    摘要： Paraffin alkylation using solid, particulate catalyst is carried out by preparing an alkane-catalyst mixture in a wash zone, passing the alkane-catalyst mixture to a plug flow reactor where a minor amount of olefin is introduced to contact the alkane-catalyst mixture and react to form alkylate and the alkane-catalyst-alkylate mixture is passed through the reactor with a minimum of back mixing to restrict the reaction of alkylate with olefin, thus substantially preventing polymerization. The alkane-catalyst-alkylate mixture, substantially free of olefin is passed to a disengaging zone where the liquid is removed and the solid particulate catalyst is recovered and returned to the wash zone for recycle. The alkane is present in the reactor in sufficient molar excess to react substantially all of the olefin. Any unreacted isoalkane is recycled to the reactor with make-up isoalkane added to maintain the molar excess. The preferred catalyst is an acid washed silica treated with antimony pentafluoride and more preferably treated with alkane at low temperature, e.g. -30.degree. to -160.degree. C.

    摘要： In an alkylation process wherein the amount of hydrogen fluoride (HF) acid catalyst required to maintain a desired HF acid/hydrocarbon ratio in a plurality of alkylation reactors is contained in the lower portion of a common settler vessel, the improvement comprises: dividing the lower portion of the common settler vessel into a plurality of chambers for containing the desired amount of HF acid catalyst, such that a leak affecting the catalyst handling system for one of the plurality of reactors would only spill the amount of liquid HF acid contained in one of the chambers, and would not affect the liquid HF acid level in a non-leaking chamber.

    摘要： A novel family of crystalline, microporous gallophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures from gallophosphate gels containing a molecular structure-forming template. The family comprises distinct species, each with a unique crystal structure. Calcination removed volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst based in chemical reactions such as hydrocarbon conversion.

    摘要： A continuous catalytic process for oligomerizing lower olefins to heavier hydrocarbons wherein a continuous liquid olefinic feedstream is diluted with a liquid alkane stream, is improved by a technique which comprises cooling catalytically converted effluent, fractionating the effluent to obtain a condensed lower aliphatic recycle stream, a liquid C.sub.3 -C.sub.4 product stream, a liquid product stream consisting essentially of C.sub.5.sup.+ hydrocarbons and a gaseous C.sub.2.sup.- gaseous stream by the sequential fractionation steps of: debutanizing the cooled effluent to obtain the liquid C.sub.5.sup.+ hydrocarbon stream and a condensed lower aliphatic stream; de-ethanizing a portion of the lower aliphatic stream to recover gaseous offgas stream and a C.sub.3 -C.sub.4 alkane product stream; and optionally recycling at least a portion of the condensed aliphatic stream from the debutanizing step for dilution of the olefinic feedstream.
