Reactions of calcium oxide with carbon dioxide and with sulfur dioxideZawadzki, JBretsznajder, S
sodium hydrosulphite, separated from insoluble matter and then treated with carbon dioxide or the carbonate of the amine or alkanolamine at a temperature of at least 50掳 C. Preferably, the amine of the salt and of the carbonate are the same, and the salt is used in at least the ...
The thermal performance of a chemical heat pump that uses a calcium oxide/carbon dioxide reaction system was discussed as a heat storage system for utilizing heat output from high temperature gas reactors (HTGR). Calcium oxide/carbon dioxide reactivity for the heat pump was measured using a packed...
thus paving the way for the possible use of these matrices for applications in the field of sensor devices for long-term evaluation of accumulated environmental CO 2 . Keywords: sensors; carbon dioxide; calcium oxide; composites; nanogravimetry 1. Introduction The relentless World population increase...

In particular, the invention is directed to materials and methods for decomposing calcium carbonate into calcium oxide and carbon dioxide at an elevated temperature, reacting calcium oxide with ammonium chloride to form calcium chloride, water, and ammonia gas; and reacting ammonia gas and carbon ...
The influence of carbon monoxide on the reaction between sulphur dioxide and calcium oxide The influence of carbon monoxide on the reaction between SO2 and CaO prepared from reagent grade CaCO3 and two different naturally occurring limestones was... SG Lindqvist - 《Thermochimica Acta》 被引量: ...
HistoryCalcium oxide dates from prehistoric times. It is produced by heating limestone to drive off carbon dioxide in a process called calcination: CaCO3(s)CaO(s)+ CO2(g). At temperatures of several hundred degrees Celsius, the reaction is reversible and calcium oxide will react with atmospheric...
Replace the cover glass and return the beaker to the steam bath, heating until all reaction has ceased. Rinse and remove the cover glass and evaporate to dryness. Dissolve the residue in about 100 ml of water, acidifying with a few drops of hydrochloric acid if necessary. Make the solution...
