Abstract: This invention is a self-contained NOx sensor assembly. It may be used to detect NOx levels in a flowing gas stream such as might be found in an exhaust gas from a combustion process and to produce a measurable electrical output related to the content of NOx measured. The NOx sensor assembly is of a configuration that may be detached from a mounting and replaced. The sensor assembly comprises two sensor elements one of which is made up of a catalyst on a temperature measuring device. The other is a gas stream ambient temperature measuring device. The catalyst is selected and configured so that it selectively reduces NOx and the resulting heat of the reaction raises the temperature of the allied temperature measuring device. The sensor assembly also contains a NOx reductant source. The sensor assembly may be placed in a moving vehicle for measuring NOx levels in its exhaust gas.

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: This invention is a process for the regeneration of solid acidic hydrocarbon conversion catalysts, but particularly certain transition aluminas and zeolites promoted with Lewis acids (preferably BF3) which have been used in the alkylation of isoparaffins with olefins. The process involves the removal of some portion of the reaction product residue adhering to the solid catalyst by contact with a solvent to partially recover the catalyst's initial activity.

Abstract: This is a catalyst and a process for partially hydrogenating polycyclic and monocyclic aromatic hydrocarbons such as benzene, naphthalenes, biphenyls, and alkylbenzenes to produce the corresponding cycloolefins. The catalyst is a hydrogenation catalyst comprising ruthenium and a promoter metal, such as cobalt, on a composite support. It is a process in which the product cycloolefin is produced in high yield and with high selectivity.

Abstract: This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromine. The inventive catalyst composition comprises cerium bromide on certain zirconia containing supports. The zirconia support, preferably largely in the baddeleyite phase, stabilizes the cerium bromide catalyst against cerium oxide formation at operating temperatures and gives the catalyst excellent activity at lower temperatures.
