"Scientific American Supplement, No. 794, March 21, 1891"

Showing that, if the Russian oil is a little lower in illuminants, it
quite makes up by extra volume, but it seemed to me to deposit a much
larger proportion of carbon.
Taking 21/2 gallons of American naphtha, it would give roughly 180 cubic
feet of gas of the above composition, while the remaining gas would be
the ordinary water gas. Taking the analysis of this as given, and
calculating from it what would be the composition of a mixture of it
with the naphtha gas, we obtain:
Calculated. Actual.
Hydrogen...................... 47.09 42.09
Methane....................... 5.48 11.27
Olefines...................... 2.53 7.59
Ethane........................ 2.17 6.32
Carbon monoxide............... 30.07 18.65
Carbon dioxide................ 3.78 2.32
Oxygen........................ 0.56 0.17
Nitrogen...................... 7.17 8.25
Sulphureted hydrogen.......... 1.15 2.84

Showing how great the effect is of the diluents in the water gas in
preventing the overcracking of the hydrocarbons, as shown by the
increase in the percentage of them present in the finished gas; while
the enormous reduction in the amount of carbon monoxide present is due
to the interaction between it and the paraffin hydrocarbons in the
presence of red-hot carbon, a point which makes the Van Steenbergh
apparatus enormously superior to any of the superheater forms of
plant.
