Any method to in-situ absorb O2 in a high-temperature CO2/CO/O2 mixture?

Hi all, We are working on CO production from CO2 dissociation. In this system, the recombination of CO and O2 to reproduce CO2 at high temperatures (>1000 °C) severely limits the conversion of...

What is the specific definition of N2* (with a superscript asterisk )? and its difference with some excited metastable species (e.g., N2(A3), N2(a'))?

What is the specific definition of N2* (with a superscript asterisk )? and its difference with some excited metastable species (e.g., N2(A3), N2(a')). Is N2* just the joint name of all the N2...

In non-thermal plasmas, if the electron temperature is in the range of 1-2 eV, could species with an excitation threshold energy of 5 eV be formed?

In non-thermal plasmas, If the electron temperature is in the range of 1-2 eV, can species with a higher excitation threshold energy (e.g., 5eV) be formed through direct electron impact? or can...

Some kinds of plasmas are reported to have gas temperatures of larger than 2000 K, but why the electrode won't be melted?

Some authors reported that some kinds of plasmas (even for some non-thermal plasmas) have gas temperatures of larger than 2000 K, but if it is true, why the electrode (mostly made of ion with a...

How can I determine the flow rate of outlet gas in a plasma chemical reaction?

A problem that has been puzzling me is that, in a plasma-assisted chemical reaction, e.g. methane or methanol reforming, how to determine the flow rate of outlet gas which will be then used for...
