Kev tsim cov styrene koom nrog lub dehydrogenation ntawm ethylbenzene nyob rau hauv qhov kub thiab txias, qis-siab gas-phase adiabatic reactorCov tshuaj tiv thaiv yog thim rov qab thiab endothermic. Muaj ob peb lwm qhov kev tshwm sim uas tau muab los ntawm Vasudevan li al. 2 uas haus ethylbenzene thiab tsim cov khoom tsis zoo.
Koj ua li cas hloov ethylbenzene rau styrene?
Direct dehydrogenation ntawm ethylbenzene rau styrene account rau 85% ntawm kev lag luam ntau lawm. Qhov kev rov ua dua yog ua nyob rau hauv lub vapor theem nrog lub zog tshaj lub catalyst uas feem ntau ntawm cov hlau oxide. Cov tshuaj tiv thaiv yog endothermic, thiab tuaj yeem ua tiav los yog adiabatically los yog isothermally
YPuas yog ethylbenzene ib styrene?
Feem ntau ntawm styrene yog tsim los ntawm ethylbenzene, thiab yuav luag tag nrho cov ethylbenzene tsim thoob ntiaj teb yog npaj rau styrene ntau lawm.
Koj ua li cas styrene?
Cov qauv kev tsim cov styrene suav nrog cov alkylation ntawm benzene nrog ethylene los tsim ethylbenzene, ua raws li dehydrogenation ntawm ethylbenzene rau styrene Styrene undergoes polymerization los ntawm txhua txoj kev siv hauv plastics technology los tsim ntau yam polymers thiab copolymer.
Koj ua li cas ethylbenzene?
Ethylbenzene yog tsim los ntawm cov catalytic alkylation ntawm benzene nrog ethylene, los yog los ntawm cov xylenes sib xyaw los ntawm isomer sib cais thiab catalytic isomerisation, los yog los ntawm 1, 3-butadiene hauv ob-kauj ruam txheej txheem qhov twg butadiene hloov mus rau vinylcyclohexane uas yog tom qab ntawd dehydrogenated.
