The steam reforming of simulated coke oven gas (COG) with toluene as a model tar compound for syngas production was investigated over Ni/Al2O3-MgO catalysts. XRD results showed that the catalysts with high calcination temperature and Al2O3 content after calcination formed (Ni,Mg)Al2O4 spinel and Ni-Mg-O solid solution structure. At optimized reaction conditions, toluene and CH4 can be completely converted, while a H2 yield of 71.8% and a CO yield of 76.1% have been achieved at 800 oC. The catalysts with appropriate calcination temperature and Al2O3 content showed better catalytic activity and resistance to coking, which will be promising catalysts in the catalytic reforming of COG.

The catalytic reforming of toluene was performed to investigate the possibility for directly converting tar components from hot coke oven gas (COG) with lower steam/carbon (S/C) molar ratio to light fuel gases. The Ni0.25Me0.25/Mg2.5(Al)O (Me=Fe, Cu, Zn, Mn) bimetallic catalysts derived from hydrotalcite showed excellent catalytic activity. The effects of various reaction conditions on the catalytic performance were investigated in detail. Toluene could be completely converted into small gas molecules of CH4, CO and CO2 over the catalyst at S/C=0.7 and 650-750 oC under atmospheric pressure. Lower reaction temperature and higher H2 content in feed gas both could promote the formation of CH4, while higher S/C molar ratio benefited the CO yield.

Pd (0.1-1 wt%) loaded Ni/Mg(Al)O catalysts have been prepared by co-precipitation and impregnation methods, and their catalytic activities were tested in the catalytic reforming of tar components from hot coke oven gas (COG) with lower steam/carbon (S/C) molar ratio. The 0.5%Pd-12%Ni/Mg3(Al)O bimetallic catalyst derived from hydrotalcite showed excellent catalytic activity. The effect of reaction temperature on the catalytic performance was investigated in detail. Toluene could be completely converted into small gas molecules of CH4, CO and CO2 over the catalyst at S/C=0.42 and 600°C under atmospheric pressure.
