Endothermic hydrocarbon upgrading process
Patent
·
OSTI ID:6593399
This patent describes a process for upgrading aliphatic hydrocarbons to aromatic hydrocarbons. It comprises: burning a hydrogen-deficient fuel under oxygen-deficient conditions to evolve a hot gas containing essentially no oxygen; providing an aromatization reaction zone containing a zeolite catalyst; directly transferring a quantity of thermal energy from the hot flue gas to the aromatization reaction zone by flowing hot flue gas through the aromatization reaction zone; contacting an aliphatic hydrocarbon feedstream with the zeolite catalyst under primary conversion conditions in the aromatization reaction zone to evolve an aromatization reaction zone effluent stream containing aromatics; withdrawing the aromatization reaction zone effluent stream from the aromatization zone; separating the aromatization reaction zone effluent stream into a product stream, a secondary conversion feedstream comprising CO, CO{sub 2}, and H{sub i} and a stream containing C{sub 3}-C{sub 5} aliphatics; and charging the secondary conversion feedstream to a methanol synthesis reaction zone to convert at least a portion of the secondary conversion feedstream to methanol.
