In a process for reacting two or more gaseous reactants to form at least one product with the evolution or absorption of heat, the improvement comprises adding at least one compound to the reactants in an amount sufficient to reduce the temperature change of the overall process by at least 15% of the temperature change that would have occurred had the at least one compound not been added, the at least one compound having a molar specific heat of at least 50% greater than that of the reactants evaluated at the same reaction temperature. The process is used particularly for the synthesis of methanol, ammonia, SNG or ethylene oxide. A preferred added compound is cyclopentane. For processes in which unreacted gases are recycled, the condensing out of the added compound prior to condensing out of the product is also described. |
