Hello all,

I'm a newcomer to the chemical research field, thought reading paper was the first step for me to make progress, but found lots of things being confused.

One of them is:

I saw lots of papers discussed the reaction conditions using WHSV and molar ratio of two different feed.

I knew the knowledge of conducting experiments from high school by hold all conditions the same except changing one of them. That's the basic, natural conditions such as temperature, catalyst mass, feed rate...

My question is why to use WHSV and Molar Ratio here, which are compounded properties instead of natural ones.

Also, If I make different combination to make WHSV and MR the same, will the results of the experiments keep the same?

Thanks so much,
Vincent
