The experiment shows that plasma power load, i.e. the ratio of methane flow to plasma power, is the most important factor effecting methane dehydrocoupling. The products of the reaction are mainly acetylene, ethylene, ethane and unreacted methane etc. If oxygen with a suitable molar ratio is introduced into plasma region at a reasonable position, the selectivity of C2 hydrocarbons can be increased greatly.展开更多

The experimental results show that the temperature of n-heptane is the first major factor affecting formations of heptanol and heptanone, and then oxygen flow and plasma power etc. follow in proper order. Under a typical condition the selectivity of product formation is far superior to that of plasma oxidation in the gas phase.展开更多
