Yes, but what gas? Maybe the title should have said either "useful" or at least "harmless" gas. The gases that come from basic polymers could be comparable in those ways, to the original petroleum. They could even be reformed into new polymers, or used as fuel.

By way of contrast: Vaporizing lead or mercury compounds, not such a good idea.

Notably the easiest way to not run afoul of those rules is to not modify the title even if the original title is bad. You do have to squash titles down to the 80 char limit and the same way to do that is delete words, preferable noise words like “very” or “novel” and past that more complex transformations where you maybe change a passive construction into a shorter active construction.
