Patent Abstracts

An aqueous solution of NH₄HCO₃ is decomposed at 1,500º-1,600º over alumina to CO and H₂ and the gas mixture converted over Co or Ni catalysts into hydrocarbons. The residual CO is converted to CO₂ and then with aqueous NH₃ to NH₄HCO₂. The alumina mass is made of alumina, C, and binder and then converted by the decomposition of NH₄HCO₃ is gaseous NH₃ and water vapor as well as to NaAlO₂ liquor, which is split by CO₂. The Al₂O₃ H₂O formed thereby is dehydrated and agglomerated. The soda solution is causticized with Ca(OH)₂ and the CO₂ evolved changed with gaseous NH₃ to NH₄HCO₃. The NaOH is returned to the AIN decomposition.
