    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 catalyst comprising palladium on a support (102) and a partial combustion process in which the fuel is partially combusted using that catalyst. The palladium catalyst (106) may also comprise palladium mixed with metals selected from Group VIII or IB, may be graded (Fig. 1b) such as to have higher activity in the forward edge (112) of the catalyst, or may be placed on a support comprising zirconia. The choice of catalysts (106) and supports (102, 110) specified each solves a variety of problems dealing with the long term stability of the palladium as a partial combustion catalyst. The catalyst structure is stable in operation, has a comparatively low operating temperature, has a low temperature at which oxidation begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is at a temperature below the autocombustive temperature and may be used at that temperature or it may be fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.

    Abstract: This invention is a combination process for producing elemental bromine using a seawater feed. The process involves a series of steps in which seawater is acidified, chlorinated, and air stripped to remove the bromine. The stripping effluent is reacted with an SO2 stream to convert the bromine to hydrogen bromine and H2SO4 in the air stream. The process continues by absorbing hydrogen bromide and H2SO4 from the resulting acidic fog to produce an aqueous H2SO4 stream containing HBr. The HBr is stripped from the liquid stream and passed to an oxidation reactor where it is catalytically oxidized with an oxygen-containing gas to produce a stream of Br2 and H2O. The hot reactor effluent is quenched and the product Br2 is separated from the H2O and inert gases such as air. In the figure 2 seawater enters pipeline (202) and is mixed with an H2SO4 stream (200). The resulting stream (214) is sent to a stripping column (218) where air stream (216) strips the bromine from the liquid. The vapor B22 stream (222) is mixed with SO2 (224) which is contacted with a water stream. The resulting aqueous H2SO4/HBr stream (236) is heated and mixed with a chlorine stream (240). A portion of the chlorine is introduced through line (241) to the bottom of stripping column (242) and separates with stream (244) into stream (246) containing H2O4 and HCl separates with stream (244) into stream (246) containing H2SO4 and HCl and stream (248) containing Br2. The Br2 product (260) is discharged from decanter (254) into the purification unit (255).

    Abstract: This invention is a process for converting hydrocarbonaceous feeds, particularly lower alkanes, into their corresponding esters and optionally into various intermediates (such as alcohols) and optionally into liquid hydrocarbons. The hydrocarbonaceous feeds 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. Mercury is most desired. If so desired, the oxy-esters may be converted to alcohols or other intermediates such as halides. The oxy-esters, alcohols, and other intermediates may optionally be converted to liquid hydrocarbons such as gasoline.
