Abstract: This invention is a process for converting lower alkanes into their corresponding esters and optionally into various intermediates (such as alcohols) and other liquid hydrocarbons. The alkanes are oxidatively converted to oxy-esters at high selectivity and conversion and at practical reaction rates using at least catalytic amounts of certain class "B" metals and/or metal ions defined by the Pearson definition as "soft" or "borderline". Desirable catalysts comprise such metals as Pd, Tl, Pt, Hg, and Au. If so desired, the alkyl oxy-esters may be converted to alcohols or other intermediates such as alkyl halides. The oxy-esters, alcohols, and other intermediates may optionally be converted to liquid hydrocarbons such as gasoline.

Abstract: A support structure (53) for securing a catalyst structure (52) comprising a multiplicity of longitudinally disposed channels for passage of a flowing gas mixture within a reactor, said support structure being comprised of a monolithic open celled or honeycomb-like structure formed by thin strips or ribs of high temperature resistant metal or ceramic which abuts against one end of the catalyst structure, and extends in a direction perpendicular to the longitudinal axis of the catalyst structure to essentially cover an end face (at either the inlet end or outlet end or both) of the catalyst structure with the support structure being secured (54) on its periphery to the reactor wall. The strips or ribs making up the support structure are bounded together to form a unitary structure having cellular openings at least as large as the catalyst structure channel openings. The cellular openings in the support structure are also positioned to be in fluid communication with the channels of the catalyst structure thus affording essentially unaltered gas flow (50) from the catalyst structure through the support structure.

Abstract: This invention is a catalyst structure having integral heat exchange surfaces and a method for using the structure in highly exothermic processes, such as a combustion process, while maintaining the catalyst and the structure wall at a temperature below the adiabatic combustion temperature.

Abstract: This invention is a HfO2-containing catalyst support material for use in high temperature catalytic processes, such as catalytic combustion, wherein the HfO2 is present in a sufficient amount to impart thermal stability on the catalyst support at temperatures in excess of 1,000 ~C, as well as, heterogeneous, supported-platinum group metal catalyst employing the HfO2containing support material and monolithic catalyst structures in which the HfO2-containing support material is used as a substrate washcoat for the active catalyst material. Also described are high temperature catalytic processes, such as catalytic combustion, employing catalysts and catalyst structures which utilize the HfO2-containing support material.

Abstract: This invention is an improved catalyst structure and its use in highly exothermic processes like catalyst combustion. This improved catalyst structure employs integral heat exchange in an array of longitudinally disposed, adjacent reaction passageways or channels, which are either catalyst-coated (14) or catalyst-free (16), wherein the configuration of the catalyst-coated channels (14) differ from the non-catalyst channels (16) such that, when applied in exothermic reaction processes, such as catalyst combustion, the desired reaction is promoted in the catalytic channels (14) and substantially limited in the non-catalytic channels (16).

Abstract: The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6-diisopropylnaphthalene isomer is obtained in the presence of an acidic crystalline molecular sieve catalyst having twelve membered oxygen rings. The catalyst pore aperture dimension ranges from 5.5 ANGSTROM to 7.0 ANGSTROM . The use of these shape selective catalysts results in a diisopropylnaphthalene stream which is enhanced in beta isomers and enhanced in the desired 2,6-diisopropylnaphthalene isomer. A particularly preferred catalyst is synthetic Mordenite. Specific catalyst modifications are also described to improve selectivity to the desired 2,6-diisopropylnaphthalene isomer.

Abstract: A process for the selective manufacture of 2,6-diisopropylnaphthalene from naphthalene advantageously combines an equilibration reactor to enhance the amount of monoisopropylnaphthalene fed to the alkylation reactor, and the use of a shape selective catalyst in the alkylation reactor, to obtain an alkylation reaction product in which the 2,6-diisopropylnaphthalene isomer comprises greater than 39 mole percent of the total diisopropylnaphthalene obtained. Further, this combination of reaction steps and conditions produces a reaction product in which the ratio of 2,6-diisopropylnaphthalene to 2,7-diisopropylnaphthalene is greater than 1.0, preferably greater than 1.2. Recycled process components are fed to the equilibration reactor where they are combined with fresh naphthalene feed to provide a monoisopropylnaphthalene enriched feed to the alkylation reactor.
