This disclosure relates to a catalyst composition comprising (a) MCM-22 family material; and (b) a binder comprising at least 1 wt. % of a titanium compound based on the weight of said catalyst composition, wherein said titanium compound was anatase and rutile phases.

Catalyst composition and its use thereof in aromatics alkylation

A process for producing a monoalkylated aromatic compound in an alkylation reaction zone, said process comprising the steps of:

Monoalkylated aromatic compound production

This disclosure relates to a process for alkylating an aromatic hydrocarbon with an alkylating agent to produce an alkylated aromatic product, said process comprising contacting said aromatic hydrocarbon and said alkylating agent with a catalyst composition under alkylation conditions effective to alkylate said aromatic hydrocarbon with said alkylating agent to form an effluent comprising said alkylated aromatic product, wherein said catalyst composition comprising (a) MCM-family material; and (b) a binder comprising at least 1 wt. % of a titanium compound based on the weight of said catalyst composition, wherein said titanium compound was anatase and rutile phases.

A process for producing a monoalkylated aromatic compound in an alkylation reaction zone, comprising providing upstream of said alkylation reaction zone a reactive guard bed having a catalyst of *BEA, MWW, or FAU framework structure and an alkylation feed wherein at least a portion of any reactive impurities are removed from the alkylation feed to form an effluent; and providing the effluent and a first catalytic particulate material which comprises MCM-56 and an alumina binder sized 50-60 mesh and having a ratio of surface area over volume ratio in the range of 241 to 2867 cm-1 and optionally additional alkylating agent to said alkylation reaction zone; and contacting said alkylatable aromatic compound and said alkylating agent with said catalytic particulate material in said alkylation reaction zone maintained under alkylation conditions, to form a product comprised of said monoalkylated aromatic compound.

The present invention provides an improved process for conversion of feedstock comprising an alkylatable aromatic compound and an alkylating agent to desired alkylaromatic conversion product under at least partial liquid phase conversion conditions in the presence of specific catalyst comprising a porous crystalline material, e.g., a crystalline aluminosilicate, and binder in the ratio of crystal/binder of from about 20/80 to about 60/40. The porous crystalline material of the catalyst may comprise a crystalline molecular sieve having the structure of Beta, an MCM-22 family material, e.g., MCM-49, or a mixture thereof.

Liquid phase alkylation process

A process for removing polar components from a process stream in a refinery process without cooling the process stream. The process stream is fed to a first adsorber unit to remove contaminants containing sulfur at substantially the same elevated temperature by exposing the process stream to a metal oxide and/or a mixed metal oxide to remove the sulfur containing contaminants and produce a metal sulfide and a desulfurized process stream. The metal sulfide may be regenerated by exposing it to a stream of oxygen and the desulfurized process stream exposed to the regenerated metal/mixed metal oxide to remove moisture from the stream. The stream is then processed within a second adsorber unit to remove nitrogen containing contaminants at substantially the same elevated temperature by exposing the stream to a molecular sieve and/or zeolite.

Process for removing polar components from a process stream to prevent heat loss

The present disclosure provides a process for selectively producing a desired monoalkylated aromatic compound comprising the step of contacting in a reaction zone an alkylatable aromatic compound with an alkylating agent in the presence of catalyst comprising a porous crystalline material under at least partial liquid phase conditions, said catalyst manufactured from extrudate to comprise catalytic particulate material of from about 125 microns to about 790 microns in size, having an Effectiveness Factor increased from about 25% to about 750% from that of the original extrudate, and having an external surface area to volume ratio of greater than about 79 cm.

Alkylaromatic production process

A catalyst composition comprises (a) a MCM-22 family molecular sieve; and (b) a binder, wherein the MCM-22 family molecular sieve is characterized by an average crystal agglomerate size of less than or equal to 16 microns. The catalyst composition may further have a second molecular sieve having a Constraint Index of less than 12, e.g., less than 2. Examples of molecular sieve useful for this disclosure are a MCM-22 family molecular sieve, zeolite Y, and zeolite Beta. The catalyst composition may be used for the process of alkylation or transalkylation of an alkylatable aromatic compound with an alkylating agent.

Catalyst composition, the method of manufacturing, and the process of using thereof in hydrocarbon conversions

The invention relates to a process for converting hydrocarbons with a catalyst comprising a crystalline molecular sieve composition which is obtainable by crystallizing a pre-formed extrudate mixture in a reactor and, during crystallization, removing excess alkali metal hydroxide from the pre-formed extrudate. The pre-formed extrudate mixture comprises at least one source of ions of tetravalent element Y, at least one source of alkali metal hydroxide, water, optionally at least one seed crystal, and optionally at least one source of ions of trivalent element X. The reaction mixture has the following mole composition: Y:X=10 to infinity; OH:Y=0.001 to 2; and M:Y=0.001 to 2; wherein M is an alkali metal. The amount of water in the mixture is at least sufficient to permit extrusion of said reaction mixture.

Molecular sieve composition

The present invention provides an improved process for conversion of feedstock comprising an alkylatable aromatic compound and an alkylating agent to desired alkylaromatic conversion product under at least partial liquid phase conversion conditions in the presence of specific catalyst comprising a porous crystalline material, e.g. a crystalline aluminosilicate, and binder in the ratio of crystal/binder of from about 20/80 to about 60/40. The porous crystalline material of the catalyst may comprise a crystalline molecular sieve having the structure of Beta, an MCM-22 family material, e.g. MCM-49, or a mixture thereof.
