Methane is an odorless gas; the smell referred to arises from various
aldehydes, ketones, and carboxylic acids present in the "natural" product.

I'm more curious as to how the CO2 is separated from the O2; under these
conditions hydrogen reacts vigorously with oxygen and would use large
amounts of both to reduce a small amount of CO2 unless some
preconcentration takes place.
