Abstract
Pb, Sb, Bi and Te doped Ni catalysts were prepared and used for methane reforming with CO2 in order to diminish coke deposition. It was found that small amounts of Pb doped Ni catalysts exhibited excellent coke resistance ability with minor loss of the reforming activity. As the added amount of Pb increased from 0 to 0.015 (mole ratio between Pb/Ni), coke formation rate decreased from 166.7 mg-coke/g-cat h (on Ni/SiO2) to 0, while the reforming activity decreased slightly from 73.2% to 63.3% (conversion of CO2) at 800 °C, 60,000 ml(STP)/g-cat·h (CH4 CO2=1:1, no dilution gas in feed). Higher amounts of Pb and Sb, Bi, Te made Ni catalyst deactivated for methane reforming with CO2.
