Abstract:
A process for producing naphthalene or methylnaphthalenes from an alkane-containing stream. In an embodiment, the produce includes providing an alkane-containing feed stream to a reactor, and contacting the ethane-containing stream with an aromatization catalyst within the reactor. The aromatization catalyst comprises molecular sieve, and a dehydrogenation component. In addition, the process includes producing a reactor effluent stream from the reactor, and separating a product stream from the reactor effluent stream. The product stream comprises at least one or both of naphthalene and methylnaphthalene.

Claim (Index 18):
A process, comprising:\n (a) providing a feed stream to a reactor, wherein the feed stream comprises a majority fraction of ethane; (b) contacting the feed stream with an aromatization catalyst within the reactor, wherein the aromatization catalyst comprises molecular sieve, and a dehydrogenation component; (c) producing a reactor effluent stream from the reactor; (d) separating the reactor effluent into a first stream and a second stream in a first separation unit, wherein the first stream comprises hydrogen and methane, and wherein the second stream comprises C 6 -C 8  aromatic hydrocarbons, naphthalene, methylnaphthalenes; (e) separating the second stream into third stream and a fourth stream in a second separation unit, wherein the third stream comprises a majority of the C 6 -C 8  aromatic hydrocarbons from the second stream and wherein the fourth stream comprises a majority of the naphthalene and methylnaphthalenes from the second stream; and (f) separating the fourth stream into a product stream and a residue stream in a third separation unit, wherein the product stream comprises one of a majority of the naphthalene from the fourth stream or a majority of the methylnaphthalenes from the fourth stream, and wherein the residue stream comprises the other of a majority of the naphthalene from the fourth stream or a majority of the methylnaphthalenes from the fourth stream.
