N-pentane transformation over platinum supported catalysts on mesoporous molecular sieves SBA-15 with aluminum

Abstract:

N-pentane transformation in hydroisomerization conditions under H 2 flow at 300°C and dehydroisomerization at 500°C with H 2:N2 flow was carried out. Catalysts promoted with platinum over molecular sieves SBA-15 containing aluminum incorporated by direct synthesis and impregnation were used for this study. Incorporation of aluminum was effective, producing solids with catalytic activity for n-pentane transformation under the conditions evaluated. The presence of platinum in the catalysts produced a notable increase in the selectivity to pentenes for dehydroisomerization, while for the hydroisomerization showed a determinant role in the achieved conversion, with high selectivity to iso-pentane over the solid with aluminum incorporated by impregnation.
