Processes and apparatuses for benzene and/or toluene methylation under conditions of low temperatures in one of a vapor phase, a liquid phase or a mixed vapor-liquid phase, in an aromatics complex for producing para-xylene are described. More specifically, a process for producing a xylene isomer comprising reacting oxygenates with an aromatic feedstock comprising toluene and/or benzene in a methylation zone operating under alkylation conditions including one of a vapor, a liquid phase or a mixed vapor-liquid phase in the presence of a catalyst to provide a product stream comprising the xylene isomer is described.

Processes and apparatuses for methylation of aromatics in an aromatics complex

This present disclosure relates to processes and apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to a process for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex.

This present disclosure relates to processes for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to a process for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex using mild reaction conditions, namely a combination of low temperatures and elevated pressures using a zeolite with lower number of external acid sites.

A catalyst and a process for using the catalyst are presented. The catalyst is a heterogeneous catalyst and includes active metal halides bonded to functional groups. The functional groups are bonded to a polymeric backbone to form the structure supporting the catalyst. The catalyst is useful for the dimerization of acetylene to convert the acetylene to a larger hydrocarbon, and in particular to dimerize acetylene to vinylacetylene.

The present invention relates to minimizing benzene, toluene, and an A9/A10 recycle loop in a zero benzene aromatics complex. More specifically, the present invention relates to a minimizing benzene, toluene, and an A9/A10 recycle loop in a zero benzene aromatics complex wherein the aromatic feed has a low methyl to phenyl ratio, and where the aromatic feed has a high methyl to phenyl ratio.

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.

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 catalyst is present for use in an olefin cracking process. The catalyst is a zeolite that has been loaded with an alkaline earth metal. The alkaline earth metal loaded catalyst has an increased steaming tolerance and increases the useful life of the catalyst during the cracking process and the regeneration cycle.

OCP catalyst with improved steam tolerance

The invention provides a method to avoid catalyst damage and achieve longer catalyst life by selecting appropriate materials for reactor spacers, liners, catalyst binders, and supports, in particular, by not using crystalline silica-containing and high phosphorus-containing materials, if the presence of even small amount of steam is anticipated. In addition, alkali metals and alkaline earth metals are avoided due to potential damage to the catalyst.
