GAS MIXTURE FOR THERMOCHEMICAL TREATMENT OF METALS AND ALLOYS, PROCESS AND APPARATUS FOR PREPARING SAME A B S T R A C T A gas mixture for a thermochemical treatment of me- tals and alloys comprising the components in the following proportions, % by volume: carbon monoxide 50.0 - 61.5 hydrogen 38.5 - 50Ø A process for preparing said mixture comprising con- version of saturated hydrocarbons containing one to four carbon atoms with carbon dioxide in the presence of a nick- el-containing catalyst heated to a temperature of 1.123- -1.373 K and used in an amount of from 1 to 4 parts by volume of said hydrocarbons. An apparatus for preparing said gas mixture comprises a converter with a catalyst located coaxially with a hous- ing with the formation of an annular clearance and a mixer communicating with an inlet pipe of said converter. The con- verter has an outlet pipe communicating with a consumer. Positioned in the annular clearance are heating members connected to a source of current and having power decreas- ing across the height of the catalyst bed in the direction of the gas flow. The mixer is connected to a vessel with carbon dioxide. The present invention can be most advantageously used in processes of a thermochemical treatment of metals and al- loys thereof.
