Answer 1

(this looks like a screenshot from GaBi)

Answer 2

Thanks for sharing. Not sure which database you are using but this scheme is indeed from GaBi. There is nothing in the box. It is just a way to display the inputs/outputs of the benzene production (hydrodemethylation of toluene) as modelled in GaBi.
