      Not only, as a present, can the Fischer synthesis be used to produce liquid fuels, certain fractions of which are rich in olefins useful for the manufacture of lubricating oils and paraffins subject to oxidation into fatty acids, but also it will be only a question of time and research until gases will be produced that are rich enough in mono-olefins to be polymerized into high-octane gasolines.  Another revolution will be accomplished if conversion of CH₄ and its homologs into olefins can be carried out commercially. This is important to both the oil and the coal industries – to the former because of the immense quantities of CH₄ contained in natural gas and to the latter because of the high % of CH₄ in coke-oven gases.
