothermic. The heat of reaction and the heat of condensation of the reaction product or products are used as energy input in a carbon dioxide enrichment step. The enrichment step produces a feed gas for the conversion reaction.

Energy integrated carbon dioxide conversion process

A device is disclosed for conducting an adsorption/desorption swing reaction. The desorption step of the reaction is conducted at least in part at a temperature below 100&#xb0; C. Dry steam is used for purging the reactor and the adsorbent bed in the reactor. For this purpose the device has a water reservoir, and a vacuum source in fluid connection with the water reservoir and the reactor. During the desorption step the vacuum source causes water to evaporate, and the water vapor to flow through the reactor.
