ABSTRACT:
A process for converting natural gas to liquid hydrocarbons comprising heating the gas through a selected range of temperature for sufficient time and/or combustion of the gas at a sufficient temperature and under suitable conditions for a reaction time sufficient to convert a portion of the gas stream to reactive hydrocarbon products, primarily ethylene or acetylene. The gas containing acetylene may be separated such that acetylene is converted to ethylene. The ethylene product(s) may be reacted in the presence of an acidic catalyst to produce a liquid, a portion of which will be predominantly naphtha or gasoline. A portion of the incoming natural gas or hydrogen produced in the process may be used to heat the remainder of the natural gas to the selected range of temperature. Reactive gas components are used in a catalytic liquefaction step and/or for alternate chemical processing.
