Estudio del área superficial específica en la caracterización de los catalizadores a utilizarse en la gasificación catalítica para la producción de hidrógeno

Abstract

This research is developed as part of the characterization of the catalysts to be used in the Catalytic Gasification Reaction for the Hydrogen Production. Therefore, the study of the specific surface area of three supported catalysts: Al2O3 10%Ni, TiO2 10%Ni y ZrO2 10%Ni, synthesized by the incipient wet impregnation method. The process of activation by calcination of the catalysts was realized considering the time in heating ramp with variations of 1 and 2 hours and the residence time at temperatures of 500°C and 600°C with variations of 1 and 2 hours in each case. In the activated catalysts, the specific surface area is determined using the BET technique at 77K with liquid N2 in a NOVA Quantachrome 2200e Surface Area & Pore Size Analyzer physisorption equipment, obtaining the adsorption isotherms, with which the mesoporous nature of the sample. The influence of the calcination process on the specific surface area was analyzed. The catalyst with the highest specific surface area was TiO2 10% Ni, calcined for 2 hours in a heating ramp with a rate of 4.02°C / min and 1 hour of permanence at a constant temperature of 500°C.
