Abstract

The hydroconversion of n-C10 was studied over functionalized AlMCM-41 with platinum rate exchange (0.5—4 wt%) and ammonium ions (95%). The n-C10 underwent conversion with bi-functional catalysts Pt/H-AlMCM-41. The tests were carried out in a continuous fixed bed reactor under the following conditions of atmospheric pressure, ratio alkanes/H2 5:1, temperature (up to 600 °C), acidity and space velocity (0.1 h−1 < WHSV < 2.1 h−1). Relatively high yields of light products were obtained. Ptn+/H-AlMCM-41 catalysts showed a good catalytic activity. The study revealed bimodal distribution; the adsorption of n-alkanes on acids sites and then their subsequent conversion. Thus; this phenomenon is improved by the textural/ structural characteristics and (Ptn+/H) bi-functionalization, responsible for the acidity on the inner surface of catalysts. This work has established a close relationship between structure, selectivity, activity and acidity of functionalized AlMCM-41. The nature and distribution of the obtained products suggest that the bifunctional catalysts show a good performance and better selectivity in hydrocracking reactions than hydroisomerization with its accompanying steric effects biased for multibranched products.
