US 2003/0144565 A1 · Non-oxidative conversion of gas to liquids

Abstract

he present invention provides a process for natural gas in the form, e.g., of stranded gas or associated gas to transportable liquids. More particularly, the present invention provides a process in which the gas is non-oxidatively converted to aromatic liquid, preferably in proximity to the wellhead, which may be onshore or offshore. In one aspect, the present invention provides integration of separation of wellhead fluids into associated gas and crude with blending of the aromatic liquid derived from the gas with the crude. Alternatively, or in combination, in another aspect, the present invention provides integration of conversion of byproduct hydrogen to power with non-oxidative conversion of gas to aromatic liquid.

Dependent claims

A process for converting a gaseous hydrocarbon stream to an aromatic hydrocarbon stream, comprising:

(a) passing the gaseous stream from a wellhead to a non-oxidative conversion zone proximous to the wellhead;
and
(b) contacting the gaseous stream with a catalyst so as to produce the aromatic liquid stream, wherein the catalyst is contained in the conversion zone.

Dependencies are inferred from the claim text.
