Propane dehydrogenation alternaria alternata propylene by-huahana hydrogen kinoea, ina i ka ma-huahana hydrogen me ke kuai alahele, hiki wale ke puhi e like me ka wahie kinoea, e pili pono i ka waiwai o ka propane dehydrogenation, ke hoohalikeia me ka malamalama hydrocarbon māwae, propane dehydrogenation (hydrogen kuni) ka ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka olefin ma mua o ka propane dehydrogenation kaʻina, nā huahana nui o ka māmā hydrocarbon māwae no ka ethylene propylene, ma ka huahana hydrogen wahie kinoea hui pū ʻia o kalapona ʻehā Hui ʻia kalapona ʻelima, hiki ke hoʻonā i ka propane dehydrogenation iā ia iho me ka ethylene a me ka butene mihi, pyrolysis o hiki i nā huahana ke hoʻomaopopo hou i ko lākou waiwai ponoʻī, i ka manawa like ka maikaʻi o ke kumukūʻai haʻahaʻa, hiki i ka mākeke o ka copolymerization unregulated a me ka copolymerization hopena, ʻoi aku ka waiwai i nā makahiki i hala. .I ka manawa like, me ka hoʻonui ʻana o ka nui o nā hiʻohiʻona noi terminal, ua hoʻonui ʻia ka ʻaoʻao koi o ka mākeke i ka ʻenehana ikehu hydrogen i kekahi ʻano, a ua hoʻomaka ka hapa nui o nā ʻoihana dehydrogenation propane home e hoʻolohe a i ʻole ka hoʻolālā. ʻO kā lākou mau ala kūʻai ponoʻī a me nā hoʻolālā hoʻohana no ka hydrogen ma ka huahana I kēia hihia, ʻo ka propane dehydrogenation, inā i kūʻai ʻia ma ke ʻano he hydrogen industrial a i ʻole ke kumu kūʻai nui o ka hydrogen cell a i ʻole ka hydrogen maʻemaʻe kiʻekiʻe, e hāʻawi i ka hoʻihoʻi waiwai a no laila e hoʻonui ai i ka waiwai o nā hui dehydrogenation propane. .Ma ka hoʻohālikelike, ʻo ka ʻenehana propane dehydrogenation he kaʻina pōkole a me ka hoʻohana haʻahaʻa.Inā hiki ke hui pū ʻia me nā mea hoʻomaʻemaʻe a puni e hāʻawi i ka hydrogen no ka hoʻomaʻemaʻe ʻana a me ka hoʻonui ʻana i nā pōmaikaʻi ma o ka hoʻolako ʻana i nā mea maka, ʻo ka pōmaikaʻi o ka māmā hydrocarbon pohā aia i ka nui o ka hoʻopukapuka kālā, nā ʻano huahana a me ka ikaika ikaika e pale aku i nā pilikia mākeke.ʻO ka hoʻokele waiwai o nā mea ʻelua e hilinaʻi nui ana i ka ethylene a me ke kumukūʻai propylene: ʻoi aku ka maikaʻi o ke alahele dehydrogenation propane i ka wā e kokoke mai ana nā kumukūʻai ethylene a me propylene, a ʻoi aku ka maikaʻi o ke ala ʻoi aku ka maikaʻi o ke ala o ka ethylene ma mua o ka propylene.

ʻO ka propane dehydrogenation maka mea hoʻokahi, me ka hoʻohana wale ʻana i ka propane ma ke ʻano he mea maka, ka propylene wale nō ka huahana a me ka hydrogen huahana, ʻaʻole wale ka pale kalapona kalapona ʻaʻole wale, hiki ke hōʻemi i nā pilikia o nā kumu ʻē aʻe, ʻo ia ka mea hou i kēia manawa i ka koho ʻenehana nui o ka ʻoihana. ʻO ka hapa nui o ka hana ʻana o Kina i ka mea PDH e pili ana i ka ʻaoʻao o lalo, ʻike maopopo ʻia ka hoʻohui ʻana o ka ʻoihana, akā i ka wā lōʻihi, he haiki ke kahua hoʻomohala kaulahao o lalo, ʻoi aku ka nui o ka mākeke, ma ka home polypropylene production hiki pālua ʻia i ka hoʻokūkū mākeke ikaika. Pono e loiloi hou ʻia ka hoʻokūkū o ka ethylene propane dehydrogenation.

Hoʻohālikelike ʻia me ka propane dehydrogenation, ʻoi aku ka nui o ke kaʻina hana hoʻoheheʻe hydrocarbon māmā i nā hopena huahana like ʻole a ʻoi aku ka ikaika o ka mākeke.Ma ka hoʻohālikelike ʻana, ʻo ka hoʻokele waiwai o ke kaʻina dehydrogenation propane e hilinaʻi nui i ka ʻokoʻa kumu kūʻai ma waena o propylene a me propane.Ke loli a emi ke kumu kūʻai o ka propylene, e hoʻemi nui ʻia ka hoʻokele waiwai o ke kaʻina dehydrogenation propane.

No ka ʻoihana polypropylene, ʻoi aku ka liʻiliʻi o ke kumu propane, ʻoiai ua hoʻonui ʻia mai 7% i 2015 a i 15% i 2022, ʻaʻole naʻe ia e noho i ka mainstream ma ka mākeke a he kuleana nāwaliwali ke kumu kūʻai i nā huahana polypropylene.Eia nō naʻe, me ka hoʻomau mau ʻana o ka ikehu māmā a me nā mea kemika ma Kina, ke huli nei ke ʻano o nā kumu aila maʻemaʻe o luna o ka polypropylene, a me ka hiki ʻana mai o ke au "propane", ʻaʻole e mamao loa ma mua o ka naphtha, propane a me ka lanahu. e māhele ʻia i ʻekolu ʻāpana o ka honua.
