    摘要： A method of modifying the activity of a solid acid catalyst by contact with a carboxylic acid is presented. The modified catalyst is exposed to a feed mixture including olefins in a reaction zone, and an effluent including an isomerized olefin product is withdrawn from the reaction zone. The isomerized olefin product includes a more random distribution of internal olefins than the olefins of the feed mixture. The feed mixture and the isomerized olefin product include linear olefins. The isomerization results in no more than about 10 weight percent additional branched, compared to the olefins of the feed mixture, among the olefins of the isomerized olefin product. The isomerized olefin product includes no more than about 20 weight percent dimer. The olefin monomers of the feed mixture and the isomerized olefin product include from about 4 to about 30 carbon atoms. The effluent includes no more than about 20 weight percent ester. The solid acid catalyst may be an acidic ion exchange resin. The feed mixture may include olefins, esters, and carboxylic acid.

    摘要： Processes and systems for the production for pressure management of a polymerization product flowing from a loop polymerization reactor to a separation vessel in a slurry polymerization system are disclosed herein. For example, a process comprises withdrawing the polymerization product from a loop polymerization reactor, and conveying the withdrawn polymerization product to a separation vessel via a first pressure differential and a second pressure differential. The withdrawn polymerization product may flow through the first pressure differential before flowing through the second pressure differential, and the first pressure differential may be less than the second pressure differential.

    摘要： Methods for recycling ethylene from a reaction zone effluent stream from an oligomerization reaction zone, in which the reaction zone effluent stream contains an oligomer product effluent having at least 20 mass % octene(s), include a step of separating the reaction zone effluent stream into a first stream containing ethylene and less than 5 mass % C4+ olefins, a second stream containing butene(s) and less than 10 mass % C6+ olefins, a third stream containing at least 96 mass % hexene(s), and a fourth stream containing at least 96 mass % octene(s). The ethylene-rich first stream is recycled into the oligomerization reaction zone, while the recycle of 1-butene and other butenes is reduced significantly.

    摘要： Processes and systems for the production for pressure management of a polymerization product flowing from a loop polymerization reactor to a separation vessel in a slurry polymerization system are disclosed herein. For example, a process comprises withdrawing a polymerization product slurry from a loop polymerization reactor, conveying the polymerization product slurry through a first line comprising a continuous take-off valve to yield a mixture comprising a vapor phase, wherein the mixture exits the continuous take-off valve, and conveying the mixture through a second line comprising a flashline heater so that the mixture has a Froude number in a range from about 5 to about 100.
