Monitoring of Impacts of Offshore Platforms in the Adriatic Sea (Italy)

Abstract

© 2017 American Scientific Publishers All rights reserved. La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3− δ (LSGM) based fuel cells infiltrated with different metal catalysts were fabricated and tested both in H 2 and CH 4 /CO 2 mixture. Ni, Co, Ni–Cu, Ni–Co LSGM impregnated powders were investigated for the dry reforming of methane reaction (DRM) (CH 4 +CO 2 ⇆ 2CO+2H 2 ). The catalytic activity for CH 4 and CO 2 conversion followed the order Ni∼Ni–Co > Co > Ni–Cu. Both Ni and Ni–Co catalysts, investigated versus time (50 hours) on stream of CH 4 /CO 2 = 1.5 at 800 °C, did not show any sign of deactivation indicating their stability toward coke deposition. Anyway, evidence of few carbon filaments were revealed by SEM micrographs and the carbon amount evaluated by TG-DTA analysis. Ni-LSGM and Ni–Co LSGM cells showed regarding electrochemical performance both in H 2 and CH 4 /CO 2 mixture in the 650–750 °C temperature range.
