Preserved Fulltext
Recebido em 20/10/10; aceito em 17/3/11; publicado na web em 5/5/11 Methanol steam reforming reaction was studied over Cu(5 wt.%)/CeO 2 with and without the presence of Zn. The Zn addition decreased the Cu +2 reducibility and increased the oxygen mobility of ceria. The main products were CO 2 and H 2 with small amount of CO. Selectivity to CO decreased with the Zn addition and it was lower at lower reaction temperatures and lower space velocities. At 230 ºC and W/F MeOH = 648 g min mol -1
