Abstract

Simulated waste-derived synthesis gas has been tested for hydrogen production through water gas shift (WGS) reaction in the temperature range of 350-550 C over chromium free Fe/Al/Cu oxide based catalysts. The CuO loading amount was optimized to get highly active Fe/Al/Cu oxide based catalysts for the high temperature WGS. Despite the high CO content in the feed gas (38.2 % dry basis), 15 % CuO catalyst exhibited the highest CO conversion (86 %) and 100 % selectivity to CO2 at a very high gas hourly space velocity (GHSV) of 40,057 h-1 due to easier reducibility, the synergy effect of copper and aluminum, and the stability of the active phase (magnetite: Fe 3O4).
