Abdullah Irankhah; Sepideh Ghafoori; atieh ranjbar

Volume 21, Issue 1 , February 2024

https://doi.org/10.22034/ijche.2024.428444.1508

Abstract
  In the present work, the effect of synthesis method (simultaneous impregnation and coprecipitation) and copper to nickel active phases loading were investigated in Ni-Cu-Al catalysts. The water/ethanol molar ratio of 6 and gas hourly space velocity (GHSV) of 20000 hr-1 were used in all the experiments. ...  Read More

Volume 16, Issue 4 , October 2019, , Pages 23-35

https://doi.org/10.22034/ijche.2019.133029

Abstract
  Micro-reformers used for producing hydrogen with a high surface-to-volume ratio in small-scale fuel cells were investigated. To this end, scrutinizing and exploiting all areas of micro reformers is very important. Parallel micro-channels have shown good performance in eliminating dead volumes. Inlet/outlet ...  Read More

Methanol Steam Reforming Catalyzing over Cu/Zn/Fe Mixed Oxide Catalysts

A. Irankhah; M. Jafari; M. Mahmoudizadeh

Volume 14, Issue 1 , March 2017, , Pages 26-39

Abstract
  Methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. To accomplish higher methanol conversion and lower CO production, the reaction was catalyzed by CuZnFe mixed oxides. Various ratios of Fe and Cu/Zn were coprecipitated in differential method ...  Read More
