An improved continuous process for converting lower olefinic hydrocarbon feedstock to C.sub.5.sup.+ liquid hydrocarbons by contacting vapor phase olefinic feedstream with acid zeolite catalyst in the presence of recycled diluent stream rich in C.sub.3 -C.sub.4 hydrocarbons in an enclosed reactor at elevated temperature and pressure. The improved technique comprises a system for cooling reactor effluent to recover a heavier hydrocarbon stream containing a mixture of C.sub.3 -C.sub.4 hydrocarbons ...

In recirculatively precollatively copying a set of plural simplex original documents onto both sides of copy sheets to produce a desired plural number precollated duplex copy sheet sets, by normally copying the documents only once in each copying circulation of the document set, and by forming a buffer set of copies of alternate document pages being duplexed which buffer set copies are printed on only one side, and temporarily stored in a duplex store and by copying alternate documents onto the ...

There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is a CuZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable copper salt such as copper nitrate.

There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is a GaZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable gallium salt such as gallium nitrate.

There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is an NiZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable nickel salt such as nickel nitrate.

There is provided a process for the direct partial oxidation of methane with oxygen, whereby hydrocarbons having at least two carbon atoms are produced. The catalyst used in this reaction is a cadmium-manganese oxide catalyst.

A tetrafluoroethylene/hexafluoropropylene copolymer with high drawability is provided. Also provided is a process employing the polymer and an article coated with the polymer.

A integratable transmitter/receiver configuration for higher frequencies includes a reception path mixer multiplying a reception signal and a carrier frequency signal with one another. A controlled first intermediate frequency oscillator can be turned off by a switch control signal and has a frequency range being reversible by a first range control signal. A demodulator is connected downstream of the reception path mixer and receives the output signal of the first intermediate frequency oscillat...

Higher alkyl diaryl sulfonium salts, e.g., octadecyldiphenylsulfonium tetrafluoroborate, are useful as anti-obesity agents.

An aromatic hydrocarbon is alkylated with an alpha olefin containing three to 10 carbon atoms, or more, by intimately contacting the alpha olefin and the aromatic hydrocarbon with a catalyst produced by contacting (a) a refractory metal oxide/silica support such as alumina/silica wherein the silica content of the support is from two to 95 weight percent and the metal oxide content of the support is from five to 98 percent with (b) a tris(cyclopentadienyl)trinickel dicarbonyl. This process result...
