Catalyst composition which comprises a first zeolite having a BEA* framework type and a second zeolite having a MOR framework type and a mesopore surface area of greater than 30 m/g is disclosed. These catalyst compositions are used to remove catalyst poisons from untreated feed streams having one or more impurities which cause deactivation of the downstream catalysts employed in hydrocarbon conversion processes, such as those that produce mono-alkylated aromatic compounds.

Catalyst compositions and their use in aromatic alkylation processes

A process for producing an alkylaromatic compound comprises providing a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkylating agent, wherein at least the first feed contains an impurity compound comprising at least one of nitrogen, halogens, oxygen, sulfur, arsenic, selenium, tellurium, phosphorus, and Group 1 through Group 12 metals The first feed is passed through an adsorbent comprising a metal-organic framework material under conditions effective to reduce the amount of impurity compound in the first feed and produce a purified first feed. The purified first feed and at least part of the second feed are then contacted with an alkylation catalyst composition under alkylation conditions effective to convert at least part of the alkylatable aromatic compound in the purified first feed to the desired alkylaromatic compound and produce an alkylation effluent.

Production of alkylaromatic compounds

A process for producing a monoalkylated benzene comprises contacting benzene with a mixture comprising dialkylated and trialkylated benzenes in the presence of a transalkylation catalyst composition under transalkylation conditions effective to convert at least part of the dialkylated and trialkylated benzene to monoalkylated benzene, wherein the catalyst composition comprises a metallosilicate zeolite comprising openings defined by 14-membered rings of tetrahedrally coordinated atoms and the transalkylation conditions include a temperature in the range of 160&#xb0; C. to 220&#xb0; C.

A process for producing a monoalkylated benzene comprises the step of contacting benzene with a mixture comprising dialkylated and trialkylated benzenes in the presence of a transalkylation catalyst composition under transalkylation conditions effective to convert at least part of the dialkylated and trialkylated benzene to monoalkylated benzene, wherein the transalkylation catalyst, composition comprises zeolite beta having an external surface in excess of 350 m2/g as determined by the t-plot method for nitrogen physisorption.

In a process for improving the cold flow properties of a hydrocarbon feedstock, the feedstock is contacted with a catalyst composition comprising an EMM-17 molecular sieve and a hydrogenation component under dewaxing conditions effective to produce a dewaxed product having a cloud point and/or pour point that is reduced relative to the cloud point and/or pour point of the feedstock by at least 5&#xb0; C.

Catalytic dewaxing of hydrocarbon feedstocks

The present invention provides an improved method for making molecular sieves having MWW framework structure using precipitated aluminosilicates (PAS), and the use of molecular sieves so made in processes for catalytic conversion of hydrocarbon compounds.

Synthesis of molecular sieves having MWW framework structure

A molecular sieve material, EMM-17, has in its as-calcined form, a total surface area of greater than 550 m/g and/or an external surface area of greater than about 100 m/g as measured by the BET Method, and a specific X-ray diffraction pattern.

Small crystal EMM-17, its method of making and use

Hydrogenation catalysts for aromatic hydrogenation including an organosilica material support, which is a polymer comprising independent units of a monomer of Formula [ZOZOSiCH](I), wherein each Zand Zindependently represent a hydrogen atom, a C-Calkyl group or a bond to a silicon atom of another monomer; and at least one catalyst metal are provided herein. Methods of making the hydrogenation catalysts and processes of using, e.g., aromatic hydrogenation, the hydrogenation catalyst are also provided herein.

Aromatic hydrogenation catalysts and uses thereof

Organosilica materials made from monomers including at least a source of silica that is reactive to polymerize, optionally in combination with at least one additional cyclic monomer. Methods for making such organosilica materials are also described herein.

Organosilica materials, methods of making, and uses thereof

Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

Adsorbent materials and methods of use

A composition is described comprising a molecular sieve having pores defined by channels formed by one or more 8-membered rings of tetrahedrally coordinated atoms, such as a DDR-type molecular sieve, and an amorphous deposit of a boron compound on the molecular sieve.

Boron selectivated molecular sieves and their use in sorptive separations

Methods are provided for synthesizing ZSM-58 crystals with an improved morphology and/or an improved size distribution. By controlling the conditions during synthesis of the ZSM-58 crystals, crystals of a useful size with a narrow size distribution can be generated. Steaming the H-form DDR framework type crystals at a temperature from 426&#xb1;&#xb0; C. to 1100&#xb1;&#xb0; C. for a time period from about 30 minutes to about 48 hours can attain one or more of the following properties: a CH4 diffusivity of no more than 95% of the CH4 diffusivity of the unsteamed H-form DDR framework type crystals; an N2 BET surface area from 85% to 110% of the surface area of unsteamed H-form DDR framework type crystals; and an equilibrium CO2 sorption capacity from 80% to 105% of the equilibrium CO2 sorption capacity of unsteamed H-form DDR framework type crystals.
