Patent Abstracts

Heat required for initiation of gaseous exothermic catalytic reactions carried out under pressure at high temperatures is supplied from an auxiliary catalytic exothermic reaction of like gases, to which other gases may be added temporarily id desired, which serves to heat initially the apparatus and catalyst used for the main reaction. Describes various details of apparatus and procedure. In the production of NH₃ from a N₂H₂ mixture derived from water gas, the amount of CO purification may be reduced and the gases passed over a low-temperature CH₄-forming catalyst to initiate the NH₃ synthesis. Describes production of homologs of MeOH from CO and H₂ also.
