Abstract: A staged complementary pressure swing adsorption system and method for low energy fractionation of a mixed fluid. Two beds in a four-column PSA system are selective for component A, and another two columns are selective for component B. The cycle creates an intermittent A and B product, using the purge effluent from the complementary product fed at an intermediate pressure. This intermittent product is used as purge gas for low-pressure purged elsewhere in the cycle using appropriate storage tanks. The use of an intermediate pressure in this cycle enables continuous production of purified component A and B without the use of compressors. Columns may also be configured to enable pressure to equalize between complementary columns.

Abstract: Active catalysts for the treatment of a low temperature exhaust gas stream are provided containing potassium (K) dispersed on a spinel oxide for the direct, lean removal of nitrogen oxides from the exhaust gas stream. The low temperature (from about 400° C. to about 650° C.), direct decomposition is accomplished without the need of a reductant molecule. In one example, K may be dispersed on a surface of a metal oxide support, such as NiFe2O4 spinel oxide, synthesized using wet impregnation techniques. The K/NiFe2O4 catalyst system converts nitric oxide to nitrogen gas with high product specificity, up to 100%, avoiding the production of a significant concentration of the undesirable N2O product.

Abstract: A vehicular lighting system includes low beam headlamps, high beam headlamps and a control unit configured so that during operation of the lighting system, the control unit determines the operational status of the high beam headlamp and selectively adjusts the illuminating intensity of the low beam headlamp. In particular, the brightness of the low beam headlamp can be increased during periods where the high beam is not being, thereby allowing the low beam to more closely approximate the brightness of the high beam, but without the glare associated with conventional high beam patterns. In this way, artificially low illuminating intensity limitations placed on the low beam headlamps can be overcome during periods where the lighting system is operating but the high beams are not in use.
