Abstract:

The Ni(II)Mg(II)Al(III) LDH were obtained by homogeneous precipitation urea method, after a proper thermal treatment resulted in an active catalyst for the ethanol steam reforming. After catalytic performance, catalysts were analyzed by temperature programmed oxidation (TPO), in order to quantify carbon deposits. Reduced Ni area was evaluated by H2 static volumetric chemisorption measurements in a Micromeritics AutoChem II 2920 equipment. Thermogravimetric studies were carried out in a Shimadzu TGA-51H equipment, using a heating ramp of 10 K/min in air flow of 50 cm3/min. Experimental equipment used for catalytic evaluation consists of a quartz tubular reactor heated in electric oven at the reaction temperature, which is monitored by a thermocouple placed inside the reactor. The vaporized current is diluted with argon at the entrance of the reactor. It can be observed PXRD spectra of precursors with different Mg content, all samples show characteristic signals of LDH.
