âC5/C9 Hydrogenated Petroleum Resin Mea Hana Hoʻomākaukau

2022-10-26

Ethylene māwae C5 hakina lewa kaomi rectification intercepts 45-75â isoprene enriched mea like maka A; ethylene māwae C5 hakina lewa kaomi rectification intercepts 25-45â isoprene i hoʻonaʻauao ʻia e like me ka mea maka B; Hoʻoponopono ʻia ka ʻāpana Ethylene cracking C9 ma lalo o 0.08ï½0.095MPa, Petroleum Resin a me ka hakina me kahi paila o 140ï½180â lawe ʻia e like me ka mea maka C. ka lakio nui o 1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization maka mea D;

Ma hope o ka hoʻoheheʻe ʻia ʻana o ka polymerization maka D ma o ka hale kiaʻi sieve molecular sieve 4A, hoʻokō ʻia ka hydrogenation koho koho Petroleum Resin me kahi catalyst Pd/Al2O3 e wehe i ka alkyne, Petroleum Resin a laila 0.05 a 0.5 wt% o FriedelCrafts catalyst e hoʻohui ʻia, a laila. prepolymerized i ka lumi wela no 0.5 a 1.5 hola, Petroleum Resin a laila calcium hydroxide Ua wehe ʻia ka catalyst mai ka hui ʻana me ka methanol, a ma hope o ka distillation, ʻo Petroleum Resin ka hapa o ka polymer raw material E loaʻa kahi paila o 25 a 180 ° C. ;Petroleum Resin ka polymerized maka mua E ua prepolymerized i loko o ke kiʻekiʻe-press reaction kettle me ka hoʻouluulu ma kahi mahana o 180°C a 230°C no 3 a 5 hola. E kiʻi i ka hua dimerization F o Centaolefin a me Styrene a i ʻole Methyl Styrene;

Ke hoʻohana nei i ka huahana dimerization F i ʻōlelo ʻia ma luna nei ma ke ʻano he mea maka, hui pū ʻia ka Petroleum Resin me kahi mea hoʻoheheʻe diluting ma kahi lakio nui o 1: 0.1 a 1.0, Petroleum Resin a hoʻohui i ka boron trifluoride catalyst e helu ana no 0.1 a 0.5% o ka huina nui. o ka mea e hoʻopololei ai i ka polymerization ma 30 a 65°C 2 a Ua loaʻa mai kahi ʻeleʻele melemele a ʻeleʻele polymerization i loko o 5 mau hola. Ua wehe ʻia ka hopena polymerization mai ka catalyst me ka hui ʻana o ka calcium hydroxide a me ka methanol no ka loaʻa ʻana o kahi solution resin melemele melemele; ʻO Petroleum Resin ka hopena resin ma luna nei i hoʻopaʻa ʻia i ka desalination uila a me ka hoʻomaʻemaʻe wai ma 50 a 80 ° C. Pass active Al2O3 solid bed ma â;

Hoʻoheheʻe ʻia ka C5/C9 petroleum resin solution ma hope o ka hoʻomaʻamaʻa mua ʻana i luna i loko o ka dilution solvent ma kahi ratio nui o 1:1 a hiki i 5, a ua hoʻokau ʻia i ka hopena hydrogenation i mua o kahi catalyst Pd i hoʻololi ʻia e loaʻa ai kahi hopena resin diluted hydrogenated. . ï½295â, he 10.0ï½17.0MPa ka ikaika o ka hydrogen reaction, He 0.125ï½0.333h/1 ka wikiwiki o ka pane o ka Petroleum Resin; , C5/C9 hydrogenated petroleum resin.
