Hydrocarbon conversion process

摘要

The invention relates to processes for converting a mixture of hydrocarbon and oxygenate into products containing acetylene and carbon monoxide. The invention also relates to utilizing at least a portion of the acetylene and carbon monoxide for producing xylenes such as p-xylene, utilizing at least a portion of xylenes for producing polymeric fibers, and to equipment useful for these processes.

主权项

1. A hydrocarbon conversion process, comprising:
(a) providing a first mixture, the first mixture comprising ≧25.0 wt. % of methane, ≧5.0 wt. % molecular hydrogen, and an oxygenate, the oxygenate comprises ≧10.0 wt. % of carbon dioxide and/or carbon monoxide, the weight percents being based on the weight of the first mixture; (b) exposing the first mixture to a temperature ≧700° C. in a first region under pyrolysis conditions to produce a second mixture, the second mixture comprising molecular hydrogen, carbon monoxide, and ≧1.0 wt. % of acetylene based on the weight of the second mixture, wherein the second mixture has a molecular hydrogen:carbon monoxide molar ratio ≧2.0 and a carbon monoxide:acetylene molar ratio ≧0.1; (c) converting at least a portion of the second mixture's acetylene to produce a first intermediate mixture comprising ≧10.0 wt. % aromatic hydrocarbon based on the weight of the intermediate mixture; (d) reacting at least a portion of the second mixture's carbon monoxide with at least a portion of the second mixture's molecular hydrogen to produce a second intermediate mixture comprising ≧10.0 wt. % alcohol based on the weight of the second intermediate mixture; and (e) reacting at least a portion of the first intermediate mixture's aromatics with at least a portion of the second intermediate mixture's alcohol to produce a product comprising water and ≧10.0 wt, % p-xylene based on the weight of the product.
