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 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.

摘要： A flow scheme is presented for the production of high purity D-allose from D-glucose. The key reaction is epimerization of D-glucose at C-3 to afford D-allose in per pass yields of at least 7%. The epimerization reaction product is then subjected to concentration, decolorization, and deionization before entering a separation zone, preferably a sorptive separation zone, from which an extract stream enriched in D-allose is obtained.

摘要： A process is disclosed for hydrotreating olefin-containing hydrocarbon streams for the purpose of producing very low olefin concentrations without the use of high pressure hydrotreating. The process is useful in preparing feeds to adsorptive separation zones. In the process the effluent of a hydrotreating reaction zone is passed into a stripping column. Preferably, substantially all liquid flowing downward through the lower section of the column is withdrawn and then passed through a hydrogenation reactor. The hydrogenation reactor effluent is passed into the bottom of the column to allow removal of dissolved hydrogen.
