    摘要： A nonwoven composite has a first surface, a second surface, and a thickness extending between the first and second surfaces. The nonwoven composite comprises a plurality of natural fibers, a plurality of binder fibers, and a VOC-absorbing material. The binder fibers are bonded to or interlocked with the natural fibers. The VOC-absorbing material is dispersed within the nonwoven composite in such a manner that the density of the VOC-absorbing material in the nonwoven composite is greatest adjacent to the second surface of the nonwoven composite. A method for producing a nonwoven composite is also described.

    摘要： An alkylation-transalkylation process for the production of a monoalkylated aromatic compound is disclosed which maximizes the production of desirable monoalkylaromatic compounds, while limiting transalkylation catalyst deactivation. The process entails the combination of an alkylation reaction zone, a first seperation zone, a second separation zone, and a transalkylation reaction zone wherein the alkylation catalyst and transalkylation catalyst are dissimilar and where the alkylation catalyst is comprised of phosphoric acid material and the transalkylation catalyst is comprised of a crystalline aluminosilicate material. The transalkylation catalyst deactivation is reduced by transalkylating only dialkylated aromatic compounds. Additionally, the transalkylation catalyst is regenerable utilizing a hot liquid hydrocarbon wash.

    摘要： A catalyst regeneration apparatus for the oxidation of coke from a spent catalyst, said coke being converted to CO, and for the conversion of the CO to CO.sub.2. Hot regenerated catalyst is recycled from a dense bed in the regeneration zone to mix with incoming spent catalyst in a mixer zone. The mixer zone operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, preferably air. After the mixing of spent and fresh catalyst is substantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design. There is a transfer section connecting the mixer zone to the regeneration zone through when the relatively large amount of the regenerating gas is admitted. The transfer section is preferably a substantially horizontal surface having an outside perimeter intermediate the outside perimeters of the regeneration and mixer zones. Regeneration gas addition is made through multiple perforations in the transfer section.

    摘要： A process for the catalytic dehydrogenation of a dehydrogenatable C.sub.2 -plus feed hydrocarbon which comprises the steps of: (a) passing a feed stream comprising the C.sub.2 -plus feed hydrocarbon into an isothermal dehydrogenation zone and through at least one bed of dehydrogenation catalyst maintained at isothermal dehydrogenation conditions selected to convert at least about 50 weight percent of the dehydrogenatable C.sub.2 -plus feed hydrocarbon and producing an isothermal dehydrogenation zone effluent stream comprising hydrogen, unconverted C.sub.2 -plus feed hydrocarbon and C.sub.2 -plus product hydrocarbon; (b) forming an oxidation catalyst bed feed stream by admixing an oxygen-containing stream with the isothermal dehydrogenation zone effluent stream; (c) passing the oxidation catalyst bed feed stream through a bed of hydrogen selective oxidation catalyst maintained at selective oxidation conditions and producing an oxidation zone effluent stream having a reduced concentration of hydrogen and an increased temperature; (d) passing the oxidation zone effluent stream into an adiabatic dehydrogenation zone and through at least one bed of dehydrogenation catalyst maintained at dehydrogenation conditions selected to convert additional unconverted C.sub.2 -plus feed hydrocarbon and producing an adiabatic dehydrogenation zone effluent stream comprising hydrogen, unconverted C.sub.2 -plus feed hydrocarbon and C.sub.2 -plus product hydrocarbon; and (e) recovering the C.sub.2 -plus product hydrocarbon.
