摘要： A light olefin feed for an olefin conversion process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin prior to the conversion reaction. The water used for the wash is free of boiler feedwater additives, especially basic nitrogenous additives, which adversely affect catalytic function.

摘要： A process for the alkylation of a benzene-containing refinery stream such as reformate with light refinery olefins which is capable of achieving high benzene conversion levels operates in a fixed bed of an MWW zeolite catalyst, preferably MCM-22, in single pass mode in the liquid phase at a relatively low to moderate temperatures with pressure maintained at a value adequate to ensure subcritical operation. High levels of benzene conversion with conversions of at least 90% and higher, e.g. 92% or 95% or even higher are achievable. A high octane product is produced, comprising mono-, di- and tri-alkylbenzenes with lesser levels of the tetra-substituted products. By operating with staged olefin injection, the end point of the alkylation product can be maintained at a low value while, at the same time, achieving high levels of benzene and olefin conversion.

摘要： The present invention provides a process for producing a hydrocarbon fuel composition that includes introducing an olefin feed composition including light olefins to an oligomerization catalyst to yield an intermediate composition including olefins having at least four carbon atoms, introducing the intermediate composition and a second feed of aromatic compounds (e.g., a feed including from 2 to 99.9% benzene or other alkylatable aromatics) to an aromatic alkylation catalyst to yield a fractionation feed to provide a composition which can be further refined to provide one or more hydrocarbon fuel compositions.

摘要： A light olefin feed for an olefin utilization process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin by coalescence separation at a low temperature, typically below 40° C. The coalescence separation technique is effective for separating the olefins from the water with its dissolved contaminants. If desired, a supplemental washing may be carried out by adding additional water to the feed/water mix after the initial wash step but before the coalescer in order to remove provide additional contaminant removal.
