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

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.

Provided is a process for oligomerizing n-olefins. The process has the step of reacting (oligomerizing) an amount of one or more n-olefins in the presence of a catalytically effective amount of a two or more metal oxides at a temperature effective to effect oligomerization. The two or more metal oxides are represented by the formula MO/M'O. M and M&#x2032;, are, independently, selected from the group consisting of Al, Ce, Fe, P, W, Zr, and combinations thereof. M and M&#x2032; are different metals or combinations of metals. 'n' and 'n&#x2032;' are positive numbers and vary stoichiometrically depending on the valency of M and M&#x2032;, respectively. Provided is also a process for alkylation of an alkylatable aromatic compound. The process has the step of contacting an amount of one or more n-olefins with an amount of aromatic compound in the presence of a catalytically effective amount of the two or more metal oxides at a temperature effective to effect alkylation of the aromatic compound.

Catalysts for experimentation are produced having a controlled matrix pore structure. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50&#xb0; C. to 200&#xb0; C. for a period of time of about 0.1 to 1.0 hour. The dried catalyst particles can be removed from the substrate by several techniques, including scraping, burning, and deforming the substrate material. The resulting catalytic particles can be produced in an amount of about ca. 3 g to 300 g from slurries with volumes between 5 cc to 500 cc, which are suitable for small scale FCC reactors and for high throughput experimentation.

A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a Calkylating agent under alkylation conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an alkylation effluent comprising secbutylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4 alkylating agent secbutylbenzene fraction is recovered from the alkylation effluent and comprises at least 95 wt % sec-butylbenzene, less than 100 wt ppm of C+ olefins, and less than 0.5 wt % of isobutylbenzene and tert-butylbenzene. The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketene.

A process for increasing the hydrogenation activity, particularly the carbon monoxide hydrogenation activity, of a catalyst or catalyst precursor comprised of a particulate solids support component and a catalytic metal, or metals component, preferably cobalt; cobalt alone or cobalt and an additional metal, or metals added to promote or modify the reaction produced by the cobalt. Treatment of the catalyst, or catalyst precursor is conducted at low temperature ranging from ambient to about 275&deg; C. sufficient to form on the surface of a catalyst precursor, e.g., a cobalt catalyst precursor, a cobalt metal hydroxide, low valence cobalt metal oxide, or mixture of cobalt metal hydroxide and low valence cobalt metal oxide. Sometimes also metallic metal, e.g., cobalt, is also formed, and dispersed on the surface of the support. On reduction, as may be produced by contact and treatment of the catalyst or catalyst precursor with hydrogen, the oxidized metal, or metals component of the catalyst or catalyst precursor is reduced to elemental or metallic metal, and the activity of the catalyst thereby increased. A catalyst, activated or produced in this manner, is a useful composition of matter, the catalyst being particularly useful for efficiently conducting carbon monoxide hydrogenation reactions, especially F-T synthesis reactions, to provide a variety of useful products.
