CO2 Reforming of CH4 in Coke Oven Gas to Syngas over Coal Char Catalyst
The CO2 reforming of methane (in coke oven gas) on the coal char catalyst was performed in a fixed bed reactor at temperatures between 1073 and 1473 K and normal pressure. The effects of the coal char catalyst pretreatment and the ratio of CO2/CH4 were studied. Experimental results showed that the coal char was an effective catalyst for production of syngas, and addition of CO2 did not enhance the CH4 reforming to form H2. It was also found that the H2/CO product ratio is strongly influenced by the CO2/CH4 feed-ratio.The modified coal char catalyst was more active during the CO2-CH4 reforming than the coal char catalyst based on the catalyst volume, whereas the modified catalyst exhibited stable activity for syngas production in methane and CO2 conversion after 500min of reaction.
