    摘要: A simulated moving bed adsorptive separation process for preparing the separate feed streams charged to naphtha reforming unit and a steam cracking unit has been developed. The feed stream to the overall unit is passed into the adsorptive separation unit. The desorbent in the adsorptive separation is C12 hydrocarbons. The simulated moving bed adsorptive separation separates the components of the feed stream into a normal paraffin stream, which is charged to the steam cracking process, and non-normal hydrocarbons which are passed into a reforming zone. The desorbent is readily separated from the normal paraffin stream and from the non-normal paraffin stream and the simulated moving bed adsorption zone is operated at an A/Fn ratio of from about 0.90 to about 0.92.

    摘要: The present invention comprises a process for removal of oxygenates from a paraffin-rich or olefin-rich paraffin stream which comprises passing a feed stream, comprising one or more C10 to C15 feed paraffins or C10 to C15 olefin-rich paraffin stream and one or more oxygenates through an adsorbent bed comprising one or more adsorbents selected from silica gel, activated alumina and sodium x zeolites to remove essentially all of said oxygenates; and recovering said paraffins. A second adsorbent bed may be employed to more thoroughly remove these oxygenates.

    摘要: The present invention is a process for producing phenyl-alkanes by paraffin adsorptive separation followed by paraffin dehydrogenation and then by alkylation of a phenyl compound by a lightly branched olefin. The adsorptive separation step employs a silicalite adsorbent and, as the desorbent, a C5-C8 linear paraffin, a C5-C8 cycloparaffin, a branched paraffin such as isooctane, or mixtures thereof. The effluent of the alkylation zone comprises paraffins that are recycled to the adsorptive separation step or to the dehydrogenation step. This invention is also a process that that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups that to produce modified alkylbenzene sulfonates. In addition, this invention is the compositions produced by these processes, which can be used as detergents having improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates, as lubricants, and as lubricant additives. This invention is moreover the use of compositions produced by these processes as lubricants and lubricant additives.
