摘要：
The kinetics of CH4 partial oxidation was investigated in a structured reactor at high space velocity under well-controlled operating conditions. High temperatures favored the production of CO and H-2. At increasing space velocity, CO and H-2 selectivities showed a moderate and a strong decrease respectively. Increase Of O-2/CH4 feed ratio caused a shift to higher temperatures of methane conversion and syngas production. These effects could be accounted for by a simplified kinetic scheme, which includes methane deep oxidation, steam and dry reforming, WGS and the consecutive oxidations of CO and H-2.
