6 Claims. (Cl. 196-10) This invention relates to the conversion of been heated in the heating coil 2, such. gas will highly volatile hydrocarbon constituents of natremain in such heated condition in the vessel ural gas into comparatively less volatile hydrofor an appreciable period of time, preferably carbon liquids. An object of my invention is to in excess of two minutes, before flowing into 5 change the molecular arrangement of carbon the condenser worm 7. A part of the gas which 5 and hydrogen in some of the constituents of will pass from the vessel 5, through the pipe 6 natural gas to produce gasoline.

A pipe 4, leads from the outlet of heating coil Steam will be passed through the heating coil 20 2, into the top of a vertical cylindrical closed 14, which will heat and vaporize a part of the vessel 5. A pipe 6, leads from the bottom of the liquid which Will gather in the bottom 0f the vessel 5, into a condensing worm 7. A pipe 8 fractionating column 12 and vapors thus proleads from the outlet of condenser worm 7 into duced will rise through the fractionating column a closed cylindrical vessel 9. A pipe 10 in which and will pass thence through the pipe 20, into 25 is mounted a valve 11, leads from the bottom of the pipe 19 where such v p w limin le wi h vessel 9, into the top of a fractionating column the natural gas which will flow through the pipe 12.

The rate at period of time in the vessel 5, will be changed in which gas will be pumped through the heating such a way that comparatively less volatile hycoil and the closed vessel 5 into the condenser drocarbons will be formed from the hydrogen worm '1 will be such that after this gas has and carbon present in the natural gas while at 55 the same time hyrogen will be liberated from the natural gas and hydrocarbon gases, which are more volatile than was the original natural gas, will also be formed. After this molecular rearrangementof the elemental constituents of the natural gas has taken place in the vessel 5, the
resulting liquid and gases will be passed through the remainder of the process, as has been described, for the purpose of recovering the desirable products which will have been thus produced.
While I have described in considerable detail one method of carrying out my new process, it is to be understood that I do not intend that I shall be limited by these details, but intend to claim all novelty which is inherent in my inveninch, continuously feeding said compressed gas through a heating zon maintained at a temperature above 750 F., maintaining the gas in said heatedand compressed state for a time sufficient to convert a portion, of the gas into liquid hydrocarbons, separating the resulting mixture into fixed gasbgasoline and a hydrocarbon fluid heavier than said fixed gas and lighter than said gasoline, releasing the fixed gas substantially constantly from the process, returning the hydrocarbon fluid for admixture with the fresh hydrocarbon gas, and withdrawing gasoline from the process.
