There is described a process and a catalyst for the hydroalkylation of an aromatic hydrocarbon, particularly benzene, wherein the catalyst comprises a first metal having hydrogenation activity and a crystalline inorganic oxide material having a X-ray diffraction pattern including the following d-spacing maxima 12.4&plusmn;0.25, 6.9&plusmn;0.15, 3.57&plusmn;0.07 and 3.42&plusmn;0.07.

Hydroalkylation of aromatic hydrocarbons

A zeolite catalyst suitable for use in shape-selective hydrocarbon conversion processes. The catalyst is modified by incorporation therein of a hydrogenation-dehydrogenation functional metal, followed by gradient selectivation with an organosilicon compound under conversion conditions, wherein the gradient selectivation conditions are characterized by a progressive temperature gradient. The use of a progressive temperature gradient during the in situ selectivation procedure unexpectedly yields a catalyst in which the hydrogenation-dehydrogenation function is stabilized, thereby enabling long duration hydrocarbon conversion processes with low by-product make.

Zeolite catalysts having stabilized hydrogenation-dehydrogenation function

The invention discloses a method for converting alkane to oxygenate which comprises the following steps: (i) contacting an alkane-containing gas with non-metal, regenerable, electrophile ions in a concentrated sulfuric acid medium under conditions sufficient to provide electrophilicly activated alkane and reduced electrophile ions; (ii) contacting said electrophilicly activated alkane with sulfate to form a sulfate ester; (iii) exposing the sulfate ester to hydrolyzing conditions sufficient to convert it to oxygenate; and (iv) collecting the oxygenate.

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of a zeolite catalyst which contains alkali metal, alkaline earth metal, or a combination thereof present in excess of a stoichiometric amount.

Process for co-production of dialkyl carbonate and alkanediol

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of an amorphous aluminosilicate catalyst containing alkali metal, alkaline earth metal, or a combination thereof.

A process for producing nitrous oxide comprises reacting ammonia with nitric oxide and/or oxygen in the presence of a catalyst comprising a Group VIB metal oxide, to produce a reaction mixture comprising nitrous oxide, and optionally recovering the nitrous oxide from the effluent mixture.

A process for the synthesis of alkylene carbonates, such as ethylene carbonate, by reacting alkylene oxides with carbon dioxide in the presence of a porous solid support catalyst containing an alkali or alkaline earth metal component.

Process for producing alkylene carbonates

A process for hydrocracking heavy, high aromatic content feeds, such as cycle oil, using a catalyst composition containing a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal.

Process for hydrocracking cycle oil

A process for hydrocracking heavy hydrocarbon feeds using a catalyst composition containing a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. The hydrocracking product has high isoparaffin to normal paraffin ratios and with minimal ethane and methane byproducts at high conversions. The hydrocracking step is useful in processes for producing high quality lubricating oil basestocks, along with naphtha and distillate products.

Process for selective wax hydrocracking

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of a Group 5 or Group 6 metal oxide catalyst.

A novel synthesis composition of a solid acid containing zirconium, in addition to a rare earth element, such as cerium, has the potential for catalytic conversions of hydrocarbons, especially for isomerization of paraffins, ring opening of cyclics, hydrocracking, alkylation, hydrogenation of polynuclear aromatics, selective catalytic reduction of nitrogen oxides, and oligomerization of light olefins.

Acid catalyst composition

A method is provided for co-producing dialkyl carbonate and alkanediol by reacting alkylene carbonate with alkanol in the presence of a complex salt catalyst having a formula A.sub.x (M.sub.y O.sub.z), wherein A is an alkali metal or alkaline earth metal, M is a Group 5 or Group 6 transition metal, O is oxygen, x is 1 or 2, y is 1 or 2, and z is an integer from 3 to 6.

There is provided a method for preparing an acidic solid oxide having a reduced particle density, where the acidic solid oxide comprises a Group IVB metal oxide modified with an anion or oxyanion of a Group VIB metal. An example of this acidic solid oxide is zirconia modified with tungstate. The acidic solid oxide having a reduced particle density is prepared by coprecipitating the Group IVB metal oxide along with the anion or oxyanion of the Group VIB metal in the presence of a salt. This acidic solid oxide is particularly effective as a paraffin isomerization catalyst.
