采用铁电填料床反应器，在N/sub /中研究了不同温度下甲烷、丙烷和新戊烷的CO/sub /重整反应。在非热等离子体中，这些碳氢化合物与CO/sub - 2/之间没有化学相互作用，它们的转化率随着对应碳氢化合物或CO/sub - 2/的增加而降低。H/sub - 2/产率也随CO/sub - 2/浓度的增加而降低。CO/sub - 2/和CH/sub - 4/均可生成CO，其产率随CH/sub - 4/浓度的增加而降低。H/sub - 2/与CO的摩尔比与底物烃和反应温度有关，随CO/sub - 2/浓度和反应器能量密度的增加而减小。烃的反应性依次为：丙烷、新戊烷、甲烷。随着反应温度的升高，烃转化率和H/sub - 2/产率均增加。反应温度控制着烃类二次分解和产物生成的后续和热过程，这些过程是由原位生成的自由基引起的。
CO/sub 2/ reforming of methane, propane, and neopentane was investigated with a ferroelectric packed bed reactor in N/sub 2/ at different temperatures. No chemical interaction was observed between these hydrocarbons and CO/sub 2/ in nonthermal plasma, and their conversions decreased with an increase in the counterpart hydrocarbon or CO/sub 2/. H/sub 2/ yield also decreased with an increase in CO/sub 2/ concentration. CO was formed both from CO/sub 2/ and CH/sub 4/, and its yield decreased with an increase in CH/sub 4/ concentration. The molar ratio of H/sub 2/ to CO depended on substrate hydrocarbon and reaction temperature, and decreased with increases in CO/sub 2/ concentration and reactor energy density. The reactivity of the hydrocarbon decreased in the order: propane > neopentane > methane. With an increase in reaction temperature, hydrocarbon conversion and H/sub 2/ yield increased. Reaction temperature controls the subsequent and thermal processes of secondary decomposition of hydrocarbon and product formation, which are induced by radicals generated in situ.
