A selective hydrogenation process is described. The process includes dissolving acetylene and hydrogen in a solvent to form a liquid feedstream. The solvent comprises a mixture of a polar organic solvent and a non-polar organic solvent. The liquid feedstream is contacted with a heterogeneous supported selective hydrogenation catalyst at selective hydrogenation conditions to convert at least a portion of the acetylene to ethylene forming a liquid reaction mixture comprising the ethylene produced.

Process for the selective hydrogenation of acetylene to ethylene

A new family of aluminosilicate zeolites designated UZM-44 has been synthesized. These zeolites are represented by the empirical formula.NaMTAlESiOwhere 'n' is the mole ratio of Na to (Al+E), M represents a metal or metals from zinc, Group 1, Group 2, Group 3 and or the lanthanide series of the periodic table, 'm' is the mole ratio of M to (Al+E), &#x201c;k&#x201d; is the average charge of the metal or metals M, T is the organic structure directing agent or agents, and E is a framework element such as gallium. UZM-44 has catalytic properties for carrying processes involving contacting at least one low carbon number aliphatic hydrocarbon having from 1 to about 4 carbon atoms per molecule with the catalytic composite comprising UZM-44 to produce at least one aromatic hydrocarbon.

A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts in processes for converting at least one aliphatic hydrocarbon having from 1 to about 4 carbon atoms in a feedstream to provide at least one aromatic hydrocarbon. These zeolites are represented by the empirical formula.NaMTAlESiOwhere M represents zinc or a metal or metals from Group 1, Group 2, Group 3 or the lanthanide series of the periodic table, T is the organic structure directing agent or agents and E is a framework element such as gallium. The process involves contacting a low carbon number aliphatic hydrocarbon with the coherently grown composite of TUN and IMF zeotypes to produce at least an aromatic.
