摘要：

Various platinum supported catalysts, with low metal loading (<1 wt.-%) have been studied in the gas phase hydrogenation of 1,3-butadiene, at 333 K, under 101 kPa pressure of hydrocarbon and using a feed corresponding to PH/PHC=3, argon being used as balance. The acidic properties of the support modify both the initial selectivity for the hydrogenation of 1,3-butadiene to butene and the internal butene distribution. It also has a marked influence on the variations of the rate of 1,3-butadiene consumption with time. Catalysts supported on materials having a basic character are more selective for butene production and more specific for 1-butene formation. In addition, preadsorption of ammonia on platinum supported over acidic supports leads to an increase in butene selectivity. © 1990.
