Abstract

Isomerization of n-pentane has been studied in a continuous-flow reactor at atmospheric pressure on Pt/Al2O3 catalysts modified by adsorbed bismuth and palladium. Lower activity and higher selectivity have been obtained on a catalyst modified by bismuth. Both activity and selectivity have decreased on a catalyst modified by palladium. After oxygen treatment the Pd−Pt/Al2O3 catalyst showed the most pronounced change in catalytic properties and its stability was lower than that of the unmodified Pt/Al2O3 catalyst.

Abstract

Изомеризация н-пентана была исследована в реакторе непрерывного потока, при атмосферном давлении и на катализаторе Pt/Al2O3, модифицированном адсорбированным висмутом и палладием. Пониженная активность и повышенная селективность наблюдались для катализатора, модифицированного висмутом. Как активность, так и селективность уменьшались в случае катализатора, модифицированного палладием. После обработки кислородом самые значительные изменения в каталических свойствах наблюдались для катализатора Pd−Pt/Al2O3 и его стабильность была меньше, чем для немодифицированного катализатора Pt/Al2O3.
