troubles inseparable from the storage of light naphtha in bulk.

In using this oil as an enricher, it must be cracked in the presence
of carbon, and it is of the greatest importance that the temperature
should not be too high, as the benzene is easily broken down to
simpler hydrocarbons of far lower illuminating value. This fact is
very clearly brought out by a series of experiments I have made, in
which the phenoloid oil was cracked by passing it through an iron tube
packed with coke and heated to various temperatures, the hydrocarbons
being much more easily broken up under these conditions than if mixed
with diluents, such as water gas:
