摘要: Abstract The highly dispersed mNi/xLa−Si catalysts with varied weight percentages of Ni and La were synthesized via one-pot sol-gel process subsequently applied to combined carbon dioxide steam reforming methane (CSDRM) for syngas production. addition improved the catalytic activity stability as well coke resistance catalysts. effects preparation routes, contents CO2/steam (C/S) ratios on performances Ni/La Si studied in detail CSDRM. 17.5Ni/3.0La catalyst assistance poly (ethylene glycol) ethylene glycol exhibited most excellent activity, resistance. In addition, H2/CO product gas could be tuned by changing C/S feed. When ratio was 0.5, about 2 achieved catalyst.
