Evaluación de la estructura porosa de los materiales MCM-22, MCM-36 e ITQ-2 empleando el test catalitico del n-decano/ Evaluation of the pore structure of MCM-22, MCM-36 and ITQ-2 materials using the n-decane catalytic test

Resumen en inglés The void structure of zeolites MCM-22, MCM-36 and ITQ-2 were discussed on the bases of catalytic reaction tests. The hydromerization of n-decane on bifunctional Pt/Zeolite Catalysts have been used as model reactions. Beta and ZSM-5 zeolites were used for comparison. It is concluded that all materials show features of 10MR zeolites and have also pores bigger than 12MR in this order MCM-22

Resumen en español El objetivo de este trabajo fue estudiar el efecto de la concentración de un surfactante no iónico en agua sobre la tensión interfacial de una serie de alcanos. Para este propósito se seleccionaron el Triton X-100 y los alcanos: hexano, heptano, octano, decano, undecano y dodecano. Las pruebas se realizaron a una concentración 10-3, 10-4 y 10-5 mol/L y se empleó el método de la gota emergente para el cálculo de la tensión interfacial. Se observó que la tensión (mas) interfacial de las soluciones de Triton X-100 en agua decrece a medida que la concentración de surfactante en solución aumenta. Se concluyó que el valor de la tensión interfacial es función de la concentración, del tiempo de exposición de la interfase con la disolución y del volumen inicial de la gota al momento de iniciar la medida Resumen en inglés The objective of this work was to study the effect of the concentration of a non-ionic surfactant in water on the interfacial tension of an alkane series. For this purpose Triton X-100 and the alkanes: hexane, heptane, octane, decane, undecane and dodecane were selected for analysis. The tests were done at concentrations of 10-3, 10-4 and 10-5 mol/L and the emergent drop model was employed for the calculation of the interfacial tension. In this work it was observed that t (mas) he interfacial tension of the Triton X-100 solutions in water decreased as the concentration of the surfactant increase. It was concluded that the interfacial tension value is a function of the concentration, the exposure time of the interface with the dissolution and the initial volume of the drop at the moment when the measurement starts
