Ethylbenzene-raws li thev naus laus zis yog siv nyob ib ncig ntawm 90% ntawm cov khoom tsim styrene.Lub catalytic alkylation ntawm EB siv txhuas chloride los yog lwm yam catalysts yog thawj kauj ruam nyob rau hauv cov txheej txheem ntau lawm (ie zeolite catalysts).Siv ntau lub txaj adiabatic lossis tubular isothermal reactors, EB yog tom qab dehydrogenated rau styrene nyob rau hauv lub xub ntiag ntawm chav kub kub tshaj hlau-chromium oxides los yog zinc oxide catalysts.Qhov kev thov rau styrene hauv cov kua dej yog kwv yees ntau dua 15 lab metric tons, thiab nws feem ntau txiav txim siab los ntawm qhov kev thov rau nws cov ntawv thov ntau yam.Western thiab Eastern Europe, nrog rau North America, muaj peev xwm tshaj plaws txhua xyoo rau kev tsim khoom styrene.
