   One works according to this process practically as follows: A mixture of calcined soda from the trade with a little more than one equivalent of dried hydrated lime is loosely filled into pressure-proof, heatable cylinders and at a temperature of 150-1700 C carbon oxide with some water vapor under a pressure of Allowed to act for 7-10 atmospheres.
 EMI2.1
 can be changed and when using non-pure carbon dioxide, the gas can flow through these cylinders under pressure.
